    Default Polishing plastics

    Hello,

    I have read some things about polishing plastics here but have a specific question about polishing a laptop screen. This is on an old laptop, not touchscreen. It has some light scratches on the display from the keys touching it while going down the road in a 5th wheel.

    I recall someone saying that toothpaste will polish plastic. Will it work on a laptop screen.

    Also have some sunglasses with small rub spots on the lenses. Not scratches but spots where something rubbed against the lenses and marred the surface.

    I thought about just trying it but decided to check here first.

    Thanks for any advice on this.

    There is typically an anti-glare coating (though not always). Is the coating still present? Is the damage just to the coating? Wondering if you could just remove the coating if present and be done.

    It would polish each of those, but it also may remove any coatings.

    I'm going to try it on a corner of the screen and see what happens. This laptop is about 8 years old and doesn't seem to have much of an anti glare coating.

    Are the scratches on the laptop screen visible when the display is on?

    Mostly just when there is light glaring on it from the window behind me.

    Your local autoparts store has everything needed to restore plastic to optical clarity. Toothpaste is too coarse. 1200-2000-3000 grit silicon carbide paper to remove scratches and then finishing with plastic polishing liquid on a sponge will make it look like new. 3M and Meguiars both have it covered.

    There is a product called Novus, a 3 part kit, less than $10 on eBay. Specifically for polishing out scratches in plastic.
    Works perfectly!

    I use Mother's Plastic Polish for that sort of thing. It actually polishes, unlike toothpaste or other home remedies. Find it at your local auto parts store.

    I tried the toothpaste on a lower corner of the laptop and it appeared to clean it pretty well so I did the whole display. I'm amazed at how much better it is. The worst marring is still visible but not as bad as it was and the rest of the display looks like new. I'm not sure how much to go after the marring that is still there. I don't want to wreck it by pressing too hard.

    There is a little bit of micro scratching if I hold it in the sun at just the right/wrong angle. It isn't noticeable when I'm using it. I may order some of the Novus stuff and try that too.

    Thanks for the advice guys.
