Cleaning Black ceramic pipes

[Skin]

Whats needed to clean "boot" or burnt pants off the black ceramic pipes without ruining the finish? Vance and Hines says only to use mild soap and water. That won't get burnt stuff off pipes.
Thanks Skin

Try WD - 40  It might work. Good luck.

Phil, Hey Bro, we're doing just fine now that Pearl got a job. She was 7 months without. She starts this coming monday. You guys ok?

I'll give the paste wax a try, as will the other options. It's a customers bike so I'm going to try and find someway to try it off the bike just in case these ideas don't work. I'm not into buying a new exhaust for this guy.

Thanks for the other advice
