dude the only way to go is raggtop cleaner and protectant. The stuff is very easy to use and is the best stuff out there. they offer a kit for like 30 bucks it includes both the cleaner and protectant. I have a black top. When i got my car it had come up from texas and i dont thing the top had ever been cleaned or protected because it wasnt black nemore, it was red. I used this stuff and it brought it right back to black and prtotects it very well. I stand very strongly behing raggtop.
