Wood pizza serving bats should never be used under heat lamps or soaked in water. If necessary they can be seasoned or sealed with oil. To seal, wipe any food safe oil (like mineral oil) on the surface of the peel. Some oils will eventually go rancid; these oils should be avoided. If sealed, the bat is less likely to pick up unwanted odours, food particles and moisture. This will not increase the life span of the bat. Bats eventually wear out. If bat warps, leave overnight with the warp facing up and it should flatten out. Avoid leaving on hot surfaces, which could increase chances of warping. Pizza serving bats are not dishwasher safe.
