I have seen some pretty dirty windshields lately and am wondering what kind of cleaners are being used to wipe the ws clean before repair or after. which ones are good/which ones to stay away from? I know to stay away from silicone products, but is there any other bad chemicals to be aware of? So far, I have been using just a standard outdoor windex type cleaner from wall mart, and it just isn't doing the trick.

Thanks!
