grubby flywheel

[Yellow]

i managed to get a brand new lb flywheel today only thing is it was in the car abandoned in a mates garden with no bonnet or protection from the weather.once removed i gave it a quick clean off but has a black mark left from the clutch plate would this need refacing or can i wet and dry it back smooth.

I would of thought a little tickle with a bit of 800 wet'n'dry would do the trick
