This article provides tips on how to clean the bottom of a pot or pan effectively. The first step is to remove any excess food particles by scraping them off with a spatula. Next, sprinkle baking soda or salt on the burnt surface and add a small amount of water to form a paste. Let it sit for a few minutes before scrubbing the bottom with a sponge. For stubborn stains, vinegar can be used instead of water. Finally, rinse the pot or pan thoroughly to remove any residue.
