Black specs (road grime) under exhaust...
« on: September 04, 2016, 12:59:40 AM »

Sometimes I like to take the bags off to get to the exhaust and rear wheel.  So while cleaning the chrome exhaust, I noticed some black speckles when you look up close at it.  It appears to just be typical road grime.  I can scrape them off with my fingernail but that's a pain.  Anyone have a better cleaner or solution that works?  I tried simichrome, s100 detail wax and bug slide with negative results.  Simichrome helped a bit but didn't make the exhaust feel smooth to the touch.

Maybe try spraying it down good and letting it soak with something like Adams polishes all purpose cleaner then scrub with a soft damp rag or wash mitt?

If it's worse on the left muffler than the right, I'd suspect it's the stuff that sheds from a new belt.  New belts have a coating on them to help with initial break-in, and it wears off quickly.  I cleaned mine when I did my first service, with mineral spirits on a rag and a little elbow grease, followed by a good wash and then wax.

I would expect it to also be on the wheel.

It does appear to be more on the left than right.  I like the idea of 0000 steel wool and the Goof off, which I have.  What can actually scratch the chrome if not careful?

Steel wool, even 0000, can scratch.  Stick with a solvent on a rag and some elbow grease, or one of those plastic scrub pads.  Let the solvent soak the deposits for a short time, then wipe/rub.

Thanks Jerry, I kinda thought it could scratch.  Solvent good.

Jerry I have used 0000 steel wool wet for years and not one scratch. No need to get aggressive the black stuff comes right off.

Had good success with Goof Off Pro Strength remover on chrome. Takes tar and boot rubber right off.  Does not appear to harm the chrome but would not get it on aluminum or painted surfaces.  Probably would not hurt to wash area afterward and polish to remove any remaining solvent.

I'll do you one better than steel wool ... SOS pads.   The soap does most of the work.  No scratches (look at my bike).  Easy, peasy.

Sorry, but you did put micro scratches in it. Goof off, tar remover, a little mineral spirits on a rag, but NEVER use anything abrasive. Whether it is steel wool, brass wool, scuff pad or whatever they all do scratch. If you do it continually in the same area that pretty chrome will become pretty shiny copper because you are taking the top layer off with the scratchy stuff.
