I know I have to wash and scrub but I've tried several things and don't seem to work. I tried regular soap and scrubbing like a mofo, it helped a little bit but nothing major. I also tried that convertible top cleaner from O'Reiley and nothing. So what do you recommend to get my once black top, black again. Oh, and it's in excellent condition so I know it's not too old. It's just plain dirty. 
Helllllp!
. this might be a stupid question but where can i get a LINT free towel, autozone. all the towels i've seen have lint
