My car has wipers?
I agree with Randall. "Forgive me Father for I have sinned, it has been many months since my last confession"!
Clean your windshield with 1 part denatured alcohol and 2 parts distilled water, mixed in a spray bottle. Spray a 100% white terry cloth towel till very wet, scrub windshield, and then buff dry with anther white 100% terry cloth towel.
