I've heard Easy-off oven cleaner works pretty good.

Scrape it off with a wooden paint stirring stick when the pipes are hot, then after they cool use some Mothers chrome polish to clean the remaining streaks.
I'm thinking about making a small metal guard and attaching it to the floorboard so my boot won't hit the pipe.
