I have a 2000 F-150 extended cab and where the rear windows are the bottoms let water run in streaks down them and have caused stains. Now for rockpicks reference I would say class 2 stain etched in the paint. What is the best thing to use on it to remove these stains.

Thanks for input.

 

have you attempted to dilute some normal white vinegar with water, put in a spray bottle, spray let sit for 10 sec. wipe off?

im no detail genius, so others may have more suggestions, but thats what i use (in either a 1 part vin. 2 part water, or 50/50 dilution) for all of my water spot problems- works great...
