The short answer
Degrease the tip first, then use a metal polish with a fine abrasive and real physical effort, working in one direction. Soot bonded by heat cycling does not wipe away, and no soap will remove it.
For chrome trim elsewhere on the car, the enemy is different: it is water spotting and pitting, and the answer is a mild polish plus a sealant to keep moisture off the surface.
Exhaust tips, step by step
- 1Work on cold exhaust. This should not need saying, and it does.
- 2Degrease inside and out with an all-purpose cleaner and a brush to remove loose soot and oil.
- 3Rinse and dry, then apply a metal polish to a microfiber or a polishing pad.
- 4Work the polish in straight passes, refolding to a clean face as it turns black.
- 5Repeat until the transfer slows, then buff with a clean towel.
- 6Seal the finish so the next round of soot sits on protection.
What to use on what
| Finish | Use | Avoid |
|---|---|---|
| Chrome exhaust tips | Metal polish and effort, then a sealant | Steel wool, which scratches |
| Stainless tips | Metal polish, slightly more forgiving | Coarse abrasives |
| Black chrome or PVD | pH-neutral cleaner only | Any polish, which removes the finish |
| Chrome body trim | Mild polish plus sealant | Acidic wheel cleaners |
| Anodized or painted trim | Soap and water | Polish and acids |
Metal finishes and safe products
Polished tips are part of the exterior detail
Exhaust tips are polished as part of the Exterior Detail, along with trim restoration and wheel barrels, from $99.
Black tips and coated finishes
Black chrome, PVD, and ceramic-coated tips are not polished, ever. The color is a thin surface treatment and abrasive polish removes it, leaving a patchy mess that cannot be undone.
Those get cleaned with a pH-neutral cleaner and a soft brush only. If yours are black from the factory rather than from soot, this is the difference that matters.
Keeping them clean once they are polished
Polishing is the hard part. Keeping the result is easy and almost nobody does it, which is why tips look black again within a month.
- Seal the tips after polishing, with a metal sealant or the same sealant used on the paint.
- Wipe them at every wash while the residue is still soft, before it heat-cycles onto the metal.
- Do the tips last so the polish residue does not transfer onto clean paint.
- Keep a dedicated towel for exhaust work and never let it near paint or glass.
Chrome trim on the body, which fails differently
Body chrome does not go black from soot; it pits from moisture, road salt film, and acidic contaminants that sit on it. Pitting is corrosion under the plating, and no polish reverses it once it starts.
Prevention is the whole strategy: clean it regularly, dry it rather than letting hard water evaporate on it, keep acidic wheel cleaners away from it, and apply a sealant or wax so contaminants sit on protection rather than on the plating.
