glass cleaner on lcd screen brands

We updated this article in January 2023 to add more frequently asked questions about screen cleaners based on extensive testing done by the Good Housekeeping Institute. Our original top-rated picks, selected by the GH Cleaning Lab remain the same.

In recent years, we’ve all become more acutely aware of just how many germs are out there. And, as a result, we"ve all adopted practices to help keep high-touch surfaces around us clean. And is there anything that gets touched more than the phones, laptops and other gadgets we use to stay connected to the world around us? They are essential lifelines, so it"s no wonder they get assaulted with dust, greasy fingerprints, grime and germs — lots and lots of germs. Regularly cleaning your phone and laptop is important not only to keep your gadgets looking great but for your personal safety and to help your devices work better, too. When the Good Housekeeping Institute Home Care & Cleaning Lab tests screen cleaners, we first evaluate items for safety, ensuring any products we’re considering don’t contain potentially gadget-damaging chemicals like ammonia. Then, we test all screen cleaners on a variety of devices, both large and small, to measure efficacy. Our top picks for screen cleaners include top-performing products from our latest tests and those highly rated in online consumer reviews.

Below our picks, you can read more about how we evaluate screen cleaners in our Lab — plus learn all about how to shop for screen cleaners and find out whether or not it’s safe to use disinfecting wipes on phones. Check out our guides to cleaning your laptop the right way and the best way to clean a TV screen.

All of us have a tendency to treat the driver"s seat as our personal throne. That"s where we"re in our element, so we get comfortable—and complacent. Whether our fingers were last tapping on our phone screen, grasping the handle of a wrench, or carefully unwrapping a half-melted Hershey bar, we all tend to jump in, tune the radio, adjust the AC, and set a destination on the nav screen—all without first washing our hands.

And if you have a family? Other drivers use the car and its touchscreen, too. Of course, kids can"t resist touching any kind of screen, ever, and who knows where those tiny fingers have been? All parents have swiped their car"s touchscreen and felt... mystery muck. Yuck.

Touchscreens are likely one of the dirtiest, most germ-covered surfaces of any automobile. Sure, your dash gets dusty and your floorboard accumulates (a disturbing amount of) trash. However, it"s that dash-mounted screen that gets the most fingers, and therefore germs, on it.

Not necessarily. Many typical household glass cleaners contain either ammonia or alcohol. Most manufacturers recommend avoiding harsh chemicals on touchscreens, as they can affect functionality and perhaps damage the surrounding dashboard.

Sure, it"s cheaper and easier to use plain ol" Windex or Glass Plus, mainly because you"ve probably already got that stuff. Despite the temptation, though, you should avoid using household glass cleaner on your car"s touchscreen unless you"re positive the one you"re using contains neither ammonia nor alcohol. Besides, you may already own a great screen cleaner and not realize it.

Many modern automotive detailing products, including Chemical Guys Interior Cleaner and Meguiar"s Total Interior Detailer, are safe and effective to use on your car"s touchscreen. Read the label to be sure.

The fact is, there"s an even less expensive method to clean your car"s touchscreen, no products required—except a microfiber towel. (Again, you want to avoid scraping dust particles across the surface of your touchscreen to prevent scratches, so always use a clean microfiber towel.)

Many of the experts and gearheads in our Hearst Autos test garage told us they rarely use any kind of cleaner on their personal touchscreens. Up and down the line, those who saw us testing and photographing screen cleaners—we"re talking about people whose opinions we trust and whose bylines our readers know and respect—told us that whenever they get behind the wheel, they just drip a bit of water onto a clean microfiber towel, and wipe. Done.

As a parent, however, I"m left asking the question: Will a simple water wipe eliminate germs in the family SUV? Yeah, no. Sorry, but knowing my children, and the impressive but disgusting level of filth they can achieve, I"m going to use a cleaning agent on my car"s touchscreen.

To get to the bottom of whether car screen cleaners were truly necessary, we used a very scientific methodology. That is, we got our fingers and hands dirty, and touched the heck out of a screen in a test vehicle in the Hearst Autos stable. We let it dry for a while, and then cleaned it according to the product"s instructions. We did that five times.

