getting the black gunk out of chrome exhaust tips

emr0591 · 02-10-2010, 06:32 PM

How do you do this? The outside of the tips are shiny, but the insides are full of black gunk.

Why would you clean the inside? The exhaust gases are just going to blacken the surface again within a few miles anyway.

You're missing the point. A $1000 detail could be ruined (or severely impacted) by a single puddle.

For the insides, I'd probably start with some sort of APC (such as TAW or CG Grime Reaper) with a brush or blue Scotch sponge to agitate, then follow up with some wadding polish (Eagle One) and/or something like OPT Metal Polish.

+1

If you maintain them it's not a problem.
When you let em get out of hand, you might have to break out some #0000 steel wool!

thanx for the tips, guys. Just one question: what is an APC?

It stands for All Purpose Cleaner. There's a wide variety of products that could be described as APCs - from Megs D101 for interior use to CG Grime Reaper which is more powerful and could be used for engine bays, tires, or the inside of exhaust pipes.

Ive been cleaning the inside of mine since day 1. Really sets you apart from others at car shows/meets ETC

Normally, soap and water does the trick if you maintain.

Same goes for cleaning the inside of the wheels and behind the spokes.

Anyway, if it gets a little tough I usually use some basic OTC metal polish for the inside.

Dont waste the good stuff on the inside of the tips

The dark "holes" offset the shine on the chrome.

That's my story and I'm sticking to it!
