Well I went to Boater's World and bought two bottles at $10.79 a piece. The stuff did nothing. I mean nothing. Water would have been just as good. Did not take off dirt or mildew. Did not even take off a couple of bird droppings. Don't buy this. I plan to return both the used and unsed bottles. Incredible; seemed to do nothing. I was just going to use Tide soap powder but Sunbrella says to use only "natural soap" what ever that is. What a waste of time.
What do you guys use?
