Water Spots on Windows

[srb1194]

Has anyone ever tried wet sanding windows to remove water spots? I'm considering trying this to see if it works.

Thanks,

That has bad idea written all over it.

Glass is much harder than paint, so getting the sanding marks out is extremely hard. UC or m105 works amazing with my PC. Just do that route and your windows will look great.

Definitely do not try to wet sand your glass.

Try some M04 and a rotary with a foamed wool pad or wool pad, or if you use foam, just be sure to check glass temp often as it will heat up quickly.

I have had a lot of success using #4 with my G110 and a 8207 pad.

I would suggest just trying whatever paint polish you have access to first (and by first, I mean don't try wetsanding...try different grades of polish). You'd be surprised how versatile products can be.

Thank God you asked first!

Thanks for all the replies. It just seemed to me that if rubbing compound worked that wet sanding would be successful also. I've tried the M4 and it does work but it seems that it is going to take a lot of effort to get all the water spots off. I'll give it another try.

Thanks again.

Have you tried claybarring the window? Sometimes that can be very effective in removing spotting.

Yes I have tried the clay bar method. Unfortunately it didn't work for me.

Try a mild acid wash. Acids break up the mineral stains by breaking the molecular bonds.

Even cleaning vinegar can work well, and won't harm paint. Get an old sheet and cut to roughly the shape of the glass. Dunk it in cleaning vinegar and lay it on the glass for as long as you can without it drying. Re-moisten if you like. Wipe off any liquid than runs onto the paint that may dry. Remove sheet. Then get a mild scouring sponge and scrub the glass. You should get most off with minimal effort.

if you think it takes a lot of work with m4 you couldnt imagine the PITA wet sanding would be lol.

Vinegar works on water spots. I tried it on a chrome bumper and the water spots came right off. Not sure what it might do to windows? I would assume it should be fine. Maybe try it in a small area and see what happens?

I've done it many times and it works fine.
