What to do if the bottom of the pot is burnt?

The second method is to boil orange peels in water to clean the bottom of the pot!
Orange peels have natural cleaning properties and can remove dirt and odors. Put the orange peels in a pot, add an appropriate amount of water, bring to a boil, then reduce to a simmer and cook for about 10 minutes.
After turning off the heat, let it cool for a while until the orange peels and water in the pot have cooled down before using it. Then pour the orange peel water into a bowl, and use a cloth dipped in the orange peel water to wipe the bottom of the pot. This will easily remove any burnt residue and restore the pot's shine.
A reminder: when using orange peels to clean the bottom of pots, be sure to wait for the water in the pot to cool down naturally before pouring it out. Otherwise, the high temperature will cause the orange peels to burn even more and will also affect the cleaning effect.
