How to remove tea stains from the bottom of a teapot

The tea stains at the bottom of the teapot can be removed by soaking in white vinegar, wiping with baking soda, dissolving in citric acid, and other methods. Tea stains are mainly formed by the deposition of tea polyphenols and minerals, and long-term accumulation may affect the appearance and hygiene of tea utensils.

1. Soaking in white vinegar

The acetic acid in white vinegar can react with the calcium and magnesium ions in tea stains, softening stubborn deposits. Mix white vinegar and water in a 1:1 ratio and pour into a teapot. Soak for 2 hours and then scrub with a soft cloth. This method is suitable for ceramic and glass teapots, which may cause corrosion to metal teapots and should be used with caution.

2. Baking soda wiping

The micro particles of baking soda have a physical friction effect, and its weak alkalinity can decompose the organic components in tea stains. Take a small amount of baking soda and add water to make a paste. Dip it in a sponge and repeatedly wipe the tea stain area. This method is safe and non corrosive, especially suitable for tea sets with glazed protection on the inner wall.

3. Citric acid dissolution

Citric acid has a strong dissolving effect on tea polyphenol oxides. Dissolve 5 grams of food grade citric acid in 60 ℃ warm water, pour it into a teapot and let it stand for 30 minutes. The tea stains will naturally fall off. This method has a significant effect on stainless steel teapots, but plastic teapots may deform due to high temperatures.

4. Salt Friction

Coarse salt particles can form mild mechanical friction, which, when combined with lemon slices, can enhance the stain removal effect. Mix salt and lemon juice into a grinding paste, and use a soft bristled brush to clean in circles along the texture of the tea stain. This method is suitable for handling tea utensils such as purple clay pots that are not suitable for chemical cleaning.

5. professional cleaner

Tea set specific cleaner containing sodium bicarbonate can oxidize and decompose deep tea stains. Dilute according to the instructions and soak in the teapot. Pay attention to thoroughly rinsing to avoid residue. This type of cleaning agent has a significant effect on severe tea stains, but it is recommended for sensitive individuals to wear gloves during operation.

Rinse the teapot with clean water in a timely manner after daily use, and clean it regularly every week using the above methods to prevent tea stains from accumulating. Avoid scratching with hard objects such as steel wire balls to prevent damage to the surface of the tea set. Special materials such as purple clay pots are recommended to be maintained only with clean water and soft cloth to preserve their breathability. After cleaning tea stains, they should be washed and disinfected with boiling water, dried, and then stored in a well ventilated place.
