Shelf life on chemicals?

Hello everyone!  Is there is a shelf life on the chemicals in the True Tan System from WASCO? I have some chemicals left from an old reptile tanning kit that was purchased about 14 years ago.  The tanning crystals have clumped together in a hard lump but I am sure they would dissolve.

14 years seams like an awful long time to me. I don't know what the answer is, but I wouldn't use it. I'd just get some new and toss that. I wouldn't take the chance of losing something.

Thanks Redwolf.  That's what I was thinking, but I hate to throw anything away that MIGHT be OK... LOL (Going to the trash tomorrow).
