A couple of weeks ago I used Oxyclean and that stuff really works. From what I can find it is pretty harmless. I was able to spray it on and wipe with a soft scrub sponge. It took very little scrubbing mostly just wiping. It took off some stains I couldn't get rid of before. I was able to wipe down the cockpit in just a few minutes. At the time I was a little apprehensive about what was in it so I rinsed the boat well after using it. Found out later that there is no need to rinse.
