If you are determined to give toothpaste a go I would certainly experiment with a disposable piece of plastic and with different toothpastes; certain brands of smoker"s toothpastes for example are very aggressive and have quite large particles in them which could end up doing more harm than good. I would tend to keep clear of Brasso, Dura-Glit, etc, all of which have anti-oxidents in them to remove the tarnish off brass and I reckon could react with plastic (but there again, you could experiment). The abrasive which is considered to be the finest and produces the best polish is something called "Jeweller"s Rouge" which is high quality, 100% pure, very finely ground iron oxide. We used this in the labs as the final polishing agent when preparing opaque mineral specimens for reflected-light microscopy.

Another option (and a darned sight easier!) is to have the LCD cover replaced - I understand from posts on other threads that this costs just a few dollars.

Today, almost every home has a TV or monitor with an LCD screen. The new screen pleases the eye with its purity and radiance, but after a few months of use, there is already a scuff, a layer of dust, and sometimes there are scratches. Scratches are the most common problems that are unavoidable after a long period of use. They cannot be completely removed, but they can be hidden well enough to make them invisible. How to remove scratches from a computer monitor or TV at home?

If the damage to the screen or display is not very deep, then try to correct the situation with Vaseline. You will need water, a clean microfiber cloth, petroleum jelly:

Take the eraser - it should be clean without any dirt, so as not to stain the screen. The eraser is necessary to be surely soft and white, it is better if it is new.

Important! Scratches on your screen appeared from careless handling or due to the fact that you used the wrong means. To continue to prevent this problem, read about how to wipe the PC monitor at home.

Thus, it is necessary to polish the surface of the screen until the scratch becomes subtle or disappears completely. The alcohol solution will dissolve the anti-reflective coating and fill the cavity of the scratched surface.

Apply a little toothpaste to a cotton swab and rub it in a circular motion into the damaged area. You need to polish the surface for several minutes until the scratches become invisible.

Important! Be very careful when using such products. To make sure that the tool does not ruin the screen, test it on a small area in the corner of the screen.

This method is quite dangerous and with careless movements can only increase the number of problems on the screen. Therefore, before using this method of removing scratches, it is recommended to try other methods.

Apply a thin layer of varnish to the paper applied to the scratch so that the varnish is laid down like a stencil. Use a small brush or toothpick to apply. Carefully remove the paper so as not to smudge the varnish.Before turning on the screen, make sure that the varnish is completely dry.

We"ve all had that moment: You"re sitting at your computer or laptop and the light hits your screen in a way to reveal an unsightly accumulation of streaks, fingerprints, and dust.

To help, we round up the most important things to know about cleaning your computer screen, whether it"s a Mac or PC. While it"s a simple process, there are a few important rules to keep in mind to make sure you"re doing it safely.

Computer screens are not all made the same, and thus can"t all be cleaned the same way. You"ll want to be careful no matter your screen type, but it"s helpful to know that displays come in two categories:Glass-coated screens: The screens on newer iMac displays and MacBooks have a glass overlay. Glass displays are a little less delicate than LCD or LED screens, and mild cleaning solutions, like rubbing alcohol, are generally safe to use on them.

LCD or LED screens:Windows computers and most touchscreens and matte displays are typically not coated in glass. Extra care should be taken with these screens so not to damage the pixels that make up the display.

To clean a computer screen, you really just need two things: A microfiber cloth and filtered or distilled water. That"s to say you don"t need a special store-bought cleaning solution.

If you"d like some extra sanitation power, an equal parts mixture of water and vinegar is safe no matter your screen type. If you know that your display is glass-coated, you can also use an equal parts mixture of water and 70% rubbing alcohol.What you needTwo lint-free microfiber cloths

d3sign/Getty ImagesTurn the computer or laptop off.For safety reasons, begin by letting the device cool down completely. Dust, fingerprints, and smudges are also easier to spot on a black screen.

If any marks remain, wipe with a lightly moistened cloth.For glass-coated screens, you can use a mixture of equal parts water and vinegar or rubbing alcohol. For LED or LCD screens, use only water. Spray or lightly dab the solution directly onto the cloth and carefully wipe the screen from left to right.

Buff with a dry cloth and air-dry.If any streaks remain once the screen dries, gently buff them with the dry cloth. Before you turn your computer or laptop back on, allow the screen to dry completely.Note:Apple claims that you can use 70% isopropyl disinfecting wipes to clean any Apple product. Just remember not to get any liquid into the device"s ports or openings — to avoid this, you might want to wring out the wipe to remove any excess liquid before using it.

For the best advice for cleaning your screen, it"s a smart idea to check your owner"s manual, which provides the manufacturer"s specific recommendations. But since screens are especially susceptible to damage, there are a few general guidelines that apply, no matter the type of screen you own.

