How to remove black stains when cooking rice in a clay pot is burnt

The black stains caused by cooking in a clay pot can be removed by methods such as baking soda, white vinegar, tea leaves, lemon juice, or salt. These materials can effectively decompose burnt materials without damaging the clay pot material. Baking soda is an alkaline substance that can react chemically with burnt substances. Mix baking soda and water into a paste and apply it to the black stain, let it sit for a period of time, and then wipe it with a soft cloth. This method is suitable for handling newly formed mild burnt paste and has no corrosiveness to the glaze surface of clay pots. If the black stain is stubborn, repeat the operation to avoid scratching with hard objects such as steel wire balls.

2. White Vinegar

The acetic acid in white vinegar can soften carbonized substances. Mix white vinegar and water in proportion and boil, then turn off the heat and soak the clay pot. After the water temperature drops, clean it with a sponge. This method has a significant effect on black stains that have been deposited for a long time, but attention should be paid to vinegar residue. After use, it is recommended to rinse with clean water multiple times to avoid prolonged contact of acidic substances with the clay pot body.

3. Tea

Tannic acid in tea has a cleansing effect. Wipe the black stains with soaked tea leaves or strong tea soup, as tea polyphenols can decompose organic matter. This method is suitable for treating shallow stains and is environmentally friendly and safe, especially suitable for colored glazed clay pots. After wiping, it is necessary to rinse with clean water in a timely manner to prevent the brown color from seeping into the fine pores of the clay pot.

4. Lemon Juice

Citric acid can dissolve protein like burnt substances. Boil lemon slices in water and soak them in a clay pot, or squeeze the juice and apply it directly to the black stains. Natural fruit acids can remove odors without leaving chemical residues, making them suitable for treating dirt caused by food burning. Wear gloves to protect your hands during operation, and use cooking oil to maintain the surface of the clay pot after processing.

5. Salt

Salt particles have physical friction. Mix salt with a small amount of water to make a grinding paste, dip it in a soft cloth and wipe it in circles. Coarse salt is more suitable for removing thick layers of coke, but the force should be controlled to avoid scratching the pot body. Rinse with warm water after completion, and long-term use can maintain the smoothness of the clay pot.

It is recommended to control the heat and avoid dry burning when using a clay pot in daily life. Before using a new clay pot for the first time, rice soup can be used to boil and maintain it. Thoroughly dry after cleaning to prevent mold growth, and avoid stacking and rubbing during storage. If black stains are difficult to remove or cracks appear in the clay pot, replacement should be considered to ensure cooking safety. Regular cleaning using the above methods can extend the service life of the clay pot while maintaining the original flavor of the food without contamination.
