Best way to clean paint off of a windshield.

Try NON Acetone nail polish remover. If it fogs the clear part brush some Future over it to make it clear again.  

If it was futured already, you should be able to remove it with windex. You will have to re-future it though, since the windex will remove the future.

Windex will not remove enamels as far as I know. 

Hartmann352, have your friend buy a can of the yellow Easy-Off oven cleaner. 

The reason I say, "yellow" is because it is the original formula. The other one that says, "no fumes" does not work near as well.

Spray it on the windshield and put it into a zip lock baggie for a few hours and respray if necessary. Use a soft toothbrush and scrub the old paint off the windshield and rinse well with water.

The reason I believe windex will work is because he said the windshield had already been futured. If that was the case, the windex will remove the future and the enamel paint which is just sitting on the future without harming the plastic. I could be wrong, but it seems logical. Besides, oven cleaner costs money, and I'm cheap!

Alcohol will remove Future, enamel, lacquer and latex paint.  No need to use caustic chemicals like Easy Off.

You can soak the part or use a cloth dipped in alcohol and rub on the paint, it will eventually remove the paint.

I accidentally got some Model Master enamel on a P-51 canopy which I had Futured a few days before.  I just took a napkin dipped in good ol' mineral spirits and wiped the paint clean off.  A little washing with some dish soap and the canopy was back to sparkling again.
