I am EXTREMELY particular about having clean windows in my car. I noticed under the right light sometimes at night that there is small traces of overspray on the windows from when it was at the body shop.

Is it safe to put paint thinner on a rag and wipe it down?

 

clay was developed for exactly that- removing paint overspray. i use it on glass all the time for contamination removal...

check it out and let us know what you think. i will be shocked if it isnt the 100% solution

 

Razor blades also work well on windows

 

Or very fine steel wool

 

Second vote for the clay. It is remarkable for removing contaminants from glass and plastic.

 

Sorry I did'nt get back to you guys earlier. The clay worked, and worked well. My windows are clean once again. Thanks guys. I'll post pics of my car soon, in hope of obtaining a badge.
