Re: Cleaning/polishing exhaust tips. I posted this previously will post it again if people are on an exhaust tip cleaning kick... This stuff is MAGIC. Primarily made for cleaning gun residue that no solvent or anything can cut through, with this you just wipe it away in a few seconds. Cut a 2" x 3" piece and done in couple minutes. The 6" x 9" sheet gives enough for 9 cleanings so $1 per.
