Cleaning a cooking pot that has boiled dry is often an arduous project. It is tempting to throw away the pot because of the unsightly stain or amount of burnt-on residue. The bottom of the pot may turn dark or white from the mineral deposits from the water or liquid. If stew, chili or another type of food boiled dry, this leaves a thick, stuck-on residue that requires patience and persistence to clean. Don't discard the pot into the garbage until you attempt to clean it with the right products.
Remove the cooking pot from the hot eye on the stove. Allow it to cool off before attempting to clean it.
Discard any remaining food from the pot into the garbage or your disposal. It is likely to have a burnt taste.
Add water to the pot and allow it to soak for at least 30 minutes. Try to remove any remaining food with a plastic scraper or plastic spatula. Pour the water and food debris down the garbage disposal once you loosen the food.
Fill the pot with 2 inches of warm water and drop in two to six fizzing tablets in it if the food residue or stain is still apparent. Denture cleaning tablets and the over-the-counter medicines that fizz and treat indigestion, heartburn and pain work well. The number of tablets depends on the size of the pot and thickness of the burnt-on residue. Allow the tablets to fizz for about 10 minutes. Scrub the pot with warm soapy water and a nylon scrubber. Rinse it well before drying with a clean dish towel.
Wet the pot if it only has mineral deposits or a stain from boiling dry. Sprinkle regular table salt on the inside bottom of the pot. Allow the salt to sit for about 10 to 15 minutes. Scrub the pot with a nylon scrubber until it comes clean. This works well for burnt milk and other stains. The salt is nonabrasive and does not scratch the cooking pot or cause any other damage.
Clean copper by sprinkling regular table salt over the inside bottom of the pot. Saturate a cleaning cloth with white distilled vinegar. Scrub the salt into the copper pot with the cloth. Rinse out the salt and wash in your normal fashion.
Boil 1 cup white distilled vinegar and enough water to cover the bottom of a stainless steel pot. Allow it to boil for about five minutes and then let the mixture cool. Scrub the pot with a nylon scrubber to remove stains and burnt-on food residue.
Add 2 tablespoons baking soda, 1 cup warm water and 1/2 cup of white distilled vinegar to the pot if it has a nonstick coating. Boil the mixture for about 10 minutes. Allow the pot to cool and then clean in your normal manner.
Moisten a cleaning cloth with white distilled vinegar. Rub the damp cloth over mineral deposits to remove them from a nonstick pot.
