So I've been working on the wife's Explorer for a little bit now. It does have the 3.5L Ecoboost which I've heard is pretty notorious for this but the exhaust tips are horrendous. They were originally polished stainless and when we bought it were completely matte black from carbon (not paint). Since then I've made HUGE improvements with a couple degreaserings followed by chrome polish. I used a wool applicator on my cordless drill, which has been my go-to for other similar tasks. Overall, again, huge progress but it seems I have plateaued. For the most part they look pretty decent, but there are a couple of very heavy, solid and thick sections of baked on carbon remaining.
Further polishing does not seem to touch this. Nev-R-Dull does nothing. Turtlewax chrome polish doesn't yield further results. Meguiars chrome polish also has hit the plateau. I've a little hesitant to go with a true abrasive. My only other thoughts would be to look at some gun products designed for carbon fouling.
