Been there, done this........with a melted car cover on both sides during a sudden rain storm, that blew down over hot pipes.

For ceramic sidepipes, #0000 steel wool, and a green Scotchbrite pad will remove all traces. Use a bucket of clean water, and keep soaking both. Start with the Scotchbrite and finish with the steel wool. Use as little pressure as necessary. No chemicals are necessary. A light brush with the 0000 up and down beyond the residue area will blend in and clean up the rest of the pipes.

It helps if you drive at least 100 or more miles first to burn off as much of the residue as possible. Then, it's a fairly easy clean up.
