I recently bought a 2001 Miata SE (Special Edition), in good shape, except for a number of items that need detailing. Item #1 is the convertible top, a special tan vinyl that is texturized (lightly pebbled) to look like cloth.
It was pretty dirty, and a thorough cleaning with 303 did most of the job. However, the top has some spots which look like grease and won't come out. These stains were apparently picked up from some thick gunk that accumulated under the frame rail that runs behind the rear window (the top would brush against the gunk when it was folded down). I've removed the worst of the gunk, so it won't be causing new stains. As I said, I've treated the existing stains with 303 (and also RaggTop, for good measure). Left both to sit for 15 minutes, agitated with a soft brush, basically nothing happened. (I also tried scrubbing a small stained area treated with 303 with a soft toothbrush, just to see what happened with a little more elbow grease, and the result wasn't good -- it was definitely going to cause scratching if I continued.)
Any suggestions for how to proceed would be greatly appreciated. Assuming this isn't hopeless, It almost seems that I need something like a vinyl cleaner with a soft abrasive, if there is such a thing.
