Wipe off all the black stuff, let it dry for a while and then lube.
If you want good solvent for chain cleaning (except maybe in California) go to the hardware store and buy
naphtha. It's very similar to clear mineral spirits, except it dries slightly faster.
BTW- use naphtha outdoors or with good ventilation, and keep the container tightly closed for storage.
