Exhaust burned pants and now I can't scrape the polyester off the chrome

Got a new chopper with a Medustas exhaust, I rode in loose (100% polyester) pajama pants. Apparently the wind would push the pants onto the exhaust and the pants material burned onto the exhaust.
Trying to scrape it off with a plastic scraper but only the small stuff is coming off and the big pieces are caked on.
I'm afraid to use the metal/razor scraper because it might take off some of the chrome finish.
What's the best way to deal with this?
(PS I Know the left brown area looks like it's rust but it isn't)

Steel wool, like 000 will clean it off with no issues!

It was a quick test ride around the block after having changed some fluids

Ah... I can remember riding in shorts, T shirt and flip flops. Oh, to be young and free/stupid again...

I'd try the steel wool [stiff rag may work] with either a solvent or soap as a lubricant.

Mineral spirits should soften the polyester but I don't know if it's safe to use on chrome.

Mineral spirits shouldn't hurt chrome plating.

I'd be nervous to use steel wool on an expensive item like that. I'd try a solvent first.

("Test in an inconspicuous area...")

The steel wool (0) was not only dulling the chrome finish but also not removing the gunk. I stopped as soon as I started noticing this, shouldn't have used it in the first place
