I used on/off tonight on my boat and that got the crud stain off the boat, but did not budge the green growth & barnacles.

I then hooked up my new 4 hp Craftsman 2150PSI gas pressure washer. Wow!!!! It knocked all of the garbage off like nothing. What a tool. the only thing is that you have to be careful where you aim it. I have read that it will split cloth wide open, as well as skin. Cool tool, though