Turn off your computer before cleaning the screen. This is just safe practice where any amount of liquid is involved, but more specifically, any static on the screen could create a shock and damage the internal components.

Do not use abrasive cleaning solutions. This includes bleach (or any products containing bleach), hydrogen peroxide, or all-purpose spray cleaners. Using an abrasive cleaner can ruin the finish of your screen.

Use filtered or distilled water. Especially in areas with hard water, water containing minerals like calcium and magnesium can damage your screen or leave even more streaks.

Use only soft microfiber cloths.Even a fabric as soft as a cotton shirt has snags and uneven particles that can scratch a computer screen. For this reason, avoid T-shirts, towels, and paper towels. The exception is the Apple Pro Display XDR or iMac, which requires a special polishing cloth.

Never spray cleaning solution directly onto the screen. To avoid any risk of damage from excess moisture, mist the solution directly onto the microfiber cloth instead.

Do not wipe in circles. Wiping in circles can create uneven pressure and ultimately lead to screen damage. It"s also more likely to create streaking. Wipe in tight, Z-shaped motions, or in broad strokes from side to side.

Do not scrub.Apply gentle pressure only. Hard scrubbing can damage the internal components of the screen and could leave scratches or spots of discoloration or dead pixels that won"t go away.Melanie Weir

You"ll find as many methods for cleaning a TV screen as there are people you ask. Then, just to add to the confusion, consult your TV"s owner manual and add another method or two.

TV screens are a magnet for dust. A simple weekly flick-over with a soft duster reduces the frequency you need to actually get stuck in and do a proper clean. That"s a good thing. And when you do need to do some polishing, the duster removes potentially dangerous particles that could be rubbed in and create scratches.

It"s very important that the cloth be washed regularly — something most people probably don"t do. Any trapped grit equals disaster when rubbed across your precious screen, and built-up gunk reduces their effectiveness, so just drop them in the washing machine after each use.

This is optional. If regular dusting does the job, great. But many people swear by these. They act like dust magnets and a gentle sweep over the screen can lift the dust completely. Pledge Grab It dry electrostatic cloths are popular and are available in most supermarkets.

But the fact is you simply cannot get a TV streak-free unless you use a bit of dampness. The odd Catch-22 is that for the first few months of owning a new TV only a light dusting is needed to keep it beautifully streak-free. It"s only after the first mystery household blobs and bits start to appear than the owner takes to their screen with a damp cloth — and that’s when the first streaks appear.

You can buy any of a billion or so HDTV/computer monitor cleaning solutions. If you do make sure there is no alcohol, acetone, acetate or ammonia in the solution. They will strip the screen of its magical chemical coating which helps reduce screen reflection.

Mostly because a dark screen makes it easier to see faint streaks or grime. Also, because it"s the sensible thing to do when introducing even tiny amounts of liquid to an electronic device.

Give it a gentle swish with a duster or a dry electrostatic cloth until all the dust is gone. Even small amounts of dust can act like sandpaper under a cloth, so be thorough. If there are no grubby bits or streaks on the screen after dusting then congratulations — the job is complete!

Apply a small amount of your cleaning solution directly to a micro-fibre cloth (never spray directly on to the screen) and wipe evenly across the screen starting from the top and working down. Catch any drips or streams if they start to flow downwards.

This step is only needed for faint traces of streaks which may remain. Use your second, dry micro-fibre cloth and very gently polish out the streaks. Do not apply any pressure to the screen as you polish. Your TV is comprised of several thin layers and it"s all too easy to permanently damage your set by pressing too hard against these delicate components.

LCDs can get dirty for any number of reasons. Fingerprints and dust are typically the main two contributors. However, as in the case of more recent portables, marks may develop on the screen as well. These marks are a result of the keycaps rubbing up against the LCD surface.

If the keyboard in your PowerBook has been lifted up to install RAM (or for any other reason), you should check to make sure that the keyboard is properly seated. When reinstalling the keyboard make sure all the tabs on the leading edge are fully inserted into their corresponding slots. Also ensure that the heat sink or heat exchanger are installed correctly otherwise the keyboard will sit high thus coming into contact with the LCD surface.

So how do you clean fingerprints, dust or marks from a LCD? Firstly try water on a soft cloth. It is important that you do not use a cloth that may be abrasive. For example cloths made from synthetics may be abrasive. Make sure the cloths you use are wood-pulp and lint-free with extremely low polyester content. Never use paper towels.

It is important to note that the surface of the LCD is coated with an anti-glare coating. This surface also offers scratch resistance to a good degree. This surface is not however scratch proof. Likewise it is important to note that chemical agents can react with this surface as well therefore be very careful when selecting which chemical cleaners you intend to use.

So which chemicals can you use to clean the LCD? Water is naturally the best however there will be times when water will just not do the job. Regrettably water alone is not very good at removing oils and other contaminants left behind on a LCD.

