How do you clean mold from a pizza stone or do I need to through it away?
If a pizza stone is allowed to get moldy it is probably best to
just give it a toss, because removing the mold would require using
harsh chemicals which would be absorbed into the porous stone.
So how is it even possible for a pizza stone to get moldy in the
first place? It sounds as though the pizza stone was washed with
water and put away wet or damp (in a dark place) and not used for a
lengthily time.
Mold is a fungi that can grow on just about anything, including
a pizza stone. Mold thrives in areas that are damp, humid and
sheltered from sunlight. The best way to prevent mold from forming
on a pizza stone is to keep the stone dry.
Personally, I never wash my pizza stone. I just wait until it
cools off and then brush anything that's baked on with a stiff
brush. I hope this helps.
