cleaning a really dirty windshield

[roho]

This is a pretty old thread but I got a fix for overspray on windshield! Walk over to welding shop where overspray came from and ask for a clear plastic welding hood lens, it's a protective lens to cover the shaded lens! All welders have them! Anyway just scrap the edge on the windshield and the overspray will come off and as far as the overspray on the car paint, a fine compound that is bought at any auto part supply store or department will get rid of the overspray! BUT if YOU were parked in lawful parking space YOU may ask, & I mean ASK the welding shop to have it done for YOU! They have or should have insurance for this type of ACCIDENT!

I have cleaned a few windshields of overspray and use lacquer thinner on a rag. It takes the overspray off. When done use windex or similar to final clean. No scraping involved. Be careful not to drip on paint finish.

I'd run it thru the car wash, (not a touchless car wash). Careful with the paint thinner and acetone, if you spill any on the car you'll be sorry.

And when you are done getting the overspray off, put RainX on the windshield. If you use it on a regular basis, nothing will ever stick to it again. I love the stuff....

The safest way to remove overspray is to use a claybar. Go to Autozone or any good auto supply store and buy a claybar system made by Mequiers or Mothers. It consists of a piece of clay and a bottle of spray detailer used as a lubricant. Wash the car and dry. Spray the detailer on a small area and rub the clay over the surface in a back and forth motion, not in circles. Wipe off the residue and continue over the rest of the car, windshield included. When finished apply a good wax. Not as hard as it sounds and really produces a smooth finish. Just use plenty of spray detailer as you rub the clay over the paint.

Love the RainX. And we get our fair share in the Pacific NW.

Another trick to try is to use a much less abrasive version of Comet that is used for cleaning kitchens. It's called Bar Keepers Friend and when mixed with a bit of water forms a nice low-abrasive paste that works wonders.