Some people use vinegar with water as an all over plastics cleaner for portables. Vinegar & water is the only "safe" glass cleaner for plastics, but this has no anti-static properties, does not resist finger-printing and cannot prevent scratching or extend the life of your LCD display screen surface.

Be very careful of glass cleaners. LCD display screens are almost universally made of plastic. Plastics and computer manufacturers consistently do not recommend alcohol or ammonia - based cleaners. Repeated applications of alcohol on plastic will turn your screen surface "yellow", make it brittle and cause "stress cracking" (hairline scratches) on your screen surface.

While there are many commercial products available that will work without damaging the plastics, Apple has tested a product called Klear Screen made by Meridrew Enterprises (http://www.klearscreen.com) and found it does not cause any harm to the plastics.

Isopropyl alcohol can be used also to clean LCDs without the worry of damaging the anti-glare coating on a LCD. The only caution though is that you do not use this option regularly. However from time to time you may need to remove that stubborn oily fingerprint or marks that just seem to not want to come of the screen.

The best and easiest way to clean a LCD with isopropyl alcohol is with the use of Isowipes manufactures by Kimberly-Clark (order code: 6835). These wipes comes in a bottle dispenser with 75 wipes. Isowipes are available through most chemists.

Whenever cleaning an LCD it is always best to use water unless of course you need to remove stubborn dirt thus simply cannot be removed by water alone.

Preventative maintenance is always good as well. Let"s take screen marks as an example on the PowerBook G4. If a customer constantly travels with their PowerBook in a carry bag chances are the LCD will develop marks. This is typically a result of the leading edges of the keycaps rubbing up against the LCD. This rubbing is compounded whenever the PowerBook is squashed in a carry bag resulting in the top case and keyboard rubbing up against the LCD.

A good way to reduce the marks and potential abrasion whenever two surfaces meet is with the introduction of a cloth laid between the LCD and the top case and keyboard. A clever solution but make sure once again that the cloth used is not abrasive otherwise the cloth may become a contributor to LCD scratching.

Lastly never spray any cleaning agents directly onto the LCD. Always spray onto a cloth and then using a circular movement rub the cloth onto the LCD surface thus removing dirt and grime. Spraying directly onto the LCD surface may produce running.

Excluding the PowerBook G4 the exterior plastics and keyboards can be cleaned with the use of isopropyl alcohol. These wipes will clean away all unwanted dirt and grime and leaves a great finish without streaking. Also these wipes will not fade the screen printing on keyboard keycaps.

Before you give into your impulses and wipe your screen with whatever you have at hand, let us stop you right there. Your display is way more delicate than you think, and if you want it to last a long time in optimal conditions, you’ll need to treat it with proper love and care.

The good news is that cleaning a computer screen is more simple than you think. You only need a soft cloth, a tiny bit of water, and the most delicate of touches.

As you would expect, not all screens are created equal, and some are more delicate than others. The safest way to figure out the proper care for your screen is to search for the make and model of your device, find out if it has an LCD, LED, or some other type of display, and search for the manufacturer’s instructions on how to care for it.

If you want to skip all that, there’s an easy way to avoid making a mistake that might not only result in irreparable damage to your screen but to your entire device. According to Joe Silverman, owner of New York Computer Help, a tech repair center in New York City, no matter how much money you spent on your computer or tablet, it probably has an LED or an LCD screen if you bought it within the last three years—and neither type benefits from window cleaner or highly concentrated alcohol.

That’s the uppermost layer of your screen, which is extremely sensitive to the acidity in alcohol and in compounds like ammonia or propylene glycol. These are often present in cleaning agents such as window cleaners and degreasers. Using these liquids will corrode the surface of your screen, resulting in scratches or even smudges you won’t be able to get rid of.

Things get even trickier when you’re dealing with touchscreens. On models like the Microsoft Surface, the display is the main input—as opposed to your mouse or trackpad on a regular laptop—so it’s ultra-sensitive, Silverman says. Using a strong liquid cleaner like a degreaser or a bleach-based disinfectant can obliterate the top layer on the screen. Combine that with high pressure, and you can kiss your fancy touchscreen computer goodbye.

Another downside to newer computers is their size and weight. If you decided to splurge on a new laptop, for example, you probably found one that has top-notch components, but also a slick, lightweight design. This format is only possible if everything in your laptop is smaller and thinner. In the case of your display, a thinner screen means a weaker barrier between your computer’s guts and the elements in the outside world.

Caring for your screen is simple—it only takes a little bit of water and a dust-free cloth, such as a microfiber wipe or the piece of fabric that came with your glasses.

First, turn off your computer and disconnect the charger. This might sound paranoid, but the benefit is twofold—you avoid any chance of triggering an electrical surge, and your screen will remain black, which will make it easier to see any dirt and grime.

