    Well, we've just had the melted sole on the exhaust, how about an errant plastic bag, or perhaps styrofoam, that unknowingly flew onto the cyclnder fins and melted.:cry

    What to clean this off with? It's now quite a few miles old but it would be nice to get it off.

    Thanks.:D

    First thing I'd try is acetone or nail polish remover with a toothbrush. That stuff melts a lot of foams and plastic in their normal states so I imagine it might help you remove the melted version.

    Be careful if your fins are painted, it might want to take the paint with it...

    I had a plastic grocery bag land on the hot exhaust cross pipe of my Roadster. I was in heavy rush hour traffic on I-80 and was not able to get over to the shoulder to stop and pull it off, so it melted. I mean it really melted.

    I used a solvent called Xylene and a green scrubby thing, which got a lot of it off, but it took effort. After a while, the rest of it burned off.
