Cleaning your exhaust pipe ends?

I have a 335xi, just wondering if anyone has a good method of cleaning the soot from the ends and also what a good product may be to shine them up?

I used eagle 1's polishing wad. First cleaned it with dish soap and then hit it with the wad. Its does an amazing job. Best part, find it at walmart. A little of the wad goes a very long way

It really is. You can read up all you want about how to please a woman, you can look at all the diagrams in the world, but just like the clitoris, you won't know what the hell an apex is before you actually find it.

simple green and a crappy rag should do the trick, for baked on problems, use a brass brush and it'll be sparkling like new.

I also use P21s polishing soap and it does a good job. I never put in the elbow grease to get them 100% clean, and some people say to use #0000 steel wool on the insides to really get them spotless. But my car isn't a Concours winner

if i had a dollar for every one of these threads. Best way to get them spotless: purchase a new catback and replace and BAM! New tips ^_^

simple green and scoth-brite pad works for me. Just a timely procedure for something that is going to turn black the second i step on it

The tips can usually be cleaned with a good metal polish (ie P21S Finish Restorer). Just wipe it on with medium pressure and a soft cloth and it should have an incredible shine. I use the metal polish to spot treat areas on my wheels and trim. We have an article on taking care of them as well here http://www.detailedimage.com/Ask-a-P...tip-detailing/!

dont waste your money on these products. I use Blue magic polish which is around 4 bucks. I have been using that for years. I started using that on my ducati exhaust tips and i later started using it on ANY aluminum,titanium. I even use it to polish control arms on my n55. im just a clean freak like that i like everything from top to bottom to shine. It is completely! safe and it literally does the job.

Heres how to use Blue Magic Polish:

1. Put on latex gloves
2. Get a finger tip amount and start rubbing the area you want to polish ie(tips, calipers, etc).
3. Using a paper towel or any soft cloth, wipe until the polish and dirt is gone.
4. Re apply as needed until all dirt/grease is gone
5. Enjoy the shine!

+1 for eagle one wadding polish. Just don't let your SO try it on her copper bottomed pots and pans, or you'll have to buy a new tin.

Edit: since I just ran my car through the car wash this morning (yeah, I know, it really needs a detail but I don't have the time... just cleaning up little bits and pieces as I can) this thread made me go out and polish my exhaust tips... much better!

Question: it appears that the rolled edge of my tips was painted black. (335i, non-S) was that factory? Doesn't really matter in the grand scheme of things, just curious. I originally thought that it was exhaust carbon so I started wiping it with acetone, it's still about half there. Not sure if I should strip it all off or touch it up, and that's more of a "which do I think will look better" kind of decision.