We first made sure all the products did the job they claimed to do—and they all did. The wipes left droplets on the screen, which required a second wipe with a microfiber. But they all cleaned the chocolate and grease off the screen, leaving it clean and clear.

While using, we looked for any greasy film or residue left behind. We also considered any particularly strong odors, and took note of cleaners that left residual streaks. Most did, but all came away clean with a soft buff—that is to say, a few more gentle wipes with the microfiber towel.

Word to the wise: Don"t discount a screen cleaner because it leaves streaks on your screen. Take your time and do it right. We noticed far too many people online complaining that the product they used wasn"t some sort of magical solution that cleaned perfectly with just one wipe. All screen cleaners—all glass cleaners, really—will streak unless you take the time and care to give the surface a soft buff at the end of the process.

The more you use an electronic device, the dirtier it"ll get over time. Given that smartphones, laptops, tablets, and TVs are a major part of our lives, you"re probably curious about how to clean their screens. When it comes time to give your device a good wipe-down, you may be confused about where to start, especially given the sensitive nature of this cleaning task. Even though most smartphones are waterproof, you definitely shouldn"t scrub one like you would a dirty dish in the sink.

Below, you"ll find our favorite screen cleaners, as well as some tips on how to clean your smartphone. And hopefully, we will also help ease your concerns about catching or spreading COVID-19 via your smartphone.

Apple says you should use a soft, slightly damp, lint-free cloth to clean your iPhone. On the other hand, Google says you can use ordinary household soap on a damp cloth to remove stains. Both agree that cleaning wipes — those that have 70% isopropyl alcohol — are fine, too. That is, just as long as you don"t get moisture into any of your smartphone"s openings. Apple also says 75% ethyl alcohol wipes and Clorox Disinfecting Wipes are safe to use: Just make sure you don"t use products containing bleach or hydrogen peroxide!

It"s also important to turn off your device before you clean its screen, and you should never apply the cleaner directly to the screen, either. Spray the cleaner on a lint-free cloth instead, and avoid using rougher materials like paper towels. Consider keeping your smartphone in a sealed case, too, so it"s easier and safer to wipe down with disinfectant wipes.

The CDC recommends cleaning high-touch surfaces regularly — including our phones. Both the Wall Street Journal have reported that there is no need to compulsively clean your phone, but it"s still a good idea to give it a quick wipe down every now and then.

Dr. Donald W. Schaffner, an extension specialist in food science and a distinguished professor at Rutgers University says if you"ve been near anybody who has been coughing or sneezing, you should most definitely clean your phone. However, if you"re diligent about washing your hands, there"s no reason to clean your phone more than once a day ... unless it"s potentially been exposed to the virus.

Unless you"re using a disinfecting wipe to clean your devices, chances are that whichever screen cleaner you buy will not kill the COVID-19 virus. Most screen cleaners aren"t disinfectants. If you"re shopping for a disinfectant, make sure you check to see if it"s an EPA-registered disinfectant that can kill the COVID-19 virus.

Even though most screen cleaners don"t kill viruses, experts say that the chance of catching a virus like COVID-19 from your smartphone is minimal when compared to the risk of being near someone who is infected with the disease.

There are steps you can take to minimize your mobile device"s exposure to germs and viruses, however. The Federal Communications Commission recommends the following:Keep your phone in your pocket, purse, or car when you leave the house

Now that you know how to clean your devices, find the best screen cleaner for your needs among these thoroughly evaluated picks. We"ve recommended cleaners that come in large-sized bottles that"ll last for months at home, some smaller travel-friendly cleaners for keeping your screens looking flawless on the go, and even some hypoallergenic screen cleaners for folks who are sensitive to chemicals. Trust us, whether you"re sick of the smudges or just want to keep germs and bacteria at bay, you"ll find the best screen cleaners for every kind of device below.

Screens can scratch easily, and even paper towels and tissues contain fibers that can do damage. “Your best bet is to use a soft, anti-static microfiber cloth—the kind used to clean eyeglasses and camera lenses—and wipe in a circular motion,” says John Walsh, who cleans more than 250 TVs a year in his role as a CR photographer. (Some TV manufacturers will include a cloth for this purpose.) “Gently wipe the screen with a dry cloth to remove dust and other debris, but don’t press too hard,” he says.

