I had a plastic shopping bag blow across the highway and wrap around the pipes on Wendy's bike. I ran the engine until the pipes were good and hot and wiped off what I could with a clean soft rag. Then I polished the rest off with Blueaway. Worked well and was fairly fast.

I learned all I need to know about life by killing smart people and eating their brains.
Eat right ,Exercise ,Stay fit, Die Anyway!
