Gary has a posting in his website using Denatured Alcohol and water, using that on Rain-X, I found that it clouds up. Gary suggested using Simple Green to see how it would come out, about the same. I then used 100% Ammonia followed with washing with dish soap. That did the trick, although there is still some Rain-X on the glass. The wipers never had hesitated on the Rain-X[.:I] I never would apply it on a windshield again [xx(]. knowyourturbo: The best bet would be to "happen to chip or crack" your windshield and get a new one
