I rub acetone on the stains on my white 08. I probably wouldnt do it if you are real anal about your bike, but it takes 90% of the stain out. The only side effect i see is that it dulls the shine a little, so I wax that spot and it turns out good. The sun shine also takes allot of stains out...I'm not kidding. I had a stain that wouldnt come out, and within a few days of riding in the sun, it was gone, I swear. If you wanna try the acetone, just try it under the fender or somewhere you wont see it, just in case.