Pour a couple drops of water on your cloth. Forget paper towels or the sleeve of that soft cotton t-shirt you love—microfiber is your best bet. Still, no matter how soft it is, a dry wipe could always leave micro-abrasions on your screen. The moisture will also help gather dust and particles while lifting grease from your display.

Use circular motions starting in the center of your screen and moving outward, so you don’t leave any streaks. If you can see any droplets or water traces on the glass while you clean, you’ve used way too much water. Gently dab the residual H2O with an absorbent cloth or tissue paper and start again.

If you’re dealing with next-level gunk, you can use isopropyl alcohol at 70 percent or lower, Silverman says. “That percentage is very important,” he explains. “We’d only use 90 percent or higher on dummy parts that don’t have sensors, like top cases and keyboards.” In these extreme cases, spray the alcohol on the cloth, never directly on the screen, and wipe it gently.

Just like solar damage, screen damage is cumulative. The more pressure you apply, the more abrasive a product you use, and the more often you use it, the greater the damage you’re inflicting on the protective layer of your display and the delicate sensors underneath it.

Maybe you can get away with using a high percentage of alcohol or even a window cleaner on your computer screen once or twice. But if you keep at it, eventually you’ll see the deleterious effects.

“You’ll see discoloration, lines (vertical and horizontal); sometimes it looks pretty and rainbow-like,” Silverman says. “Sometimes it’ll blink and sometimes you’ll see droplets of water or liquid in the back of the screen. There’s a lot of ways in which damage appears.”

The best way to avoid damaging your screen while cleaning it is to simply keep it from getting dirty in the first place. If you have a laptop, cover the keyboard with a thin microfiber cloth before closing it to prevent finger grease from transferring to the screen. If you have a touchscreen, wash your hands often before you use it, but make sure you let your hands dry completely before you start tapping—the soapy water or liquid hand cleanser from your fingers can easily end up on the screen and corrode it.

Your phone was designed to be carried, dropped, tapped, swiped, smashed against your face for long periods of time, and stowed in the deepest corners of your bag. In other words, its screen is way more resilient than your computer’s.

Silverman explains that most iPhones and Samsung phones, for example, have screens made out of one thick piece of glass. These, as opposed to computer screens, have all the LCD layers fused together, making them much more difficult to damage. Still, if you’re using alcohol, he recommends keeping the concentration at 70 percent or lower, using a soft cloth, and applying only low pressure to get rid of any accumulated gunk there.

Replacing the screen of your computer or smartphone can be expensive, and even if that’s not an issue for you, no one wants their devices to fail when they need them the most. So remember these tips well—we hope you never have to read this article again.

Not to diminish what any of you are experiencing but every year the same things seem to be echoed. There will be people that say their phone shows scratches/nicks inexplicably and that there must be a defect because previous models did it do it. And that may be true for them but there is always at least one thread posted echoing the same complaint. Only thing that can be suggested besides the obvious (even though not loved by those that hate doing it...that’s using a screen protector of some sort and/or a case) would be to report it to Apple and determine if it’s really a defect or just bad luck. For those that are near an Apple store and feel like it’s a defect should go there and let them see the device and observe how the screen looks and then while there replicate the issue. If the screen is truly faulty it should be easy to make a new scratch/smudge/scrap appear if the only thing that caused it before was putting it into an empty pocket for example. Makes it difficult for them to not be willing to replace the device if you can show the issue happens. Probably not what anyone wants to hear but being able to show evidence absolutely helps more than showing damage after the fact and wanting them to believe the damage happened out of nowhere. Not saying any of you are lying but imagine how many people do or would claim scratches they know they created by being careless occurred out of nowhere.

I would be frustrated if it happened to me no doubt but I’ve been very fortunate. Never had a scratched screen or cracks on any iPhone. Yes I’ve dropped them countless times, tossed them with abandon, etc but I’ve also always used a screen protector (always cheap ones) and a case...usually an Otterbox Strada but I do so because I know that I always plan to sell my device and by taking these measures my iPhones have always looked like new making get top dollar (far more than any of these trade in offers ever give). Usually the first week or two has me using a cheap case to hold me over while I wait for the Strada or this time the Nomad folio to arrive while keeping a trimmed down version of the plastic that comes on the iPhone in place until my cheap $5.99 3 pack arrives from Amazon in place to keep the screen pretty safe. I say all of this to say that I have been pretty lucky to not have an issue on any of my iPhones or the others in my home (iPhone 11 product red and 2 iPhone 11 pro gold)...although I did have a mini scare when I dropped a thick heavy palette corner down directly on my iPhone 11 pro Max gouging the plastic and making me terrified that I had taken a chunk out of the screen. Thankfully no damage to the screen. No scratch or anything. That was pure luck because it absolutely should have had some significant damage if not a full fledge shatter. Definitely made me think long and hard about adding AppleCare+ immediately
