On the slotted tips on the 71/72 B bodies, I was wondering what would be a good cleaner to keep the inside orange part clean. Something that can cut the carbon build up.

Probably not what you want to hear but I don’t even try. I prefer mine to be a little carboned up. Tones down the bright orange/red.

Why are you getting build-up on the inserts???


I eliminated the 'flange' internally up at the front of the slots that gets eaten-up over time on the OEM tips...


After 20 years of road time, nothing on mine other than some occasional 'dust', which hoses right off when I wash the car...



For clean-up, scrubbing bubbles, or some spray household de-greaser...


I use Nev-R-Dull on the chrome...

No, I meant on the inside where the exhaust come through, it is Orange also.

My car has build up on the inside as well as the outside of the orange painted insert. This is from years of driving before I bought the car. Have yet to find anything that easily takes it off.
