Moldy L' Art du Son?

Hi, I've had nearly a full gallon on the afore-mentioned record cleaning agent stored for some time. I decided I would start using it, only to discover it had mold, or more likely, algae, growing in the bottom. Moving the container slightly caused the growth to become suspended in the solution for a time. Can this contaminent be filtered out, or does the whole thing have to be tossed?

Thanks,

Dan