You may also want to wipe down the TV’s cabinet, and make sure dust isn’t clogging the vents that help dissipate heat. If the TV is on a stand and not tethered to the wall, Walsh suggests cleaning with one hand while supporting the TV with the other to prevent the set from tipping over. However, CR strongly recommends anchoring all stand-mounted TVs using anti-tipping straps designed for this purpose.

If there are hard-to-remove stains, you can dampen the cloth slightly with distilled water and gently clean the screen. Don’t spray water directly onto the screen; that could cause a shock or component failure if water seeps into the inner workings of the set.

For the most stubborn stains, you can try using a solution of very mild dish soap highly diluted with water, once again applied to the cloth and not to the TV itself. (As a guideline, Panasonic used to recommend a 100:1 ratio of water to soap.) LCD screens, in particular, are very sensitive to pressure and can scratch easily, so don’t press hard.

From the television to the computer to the tablets, screens and monitors are all around your house. As more and more devices move into the touch-screen mode, you may very well find you’re frequently cleaning TV screens and computer monitors. While you may be quick to grab some paper towels, glass cleaner and start wiping away, stop and ask yourself this: is this the best way to clean this screen? There are many different considerations for cleaning the screens and monitors in your house. Here’s a closer look at what you need to know.

Most of the TVs found in homes today have flat screen monitors and are quite different compared to screens on older models. Cathode Ray Tube (CRT) TVs of the past (like the big 1980s-style sets you may recall) had a thick glass screen that was relatively safe to wipe clean with paper towels and window cleaner. Not so with today’s flat screen models. Much of what’s on the market today has a liquid crystal display, or LCD, monitor that produces images. LCD televisions are also thinner and lighter than CRTs.

The make-up of an LCD monitor or screen, however, features a special type of material that is sensitive to chemicals, such as a glass cleaner. Likewise, a plasma display panel (PDP) is made with small cells that contain electrically charged ionized gases—the plasmas.

One of the most important steps to remember is to turn the device off before you begin cleaning. When the screen is dark it will be easier to see the dirty areas. Keep in mind that using harsh chemicals on these screens could ultimately damage or even ruin the television or computer. And it’s not just the cleaners you need to be aware of; kitchen towels or paper towels could also cause scratches and leave the screens covered in lint.

Knowing and understanding how to clean your screens and monitors can help ensure you’re able to use and enjoy your devices for years to come. Here are a few suggestions for properly cleaning these specialty screens.

Probably one of the most important considerations is to never spray any type of cleaning fluid or even water directly onto the screen. While the old CRT screens were pretty much water-tight, the same can’t be said for today’s modern screens. Screens today are made of layers upon layers of glass, plastics, various display elements, and other materials. When liquid comes in contact with the screen’s edge it can be pulled in, like a capillary, to the layers. Once this happens, you will likely notice something that looks like a blob on your screen, and the liquid will most likely never evaporate without leaving some remaining damage.

You may think that grabbing the bottle of glass cleaner you already have on hand is fine for cleaning screens and monitors. But think again. Using many of these common cleaning products can end up causing serious damage. Ammonia-based cleaners (such as traditional window cleaning spray), for example, could cause a chemical reaction with the coating on the screen or cause clouding. Some electronics stores sell specialty cleaners for use on screens, but you can also make cleaning solutions at home. One option is to combine equal parts of water and vinegar for a homemade cleaning product. But don’t spray anything directly onto the screen. Instead, spray the solution onto a lint-free cloth and gently wipe the surface.

When was the last time you cleaned your TV? As one of the most prominent pieces of equipment in your home, your TV is probably exposed to more than you think. And we’re talking dust, cobwebs, pet hair and dirt, not to mention germs and bacteria in the air. Think of how often you’re touching your TV and the remote too. If your TV is near the kitchen, lingering odors and oils in the air could also be hitting your screen’s surface.

Figuring out what to use to clean your TV isn’t that complicated, but there are definitely one or two things you should avoid. Do turn your TV off before you get started. Don’t reach for the typical glass cleaner. Here are some other specifics.

Cloth: A soft microfiber cloth or flannel is the best material to use when cleaning a delicate flat screen. Paper towels or rags are a little rougher and could cause scratches you’d rather avoid. Plus, they’re generally thin and cheaper, leading to bits of paper breaking off and getting stuck on your screen.

