OK yall, today I got lazy, the track was nasty and I didn't wash the bike after the previous ride (crzy work schedule, blah...). So I rinsed off the chunks, soaked it with simple green, waited about 5 minutes and hosed it off. That stuff is like magic! OK now the question; it works so well, I'm concerned that it might hurt the finish of the shiny metal parts over time. You guys who use it all the time, have you noticed that it pits or tarnishes the metal after a while, or takes the nice finish away?
