TOP cleaning?!

[Ronzi]

Raggtopp also has a Fabric and Vinyl Cleaner, as well as the preservative. It seemed to do a good job on my top, although I have only used it once.
That product may not be available in Poland, however. Porsche dealers should also carry a top cleaner and preservative, since the owner's manual advises getting those products from their dealers.

I used the raggtop cleaner and sealer and I thouth they worked great. Make sure you take the time to mask off your rear window if it's plastic. The protectant might never come off from where I got a little overspray. It won't ruin your window but you'll notice it, trust me.
