I have this black pake crankset:

And I was wondering A. would it be safe (aka not seriously damaging to the integrity of the material) to take the paint off the chainring, and B. what would I use to strip it? I can't tell what the black surface is, I know their cranks that AREN'T black or silver are anodized, but I don't know what kind of surface these have. Would paint stripper work? Or the oven cleaner method?

Any ideas?

Thanks
