What would any of you recommend for cleaning very dirty & stained exhaust tips?

My car does not have catalytic converters. I didn't bother cleaning the tips for months and now it almost seems impossible to get them cleaned. I have tried scrubbing down the inner walls of the tips with no avail

This is how they're SUPPOSED to look:

I've used this on my exhaust tips as well. Seems to help, although the difference was not as drastic.

 

Wash it let the soap soak a lil, then maybe a gunk/wd40, then some metal polish, if not some very high frit sand paper!!!

 

try a lil #0000 steel wool and metal polish. should do the trick unless they are really dirty,

 

Mothers billet works very well.

 

+1 as i have used this method and it works quite well.

 

So I decided to give BlueMagic a try, and it worked like a charm!

Keep in mind that my exhaust doesn't have any catalytic converters and the exhaust was stained from months of not being cleaned.

This is what 5 minutes of soap/water + brush scrubing accomplished:


This is what 2 minutes of a quick cleaning did with the BlueMagic polish with nothing more than a rag:


I didn't finish it up since I was just trying out the product and it was already dark though

 

Start with 000 steel wool, clean it with soap and water, then wet sand with 3000 grit sand paper. Then polish with an aluminum polish or braso.
