one thing I ALWAYS do now, is when putting the top down... stop mid-way & pull the top fabric out of the scissor-joint. This way, it won't get pinched & leave cuts in your top. Also makes for a slightly lower stack height for the top as well. As for cleaning, I've heard from multiple sources to NEVER use bleach, bleach-water, tire bleach, etc. on the vinyl tops as is weakens the threads & fabric. Have tried several supposed cleaners... Meguiar's vinyl cleaner works pretty good. Just picked up some RaggTopp vinyl top cleaner... will see if it is any better. Unfortunately, I have a WHITE convertible top- which is just about the worst to keep looking good.
