I have been hand washing my Ssr rowdy for over a year with just car wash soap in a bucket and it has been fine. Unfortunately my neighbour let me try a product called S100 motorcycle wash and it stripped the gloss right off all the black tubes on the bike. It did some damage to his old s50 1400 paint he has as well. We washed the bikes right after it rained and my bike was cool from sitting in the garage. I bet the stuff didn't even sit on it for over a minute before we rinsed them off. I'm Really bummed out the bike it has Damn near looked new for a while even with the sun beating on it. I waxed it pretty good on every painted part this summer and It didn't hurt the paint on the plastics but destroyed the finish on every tube on it. Wax did not seem to bring back any of the luster either. It's like a flat black on the tubes now. Crying shame.
