Our brand new (well, two years old now...) dinghy is looking a little dingy.

Does anyone have any suggestions for cleaning a hypalon dinghy? Will
bleach hurt the hypalon?

Note that cleaning materials that work on PVC (or decitrex) may harm
Hypalon and vice versa. I am interested in hypalon cleaners...

Also note that I have been specifically advised to avoid cleaners which
contain silicones (eg ArmorAll) to minimize problems with future patches