Cleaning Solution: Moistening your cloth with a bit of water is generally more than enough to clean off everyday dust and debris. But if it’s not, you can always use a special screen cleaning solution, which is designed to get out gunk while being gentle on your TV surface. Harsh cleaning solutions like glass cleaner or other cleaners you would use for the rest of your house could react badly with the screen and cause permanent discoloration.

Specialty Products: There are also specially formulated products like wipes or cleaning sprays that are designed to be used on TV and computer screens without causing damage to the surface or the color. Sprays often come with a microfiber cloth included, and all of these products are made with mild, non-toxic ingredients.

Simple microfiber cloths like these Amazon-branded ones are perfect for cleaning off delicate screens either dry or moistened slightly with a cleaning solution. The cloths are gentle on surfaces and can be tossed in the washing machine and re-used.

It’s hard to beat wipes when it comes to ease of use. We like these Windex wipes because they come in large quantities from a trusted brand, made with gentle ingredients that are safe to use on all screens, from your TV to your laptop.

This spray comes with a plush microfiber cloth included, which is helpful, and makes screens look shiny and new in a matter of seconds. And according to the product notes, each use keeps your screen cleaner for longer, requiring less product each time.

We always like to include an environmentally conscious option, like this EcoMoist screen cleaner, which is non-toxic, alcohol free, and hypoallergenic according to the manufacturer notes. It also comes with a microfiber cloth included.

As the weather warms, it"s time for everyone"s "favorite" pastime: spring cleaning. While you"re dusting off the shelves and shoveling out a winter"s worth of detritus, spare a moment to check your TV. Dust and grime can accumulate there, and over time it can become more and more noticeable. And if you have children, there may be an array of fingerprints and other smears on the screen.

The short version? Don"t use liquids, don"t press too hard, don"t use any traditional cleaners. Microfiber cloths are good, but be gentle. Modern TVs are predominantly plastic and therefore far easier to scratch than windows or your phone.

Want the longer version? Here"s what the top TV manufacturers say about cleaning their screens:Cleaning your 4K, OLED, or LED TV screen with a soft, dry cloth is recommended. The goal here is to avoid scratching the screen. Gentle, circular motions tend to give better results, since the circular motion hits each area from several angles in a single swipe.

Caution: Don"t spray water or other liquids directly on the TV, as electric shock could occur.Turn the TV off and let it cool down for a few minutes before unplugging it.

To clean the frame and screen, gently wipe it with a microfiber cleaning cloth. Make sure to wipe the TV frame and screen as gently as possible. TV screens are fragile and can be damaged when pressed too hard.

Important: Never use any type of window cleaner, soap, scouring powder, wax, or any cleanser with solvents such as alcohol, benzene, ammonia, or acetone. Never use abrasive pads or paper towels. If you do, you can scratch the screen or strip the anti-glare coating off the screen and cause permanent damage. Never spray water directly onto the TV. Make sure to wipe the TV as gently as possible. TV screens are fragile and can be damaged when pressed too hard.Gently wipe the screen or the exterior with a dry, soft cloth, such as an eyeglass cleaner.

For inks from oil markers on the screen, soak a cloth in a non-soap synthetic cleanser diluted (by less than 1% ) with water. Squeeze the cloth tightly to eliminate excess liquid, then wipe gently to remove the ink. Use non-soap cleansers cautiously because it may cause environmental problems when disposed improperly.

So why not Windex? Regular Windex is formulated for glass windows, plus a few other surfaces. It contains ammonia and alcohol, not the friendliest of chemicals. S. C. Johnson doesn"t explicitly say not to use Windex on TVs, but it offers Windex Electronics wipes and cleaners, so infer what you will. The better screen cleaners will clearly state that they do not contain alcohol or ammonia.

At last count, I found a billion companies making TV screen cleaners. Almost all of these are something like 99 percent water, 1 percent other stuff. Years ago I tested a handful and found them, on average, to work well enough. If you don"t have luck with a simple cloth and possibly distilled water, a screen cleaner is worth a try, and as a bonus you can also use it for your laptop, tablet and cell phone screens. Plus, they come with a microfiber cloth. If they don"t clearly state they don"t contain alcohol and ammonia, however, I would skip them.

