my father in law is a high school science instructor and his school district is moving him into their new high school...this past week he found a couple of older and smaller carboys in his supply closet which were empty...he has offered them to me but i don't know what has previously been in them...
are there any steps outside of the normal cleaning/sanitizing with starsan that i need to do to be sure that they are clean no matter what was in them or should i just pass them up?
