I picked up 0000 at Home Depot. I'm not sure how close fine is to 0000.

i tried car shampoo (SONAX) on another car that i have with supersprint muffler box it did good, then i coated it with the wheel wax, i drove for 3 hrs straight, stopped and with a bottle of water and tissue i had it cleaned again (no effort).
Point is: WAX IT regularly .

Is this after you had a very dirty inside pipe? I'm talking years of soot that's never been removed.

FWIW, I recently tried cleaning out my exhaust tips on my 328i. CPO with 37,000 miles. Looked like it was never cleaned. I got Mother's Mag /aluminum polish, took out the dremel with the polishing white fabric tips, and went at it. 30 minutes later.... any shiny spot on the exhaust looked great, but it couldn't lift the "years of soot that's never been removed." I still have yet to tackle that. I'm sure steel wool or something will remove it, or if I used one of the more aggressive polishing wheels in my sanding/polishing kit. But I haven't yet. I can just say that however much you try by hand, you can't get that grunge off with the mag/alum polish (fine, you could, but it would take hours/days of vigorous rubbing. Who has time for that?).

Wheel cleaner + brush to remove most if not all of the carbon deposit.
Megs power ball + metal polish to remove the rest and polish it to a shine. Leaves a protectant coat too.

I do this weekly, so no. If you have soot caked on you'll need something to break it up first. I've used a little bit of brake cleaner on a sponge before and it worked well.

Thanks for many good suggestions. What just worked best for me was a combination of brillo pads, brass brush, water, simple green, engine cleaner, flat top stove cleaner, and some elbow grease. Probably six years of carbon build-up on our Acura RDX.

Red scotch bright.

I do the tips last and just dip the pad in the soap bucket. Gets the black off super easy.

My favorite for exhaust tips is P21S polishing soap. 0000 steel wool or a brass brush if you really need it. Bought my car CPO and it took a handful of scrubbing sessions (made a little progress each time I washed the car) to get through the layer of buildup on the right exhaust tip, but now it's really easy to maintain. I also recommend Wolfgang metal sealant once you get it clean.

I have the M sport exhaust right now with stainless tips and I find that the soot doesn't just build up inside the pipe but also accumulates on the outside of the rim of the pipe.

I use 0000 and 000 steel wool. The 000 only on the inside and the 0000 on the outside. I use more pressure inside the pipe than outside the pipe. On the outside I find if you just press the 0000 against the build-up and keep going back and forth over it, it will eventually go away.

I am upgrading to the Dinan exhaust with black tips in a few weeks, and even though it will be black I still want to keep it clean. I am not sure I want to use steel wool at all on the black finish though because I think that if it scratched or mars it at all it'll be noticeable, so hopefully I can find a liquid cleaner that will work with a rag.

I used a dremel with a wire brush, then used the dremel to polish the lip of my exhaust tips. I touch it up with metal polish every few washes. Has worked great. I don't fuss with the inside of the tip much though, too much work
