I have removed bootheel rubbers and plastics from exhaust pipes with steel wool, in the 0000 (four ought) grade. It takes some elbow grease, so it helps if you warm up the pipes a bit first. I'd recommend wearing some heavy welding gloves while you do this.
It's what they use at the local Harley dealership to polish chrome all the time. (I have a buddy who was a detailer for them for a while.)
By the way, this also works great on aluminum and stainless to repolish it. Don't use it on brushed, though, or you'll have to do the whole piece and turn it polished. If you're really pedantic, you might wish to use stainless steel wool on your stainless steels. It's what I use on the TIG stuff at work to make it all nice and shiny.
