i had my muffler removed and a straight pipe welded in, but i had the tips welded up a bit too high, so now some of the carbon from the exhaust is building up on the body. will this come off with just a good soapy rag, or do i have to polish it off? i want to replace my bumper sometime in the future because it was hit and has a hole in it and the paint came off, but i still want it to look good

 

It'll wipe off.

 

Why don't you try, then you will know for sure. LOL

 

because i tried wiping it off with my coat sleeve, but it felt hard and crusty and took some effort to get off

 

try using an old rag or something,something your not affraid of getting dirty
