Try removing it, cleaning with solvent and lay the exposed surface on a slice of raw potato for 24 hours etc...
Many folks like to do this to their pocket knife (stab into a tater to blacken"... I think they claim it actually creates some sort of hardened surface in the oxidizing process...
My son made me cringe when he did this as told to a brand-dang-new Case XX pocket knife...
It is also supposed to resist rust longer as this surface material is actually chemically different than the steel it once was...
