Title: Water spots?
Post by: GTRS Fiero on August 12, 2018, 08:58:20 pm
I used the hose to help get rid of the airborne memorabilia from Illinois that were plastered all over my Fiero.  Unfortunately, there are now water slots on the car.  I have been unable to remove these dark spots from any surface.  The spots are most notable on the side mirrors, but the glass has spots also, and the body, as well.

Any ideas to remove these blemishes?

Clay bar.  Lots of elbow grease applied to a Clay Bar.

On glass, plexiglass, and paint?

I can't speak to the plexiglass, but it's designed for paint.  Can't hurt glass I think.

I'm mostly worried about the glass and the plexiglass.

By Plexiglass, I suppose those are the quarter windows?  Not much you can do to them without really making it worse.  Do not use anything that has a petroleum base on them.  No wax as many contain aliphatic naptha or mineral spirits.  Almost anything you use on them to buff and polish will leave marks.  That is a cast surface.  It is poured onto a flat plane as a liquid then I believe it's run through mirror-polished rollers to bring it down to a thickness and put the finish on it while it's still pliable.

Hmmm.  I used water and Windex, with a chamois cloth.

After about 2 hours of polishing, the left side mirror is almost free of water spots.   I'll work on it more later.

Don't use ammoniated glass cleaner on the quarter windows.

Hmmm.  I wonder what's in Windex and windshield washer fluid.

Sometimes they contain alcohol.  Helps evaporation and drying.  My jug of windshield wash says it has butoxyethanol.  I suppose that's a form of ethanol alcohol. 

I use a glass cleaner made for the graphic arts industry when I hand clean windows.  Made by Sprayway.  They have several versions.  The blue can is the proper one.  No ammonia.  No streaks.  No residue.  Safe for factory tints.  Not for aftermarket tint or non-glass tv's, computers or mobile devices.  It's available in some grocery stores.
