Hi all, my dealer applied aquapel to my windshield and lets just say it was applied bad..when wipers in use its like a cloudy smear. I tried to clean windshield and it seems that there might be residue of past use of rain x in washer fluid tank not helping things. I was going to fill my washer flyid tank with a degreaser and let sit a few days but not sure its safe for the paint..can anyone recommend a cheap , easy and safe way to remove any greasy waterproof stuff out of washer fluid tank? I am going to try a glass polish aftwr i try a degreaser on the windshield. Glass cleaners have not helped...
