I have two sibs, one is a Prowave 320 Airdeck, fantastic boat and is in mint condition, after each use i clean it, dry it and put it back in the bag.
My other boat is a cheap round tail boat which i bought of ebay brand new for 80 quid and its a Navigator III 400.
My dad wants to start using this boat, i got it out the loft and it is in a state!
Covered in marks wich i cannot get off.
I thinks its a PVC any ideas of how to remove stains and generally clean.
