Cleaning overspray from paint booth light glass covers

I recently built paint booth and was able to find 22 4 foot paint booth lights from a large truck painting business that closed down. They are commercial lights of good quality with glass 4 foot coverings. They are loaded with overspray and I have been trying to clean the paint from the glass and its very time consuming. I have been spraying on lacquer and using a razor blade but its taking forever. Is there a better product out there for cleaning overspray? Maybe some type of acid that would lift the paint without damaging the glass. I tried searching here but didn't come up with anything. Thanks Paul

A razor blade is the only thing that I've ever used. Do it dry. Use a good holder and change them out fairly often. Push down fairly hard, make a pass without stopping. Should be able to do each piece of glass in 10 minutes or less.

This type of holder works pretty good.

Just to add to what I said above, once you find the right angle to hold the razor blade the overspray will come off pretty easily. FInd the right angle, and push the blade like it's a snow plow. The overspray will come off easily then.

home depot you can get a razor scraper with a 4" wide blade for about 5 bucks and comes with a pack of blades. they sell extra blade packs as well. usually in the paint asile. these work great for the glass. the one chris posted will surely work fine. it will just take alot more passes.
 
when I got my booth used I had terrible glass too. Ended up with McMaster carr 7764T21 methelene chloride paint stripper. I dont really think overspray is a good word for what you have if its what I had. They sell it at home centers as well.
What helps with a razor cleanup is invisible glass cleaner when you get to the point of really only having overspray on them later.

Good to know Jim. I had no idea there were 4" razor blades. :)

This part american indian guy I worked with years ago always kept a leather belt around to draw razors over when they got dull. definitely good for the wider ones, that are at least twice as thick and dont stay sharp long. Almost like the final polish of a knife blade. Same guy that taught me the worst thunderstorms and tornados show when the leaves on the trees go upside down.
