Just passing on a tip that really works!!
The new boat was finally starting to get yellow on the bottom. Plus I had some rust stains.
I tried a few cleaners, but then I remembered I bought some hull cleaner / stain remover from Vyper 340.
Best Hull/Stains Cleaner! Easy to Use
This stuff is like a gel, I put it on a sponge and smeared it on the hull. The yellow was gone. I didn't need gloves, googles or a resperator. Plus the wax appeared to still be there; the water still beaded.
I then tried it on some really stubborn rust stains. . . . 2 or 3 minutes later; GONE!
I've used it in the bilge and hull of my old boat, but completly forgot how good it was. (Plus it was too easy to go to boater world and buy some on/off. . . never again!)
This is the best stuff I've ever used!!!!!
BTW: Vyper 340, send me another bottle. I want to make sure I always have some!
