Remove burnt plastic from chrome?

Aloha. Don’t worry, I didn’t chrome-plated my big one. That’s really ned I’ve got an LS 650 Savage standing here and there was a textile pants unbeautiful contact to the exhaust. Result: Nice holes in the pants and black pampe on the exhaust. The bigger chunks almost jumped away by themselves but there’s still a lot left that doesn’t want to go away. So how do I get that wech? Nevr dull I tested but does not bring anything. What solves the plastic without attacking the exhaust? Greetings Maro
