Are you talking about the underside of the stock cannisters that are painted flat black?

my idea is to use a abrasive cleaner if it is not on paint, on paint im not sure what to tell you. for grime that is not on plastic or paint i use carb and choke cleaner. i know it sounds crazy but this stuff cleans carbon build up off metal and thats no easy task. so grime on a pipe is no task. greese and oil are a simple task as well. get a cloth and a can of it and go at it. NOT ON HOT EXHAUST!!

I've used TurtleWax bug and tar remover with lots of success on the heat shields and exhaust tips for removing exhaust staining.

+1 on the bug and tar remover. I use acetone on really badly stained non-painted surfaces.

Mothers metal polish does wonders on basic tarnished metal surfaces.

For something more involved (like slightly rusted headers) try wet sanding with 400 or 600 grit sandpaper (depending on the severity). Followed by Mothers.

After that - Bling all the way home!

It's a fool who looks for logic in the chambers of the human heart.

I've tried various road film and bug removers and they seem to all be good. I like Turtlewax and "Formula1" as they seem to do the job here.. Sometimes, fo more stubborn tar stains, I use white spirits, turps or kero... For Stainless steel pipe cleaning of discoloured areas, I use very fine steel wool or pot scouring pads - works a teat...

I've found the headers on the Hornet (as we call it in New Zealand) dirty up at the top pretty quickly - Autosol (chrome/metal polish) works well - BUT it works even better on removing this crap if the header is just warm - I run the bike for 10 seconds or so then polish.

I've polished the stainless heat shields on the mufflers. Every now and then I give the black painted parts of the pipes are good wipe down with a rag sprayed in WD40.

Works a treat and I'm a fussy bugger.

It has been mentioned several times in this fourm that a 3M green scrubbie works better than any polish or remover. Just get a bucket of water and scrub each pipe until its bright silver. (Took me about an hour for all four.) Once they get hot they turn a nice gold color again. (I kind of wish they would stay silver.)

I got no time for the jibba-jabba. - Mr. T