So yeah, cleaning your TV is a good idea. But just remember that they"re exceptionally fragile. Why risk marring their surface by using cleaning methods the companies themselves don"t advise? If you damage your screen with cleaners, you won"t be able to fix it.

My advice? Get a nice microfiber cloth (if your TV didn"t come with one), and use that. If that doesn"t fix your smudges, try a cloth moist with water. Don"t press too hard. There"s less than a millimeter between your finger and a broken TV.

Screen cleaning kits are fine, though most people won"t need them. Remember, like all TV accessories, the store is selling them because they probably make more profit on that $20 kit than on a $500 TV.

This is the ultimate guide to properly cleaning your flat-screen television without scratching it or causing any potential damage. Included in this guide will be the best cleaning techniques, as well as the ideal products to accomplish a brand-new appearance on your TV. This guide is full of must-have knowledge for absolutely anyone who wants their television to remain in pristine condition. As a bonus, this guide will also provide you with a detailed explanation and instructions on how to clean your TV remote control.

Nowadays, most televisions are manufactured with a soft plastic screen. As a result of this, TV screens are delicate and can be easilydamagedif cleaned with an improper solution or technique. Accidentally using the incorrect product on your television could result in permanent damage, such as fogging, discoloring, or scratching.

When cleaning a television screen, two different techniques work extremely well. The first technique focuses on spraying down a microfiber cloth and wiping the Televisions screen. Alternatively, you may spray a minimal amount of non-ammonia based cleaner onto the TVs screen and gently wipe it away. These two techniques are proven safe and will not result in any permanent damage to your TV’s screen, as long as you follow the necessary detailed instructions when performing the cleaning.

Certain products and items you never want to use on the screen of your TV since they will cause permanent damage. When gearing up to perform a television cleaning, you will want to avoid using regular tap water, wood-based wipes, isopropyl alcohol solution containing more than 50% alcohol, regular Windex, or any cleaners that are ammonia-based.

Many products that are not made specifically for cleaning electronics will harm your television. If regular tap water is used on the television screen, a visible residue will appear after the water has dried. Instead of utilizing tap water, you may choose to use distilled water combined with a microfiber cloth. The combination of distilled water with the microfiber cloth will cause any dust on the screen’s surface to cling to the damp cloth. Distilled water will also ensure that the anti-reflective coating on your TV’s screen does not become worn-out.

Though Windex is a common go-to product for cleaning many devices and appliances, using it on a television screen can cause permanent damage. The reason behind this is because Windex is an ammonia-based cleaner. Ammonia-based cleaners may cause a chemical reaction between the ammonia-based cleaner and the coating on the Televisions screen or cause clouding.

It is essential to avoid the use of any wood-based cleaning wipes on a TV screen. Wood-based cleaning wipes include paper towels, Kleenex tissues, along with any similar products. If wood-based wipes are used on the TV’s screen, there is a strong possibility that you would be left with a multitude of visible, permanent scratches on the screen. The reason why the scratching often occurs is how rough the fibers of these products are combined with how soft the screen on the TV is.

You have a few technique options to choose from when preparing to clean a TV screen. A 50% isopropyl alcohol-based spray, also known as a lens cleaner, is a simple option that many lean towards. When using an isopropyl alcohol spray, you will want to pay close attention to the level of alcohol in the spray and be sure to avoid any alcohol-based sprays that contain more than 50% alcohol, as this will over-dry the television screen.

When choosing to utilize the lens cleaner technique, you will also want to use a clean, soft microfiber cloth that does not shed any fibers. If the microfiber cloth does shed fibers, you will find that sometimes after you’ve already cleaned the TV, you have to clean it again. This is due to the small static electricity charge produced when wiping the TV’s screen, which will attract the fibers of a microfiber cloth.

Optionally, specific products are intended for use on electronics that are extremely gentle as they do not contain ammonia or alcohol. Windex makes a special electronics cleaner that works phenomenally and is highly recommended. Additionally, the product “Screen Mom” is specially formulated for televisions and is also a fantastic product.

