I have a Yellow 02 stang with a white top. I have tried EVERYTHING to get this top clean on my car...these stains have been around since when I bought my car (i bought it a year old). I have tried the Ford "3 in 1 cleaner" made for the tops, with a nylon scrub brush, it works ok but not great. I have tried a few other convertable top cleaners, but none do a very good job, and this looks pretty bad, I think. I know a guy who has a tan top 99, and he had a water leak which caused mildew from the interor....needed a new top! Any ideas on what to try and clean this with?!?!?!?!???? Since I don't have a leak, would this be a manufacturer defect or just a Florida thing with high humidity?
