Black gunk on tips

[RF Overlord]

Our new Silver Birch has this hard black coating on the underside of the tips and on the lower part of the rolled edge. This stuff looks like residue from exhaust condensation that got baked on. I've tried the following to remove it: Brakleen, gasoline, brake fluid, lacquer thinner, paint thinner, isopropyl alcohol, acetone, and Goo-Gone. The only thing that has any effect at all is Bon-Ami on a wet sponge, but even that is taking forever.

Any other suggestions?

[Bradley G]

thanks for the "tips" , LOL
I wish I had something to offer!

[RCSignals]

have you tried a mixture of vinegar and water? ;)

[RCSignals]

if that doesn't work try an orange cleaner or full strength Simple Green

Mary and Bob - Congrats on new ride.:D

Try metal polish such as semi-chrome.

some stainless polish with four OOOO steel wool won't scratch tips

Are you sure it isn't undercoating spray?

No - "This stuff looks like residue from exhaust condensation that got baked on."


Are you sure it isn't undercoating spray?No undercoating on the car.

Try Throttle body or carb spray and let it sit just a little. It is made to dissolve carbon, whitch sounds like what this is.

How about gas??

Find a fellow member that has replaced his original stock tips with beffle-free tips and take him out to dinner.

"FLITZ"......You can buy it at boating supply stores....It is a blue paste that comes in a tube.....cleans and polishes ANYTHING!!!:bows::beer:

If it's baked-on carbon, try using ammonia. Nothing loosens or removes carbon better than good old household NH4! Let it soak for 5 minutes first.

Best luck,

I have this problem with my 04 DTR. It builds up during the winter months. I use Simple Green on a 0000 steel wool followed by a metal polish. Flitz works well.

I use Simple Green on a 0000 steel wool followed by a metal polish.We have a winner! It still took a huge amount of elbow grease, but it finally all came off. Many thanks to all who replied.

In the future, a simple Brillo pad (or SOS) with lots of water will shine the hell out of stainless pipes. Found this trick out a long time ago when I was into 5.0 Mustangs. Will not scratch the pipes as long as you keep the pad wet. They come up as good as new with very little effort.

Ditto!

This is one of my tricks in the bag for stainless & chrome. Really does work.

[MENINBLK]

You could have just used Eagle One Nevr Dull.
It takes all the black stuff off my tips very easily.

OOOO steel wheel has pratically no chance of scratching polished exhaust tip making it almost foolproof.

:D

I didn't notice you ALREADY tried gas :( glad you got it off though :D

[wchain]

Meg's official recommendation is Wenol, but I'm glad to hear you got the stuff off! I could have supplied you with some Bubb Rubb Tips....

RF,
You will have to use Gasoline only and quit using Diesel Fuel. It is either save the Dollar or Elbow Grease.

Even though you already got it off....When I used to detail cars, we used isopropyl alcohol and steel wool.....very easy to work and shines them up like new.