If the television is not dirty but has acquired a collection of dust particles on the surface, compressed air may be the best option for this job. Using compressed air will inevitably eliminate the worry of causing potential damage to the screen since there is no possible way to damage the television with air. Compressed air is an easy, inexpensive, and fast way to clear any dust from the television, leaving the TV appearing brand-new.

The first option entails simply spraying the microfiber cloth down with the cleaning solution and using that to wipe the television screen. If this is the method that is chosen, you will want to be cautious of the amount of solution used. Ideally, the cloth should only be slightly damp after you’ve sprayed it down.

Accidentally applying too much solution onto the microfiber cloth and using the excessively wet cloth on the TV screen may result in permanent damage. When too much cleaning solution is applied to the TV screen, the cleaner tends to run down the screen into the bezel and any other nearby electronics.

Alternatively, you may mist the TVs screen directly with a small amount of the cleaning solution that you’ve chosen. Immediately after misting the screen, you will want to gently wipe away the mist with a microfiber cloth. If this is the option that you would like to utilize, be sure to be extremely careful to not spray too much cleaner onto the television – as this may drip onto the bezel along with any other nearby electronics very rapidly, resulting in permanent damage.

IMPORTANT: When wiping a television screen with any wipe, be sure to be gentle, and refrain from applying any excessive pressure. Applying too much pressure on the screen will result in distorted pixels.

Where can you purchase inexpensive microfiber wipes and ammonia-free cleaners? Both microfiber wipes and ammonia-free cleaners are commonly found at your local big-box stores such as Walmart, Home Depot, Lowes, Menards, and the Dollar Tree.

Microfiber cloths are commonly located in the automotive aisle of any big box store, and the lens cleaner can often be found bundled in kits for eyeglasses. Alternatively, Amazon possesses an extensive assortment of microfiber wipes and appropriate cleaning solutions that can be shipped directly to your door.

Recent studies from multiple universities have confirmed that the TV remote is the single dirtiest item in a typical home and is a hotbed for bacteria and viruses.

This is because the TV remote is one of the most overlooked household objects when cleaning a home. TV remotes are commonly touched multiple times a day by nearly every person in a household. However, no one ever thinks to clean it. The rubber buttons trap and preserve all sorts of dirt, skin flakes, and hair.

When performing a deep clean on your TV remote, all you need when performing a deep clean is rubbing alcohol, also known as isopropyl alcohol, which comes in a solution or a spray cleaner. Typically, you’ll find this at your local grocery, pharmacy, or hardware store as a 50% water and 50% isopropyl alcohol mixture. Combine this with a clean toothbrush, q-tips, and a microfiber cloth.

You’re going to begin by taking the batteries out of your remote, so your TV doesn’t blow up while you touch all the buttons. Once your batteries are out, take a clean toothbrush, a motorized toothbrush preferably, and start brushing out the debris from between the buttons on your remote, starting at the top of your remote and making your way to the bottom.

If there are any tighter crevices that the cloth couldn’t get to, use a q-tip sprayed with the isopropyl alcohol-water mixture and deep clean between the buttons. Once finished, put the batteries back inside of the TV remote. You can rest easy knowing that the dirtiest part of your home is now the cleanest.

Regularly cleaning your LCD monitor keeps it free of dust, smudges, and germs. Wiping with a dry microfiber cloth is the safest cleaning option and is surprisingly effective at removing germs. You may need to use a dampened microfiber cloth to get rid of stubborn smudges and stuck-on debris, though. If you"re worried about germs, consider using a vinegar and water solution or a Lysol wipe on the screen. Be sure to check the device’s user manual first to make sure it’s okay to use liquids!

A couple of decades ago, glass cleaner was a relatively safe product to use for many household cleaning chores, including cleaning the family television set -- well, the screen, anyway. The belief that glass cleaner is benign and a great option for getting grease, grime buildup and fingerprints off all the surfaces you might like to see through is probably a holdover from those simpler times. There are a couple of problems with that notion when dealing with modern electronics, like laptop monitors and flat screen TVs. Modern electronics are very different from simple windows. Actually, there are even window styles these days that you shouldn"t treat with conventional glass cleaners.

