To speed up the cooling time, wear oven mitts to take the stone out of the oven. Set it on the stovetop to cool. If you don’t feel like cleaning the stone right away, leave it in your cold oven overnight and work on it the next day.
You can also try plastic scraper tools, but they may not be strong enough against burnt-on food.
Don’t soak the stone in water or it can take a really long time to dry. Rinse the stone with just enough running water to remove the burnt-on food.
Baking soda neutralizes odors so it can remove burnt smells from your stone. It’s also slightly corrosive, so it can clean the top layer of the stone.
You should also avoid cleaning the stone with harsh cleansers or bleach since you won’t be able to completely rinse them from the stone.
Since heating the stone can cause it to smoke, open a window for ventilation.
Cool the stone for at least 2 hours. If you want to clean it the next day, leave the stone in the oven overnight.
If there are still stains, you could try spreading a mix of 1 baking powder (12 g) with 1 teaspoon (4. 9 ml) of water over them and rinsing the stone.
