^ what he said. lol.
Might take longer for all the levels to drop cause there's probably a lot of leftover organics, even after you rinse it, but if it's been kept dry with no contamination it should be good to use.

I'm sure someone's gonna pipe up and suggest an acid bath for the rock, but I've never done it so won't say anything else on it.
