I've been using it for many years. I never had any issues on my black bike or the engine. I always wash it in the shade. I also rinse it off quickly & shammy it before it sets too long. Just my 2 cents.

:icon_that: Don't get the issues as long as you do as above.

Sounds like you used it per the instructions, and it worked great. Amazinghow ythat work, huh?

I used it on my old bike and it gave me these little brown dots on my handle bars. I tossed the bottle in trash after that!!!!
