I dont know if this would be the right forum, but what do u guys think is the best way to remove the black deposit on the tip of an exhaust i have...it has a deposit from runnin on a turbo car that ran really rich...also what do u think i can use to polish it..

 

You could try wire wheel acid to get the deposit off. Is it a stainless steel muffler? If so maybe try a chrome polish, should work.

 

yup stainless steel..thanks
