Q. Please tell me how to remove the scorching left in the bottom after use.

If it gets scorched, boil water in the pot, turn the heat down to low, add about 1 tablespoon of baking soda, and simmer for 2-3 minutes. After it has cooled naturally, rub it off with a melamine sponge.

Please refrain from using a melamine sponge on the heating element on the back, use a soft sponge instead.
