TO are typically not exposed to ait that long, and being as such, won't have that much die off. One can scrub them clean, and have no problems then, if so disired.
I've never had a problem with them. Just look the rock over and make sure theres no white fuzzy "mold" like stuff on it, nor any bad smells.
