Just wondered, have used this for years. Very good at removing the carbon and “soot”. I just use paper towels. Did mine today, I do the outside also but not with the alcohol. Wanted them to go out pretty. Will have a F.I. CB in a few weeks.

 

I use Never Dull to do the same. Also works well.

 

I heard it works good mostly with titanium exhaust tips, otherwise i use any kind of metal polish, I like the griots ceramic metal polish cause its easy to apply and distribute
