Had this discussion with a friend the other night; how do you clean a pizza stone? Apparently it's easy to ruin one by washing it with soap. The stone I own, did not come with cleaning instructions, so I did some research [as mine is still on the counter top with day old crust and cheese stuck to it] and this is what I found unanimous and universal for cleaning it:
- Use a kitchen scraper to get rid of the stuck on pieces.
- Wipe with a damp [water only] sponge or cloth.
- Submerge in warm, clean water, again - no soap! Soak for 20 minutes to completely saturate the porous ceramic surface.
- Air dry overnight.
So know we all know.
