I am looking for a way to remove hard water / acid rain spots from the t-tops and rear window of my formula. I have tried eastwoods diamondite glass kit an it didn't seem to help, cleaned the glass good but left the spots. What should I try next?

 

I use a razor blade. Its a pain in the ***

 

white vinegar, use it sparingly with a rag.

 

at work I use a razor blade to start. Then if I need some general rubbing compound that works too with some hand buffing. Don't get to crazy though, don't wanna scratch the glass. If the acid spots are really that bad, then the cars are taken to an off-lot vendor for an acid wash treatment. This is similar to the vinegar effect, except with industrial chemicals. So you have a few different options here, choose what you think may work best for the type of spotting you have.

i used lighter fluid and it worked like magic

 

lighter fluid is the cure for everything! plus it dries to nothing.

Zaino glass polish, love it.

 

Razor blade here tooooo!....

 

several good options listed above.

depending on how stubborn they are, I will use:

clay bar
vinegar
razor blade
buffer with a wool pad and some light compound
000 steel wool
barkeeps buddy (DO NOT GET IT ON THE PAINT)

just be safe, and protect your paint from any chemicals you end up using.

 

i tryed the zaino glass stuff by hand and with my pc with a whit pad and it still dident come out. maybe ill try the vinegar and lighter fluid and see what works. **** is agravateing when the car is cleaned up.

 

I want to say thanks guys for all the feedback. I can finally get this taken care of.