Although ammonia is often cited as the principal ingredient that makes glass cleaner a bad choice for cleaning electronics, there may be any number of compounds in glass cleaning products that can damage delicate electronic equipment, especially screens and other displays. Even some late model CRT televisions sported glass treated with anti-glare film that was prone to yellowing and cracking from repeated exposure to glass cleaner.

One problem with getting the word out about how harmful glass cleaner can be is that it may take multiple applications for a user to start to see the damage, which presents as a yellowish tint or fogging effect. Screens and monitors may also become brittle and start to crack in places. The damage is cumulative, and over multiple applications, anti-glare and anti-static coatings as well as other synthetic surface materials will begin to break down.

Check the operating instructions for the recommended cleaning methods for all of your electronic devices and particularly those with screens or displays. If the directions say you"re free to use glass cleaner, fine. Chances are they won"t, though.

When operating instructions aren"t available, clean electronics with a slightly damp, soft, lint-free, cotton cloth moistened with distilled water or a 50 percent solution of water and white vinegar. Never use paper products like paper towels. Paper can scratch coated glass and some plastics. It also leaves small particulates behind that can be hard to get off later.

If water on a soft cloth isn"t strong enough to remove smudges and grime, try using a microfiber or optical cloth instead. Microfiber has dense hairs that grab and hold grease and dirt for those occasions when a cotton cloth isn"t getting the job done.

To avoid scratching your laptop, make sure any cloth you use is clean and soft, and always rub gently. If you apply too much pressure to your laptop screen, you may create dead spots, or non-functioning pixels, so take your time and be gentle. Once the screen is clean, avoid touching it with your fingers.

If you"re using a manufacturer"s approved cleaning solution like isopropyl alcohol on your laptop or other electronic device, never pour or spray liquid directly on the case, keyboard or screen. Dab a little on a clean cloth and wipe. The cloth should be moist, not wet.

Some manufacturers advocate cleaning monitors and flat screens from left to right and then from top to bottom in overlapping strokes. However you get the job done, keep moisture away from speakers, vents and keyboards, and wipe everything dry afterward.

Ammonia isn"t the only cleaning solvent ingredient you should avoid when taking care of your electronic devices. Unless your equipment manufacturer indicates otherwise, steer clear of:

As with any electronic item, televisions attract dust and are magnets for smudges and children"s fingerprints. Luckily, learning how to clean a flat-screen TV is fairly straightforward, requiring little time and few materials.

Regardless of whether you have an LCD or a plasma TV, all flat-screen TVs are made out of thin, flexible materials and should be treated very gently. They have extremely sensitive components, and using chemical cleaners may lead to a broken or blank screen (so skip the window cleaning spray!). Even ordinary kitchen towels or paper towels can cause marks and scratches on the screen. Here"s the right way to clean a flat-screen TV and prevent costly damage.

Clean a flat-screen TV once a week to wipe away the inevitable smudge marks, dust, and fingerprints that will accumulate. Giving it a regular wipe down will prevent dirt and oil from building up.

Shutting off your monitor will not only help you see where dirt and dust have collected, but it will also give your screen time to cool down. A warm or hot screen will be harder to clean, increasing the chances that you"ll accidentally damage it if you scrub too forcefully.

If you take a quick survey of the different cleaning recommendations from various flat-screen TV manufacturers, you"ll quickly discover that many of the directions conflict with each other. When in doubt, check your owner"s manual or look online at the manufacturer"s website for instructions on how to clean your flat-screen TV. This cautionary step will prevent you from doing something the manual warns against, thus voiding your warranty.

Gently wiping the screen with a dry, soft cloth may be the only universally agreed-upon method for cleaning a flat-screen TV. While this will likely take care of any surface lint, it may not be enough to remove oil or dirt. Be warned, an attempt to scrub the screen by using any amount of pressure may only cause the liquid crystals inside to misalign or burn out.

Unless your owner"s manual specifically prohibits it, carefully wipe the screen with a damp, lint-free cloth. When using water, be sure to spray it onto the cleaning towel rather than directly onto the screen. This will give you more control over where the water is going and how much is being used. Have a dry towel handy for carefully drying off the screen.

In certain instances, like when your TV gets mixed up in a food fight or when a child with grimy hands insists on touching the screen, you may need to use a little soap to clean the surface.
