That S100 Total Cycle Cleaner is some caustic chit. If you don't get it all off and out of every nook and cranny, it'll leave a white residue that is pure he!! to remove. Not for me. I've never used it on my SEUC. I learned my lesson with that stuff on my old softail back in 2003. Took me all summer to get that chit off my bike, and that was after following the directions and COMPLETELY and thoroughly rinsing the machine. So.............today I use Harley sunwash to wash the bike, and Harley wheel and tire cleaner for those areas. Ammonia free windex on the powdercoated engine, transmission, primary areas, Glare products and plenty of microfiber cloths. It takes me about one 12 pack of Yuengling Light and copious amounts of Sirius Channel 14 Classic Vinyl to get through a complete cleaning, but she sure looks schweeeeeeet when I get finished.
