Hiya - what's the best product/method to use to clean me roof top? It's got lots of white marks on it and could do with a good clean but I don't want to end up with it looking worse than when I started!!!

Any tips gratefully received. :)

I like Meguiar's C0NVERTIBLE TOP CLEANER.:cool:

I used the Autoglym (http://www.autoglym.com/enGB/product-proddetail.asp?v06VQ=GG)cleaning kit, It's a 2 part kit (shampoo and waterproofer) with a special scrubbing sponge.

The water now beads on the fabric so I'm happy!
