HI! Does anyone know how to remove deep scratches from clear parts? I know one technique by using sandpapers but I find it kinda risky. Are there any other ways to remove it?

You can try a bit of polishing material. I use an aluminum polish. Its a very fine paste that you buff on and rub out scratches.
If they are really deep scratches you can to fill them with future floor polish and then buff that. I've never tried this but that's what I would try.

Scott,

what is this Aluminum polish? is it like Turtlewax?

Shonen, There is a product called Blue Magic that works well for buffing out scratches. I'm afraid though that if they are deep scratches, you are going to have to resort to using the sandpapers first. If you check on Micromark.com you can find a polishing system that has varying degrees of sand paper in it. The set I have goes all the way to 12,000 grit which is about as smooth as glass...to me anyway. Using this in conjunction with the Blue Magic or even Novus Plastic Polish will get you the results you are after. It takes time though. HTH. "Q"

Try buffing the glass with toothpaste if the scratches are not too deep.

You'll have to go over to the dark side at the hobby store and look inth automotive section. Look for a set of polishing pads. Shuld be under $10. These are foam backed and start at 1600 or so grit and go up to 32000 grit (IIRC). Buck up and start withthe 1600 and buff everything donwn to one level. Use the next higher grit and continue. You get real scared at the first level because the glazing WILL become all frosty. With each successive pad, the frostiness gets clearer. By the time you get through with the l;ast one, the glazing will be better than it came out of the box.
Are they safe for the surface? Remember, these are the pads the car guys use to get thise absolutely shiny smooth finishes on their stuff. I've used them in both applications and they are great.

To add to what Al said i use them when i buff my cars gloss finish they work great you can also get the Novus polishing system it has a heavy and fine scratch remover and a plastic polish great to use when you are done sanding with the pads you can get them from mircomark.com

Hi,
I used to polish it with car polish or toothpaste. It just works on not too deep scratches however.
You can also try water sandpaper for car body. But don't forget to wet the paper.

Hey Ralph you can also dip your glass in to a acrylic floor wax. Furture, Johnson's are just a couple to name. I'm sure you've seen it, it's clear. You just dip it in and lay it down onto wax paper. Depending on how deep your scratch is, you may have to repete a few times. This stuff also drys fast. Another thing with using this stuff is that it also make looking through the glass much clearier and less distorted.
