Was warming up the bike to let the battery charge up a bit. I had been lovingly polishing my baby with a microfiber cloth to remove stray fingerprints etc.

Sat the cloth on the seat and it vibrated off and fell against the exhaust just in front of the passenger footboard. Partially melted and now it has this ugly black pattern on the chrome.

Any good ideas on what to use to remove it?

 

Dude... I had that happen... it was NOT pretty getting it off. I scratched the heck out of the chrome... And then I had to take the heat shield off and buff it out with a polishing compound.

Took about 5-6 hours to clean up a 2 second mistake.

Good luck.

 

I don't have an answer to your question but I do question your judgement in letting it set there "warming up" long enough to get the exhaust that hot. The V-twin, air cooled engine is designed for cooling air to flow over the cylinder heads and unless you have a huge fan blowing air you're probably not doing the engine much good letting it set still and idle like that.

 

Warm the bike up to operating temp and then wipe the spot with a towel, it should come right off.

 

try some oven cleaner..
and put a battery tender on your bike...that is the way to charge and maintain your battery...as was said in previous comments what you did is a no,no....probably you created a bunch of condensation in the mufflers and the internals...bad.

 

I have had success with boot burns by taking very fine steel wool, liek the finest you can fine i think its 0000 and some goof off, or goo gone. make sure the pipes are cool. Apply the goof off to the burn and the steel wool, make sure it is nice and wet, then very gently, and i mean so gently your jsut kinda slowly dragging the steel wool over the burn, begin to rub, but at no time should you apply any pressure whatsoever!!! NO PRESSURE!!!! basicly the steel wool snags on the burned stuff and pulls it off. If your very careful you will get teh junk off with no scratches at all. BUT BE CAREFUL!!! then rinse and wipe with lots of water. make sure all teh stuff is off and finish up with some soap and water then water again.

This works liek a charm on boot burns, My ex girlfriend seemed to enjoy resting her boot on my pipes, lol.

Be patient, go slow and take your time and most of all
BE GENTLE
gentle.....

 

I had boot marks on my muff's... I used a little propane torch to heat up the mess,,,, it whiped off after a while

 

I've always had good luck with WD-40, Semichrome, and even carb/Choke cleaner. Warm the pipes up (not HOT though) and get as much off as you can with a cotton t-shirtm then wipe down with one of the three items listed above. Might take a little elbow grease, but it will come off. Also, someone listed Oven Cleaner above...just make sure you apply it to the rag and don't spray it on the bike. If you get oven cleaner overspay anywhere on a painted surface, kiss your paint goodbye.

 

I had a friend who was a detailer. He went around to different car lots back in college and detailed autos and motorcycles. He had some stuff that would take anything off. Boot burns, 5 seconds maybe. I would go online to a detail supplier. Call and talk to someone ,they can give you some ideas on good products that will keep the boot marks and other mishaps from being a problem. Hope this helps.
