You could always put rejex on them...makes cleaning VERY easy! Rinse them when you wash the car and wipe!

 

Try "Flitz" , jewelers rouge, or toothpaste

 

never had any trouble cleaning those stainless tips on any car. Just wipe with a little light rubbing compound. It comes off easy. When I put on my sharkwerk bypass I took the tips off and sanded and painted the ugly rusty y base and now the exhaust tips look really good and no rusty pipe shows thru

 

Before you do anything as aggressive as steel wool, try WD40.
Cheap and easy.
It might (likely will) require a few applications.
Spray on cold tips. Let sit for 30 sec or so. Wipe off with a soft cloth.
Worked well for me. But it sounds like yours are pretty messy.
Good luck.

 

Hey guys ... Just finished applying nevrdull and results are great! I can actually see the metal now!

What I did was take a soft clean cloth and wipe off whatever I could first, prior to using any chemical. Then I applied nevrdull all over the tips (that sounds dirty lol). I used a considerable amount of pressure and used several pieces of the nevrdull per tip. After doing that, I took another clean soft cloth and buffed it down/dried it off.

Looks so much better! Thanks for all the input!

 

You could consider doing something like this.. These would look great on your black P-car.

I had mine black chrome coated ~ it makes regular cleaning a lot easier.

 

+1 for rejex & also Star Brite Marine

When I wash the car I'll run a rag on the inside of the tips to clean them. Since I've been doing that for the last five years it's kept the soot from building up on the outside. I know I'm a little OCD.

 

This looks especially nice in tandem with the black 911 badge ...

 

Bug & Tar remover or WD40 first.
Then a little mag wheel polish.
Then they are easy to keep clean.

0000 Steel wool or scotchbrite pad + Barkeeper's Friend when they real bad.

 

Try Sonex wheel cleaner. Take a look at their website and look at some of the baked on wheel grime, rust, and baked on brake dust. Takes it right back to shinny clean. For 20 bucks it is worth a try.

 

All the cleaning methods are great, but they require me to actually 'clean' the tips regularly. There is no way in heck I'd clean my tips once a week or month. It may be a once a year thing. If I feel energetic once every 6mos.

That said, is it pretty easy and repeatable to remove the tips for cleaning from the pipes, or would the repeated removal and re installation eventually destroy the mechanism that attaches the tips (set screw, clamp, etc .. I don't know what it actually is)

 

I tried cleaning the inside of the tips. Outside cleaned up a little with Neverdull. But the inside is still covered with black soot. Steel wool didn't do anything (maybe I didn't scrub long enough). Neverdull didn't do anything for the inside. Sonax wheel cleaner, nothing as well.

Any other ideas?

Has anyone tried Barkeeper's Friend? That stuff is amazing on stainless steel cookware.

 

Take a look at the video....I think this would be a no brainer on the exhaust tips and very little labor involved.

Yeah, Sonax was amazing on my rims. Unfortunately, it didn't do squat for the black soot inside the exhaust tips.
