How to thoroughly clean tea stains from glass cups

Tea stains on glass cups can be thoroughly cleaned with baking soda, white vinegar, salt, lemon juice, or specialized cleaning agents. Tea stains are mainly formed by the oxidation and deposition of tea polyphenols, and long-term accumulation may affect appearance and hygiene. Baking soda is an alkaline substance that can react with acidic components in tea stains. Mix baking soda and water into a paste and apply it to the tea stain, let it sit, and then wipe it with a soft cloth. This method has a significant effect on stubborn tea stains and will not scratch the surface of the glass cup. Rinse thoroughly with clean water after use to avoid residue.

2. White Vinegar

The acetic acid in white vinegar can dissolve mineral deposits in tea stains. Mix white vinegar with water in proportion and soak the tea cup. After half an hour, wipe it with a sponge. For details such as the edge of the cup mouth, a cotton swab dipped in vinegar can be used to focus on the treatment. White vinegar also has a sterilizing effect and is suitable for cleaning tea cups that have been used for a long time.

3. Salt

The particles of salt have a physical frictional effect. Sprinkle salt directly on the damp tea stain and rub it repeatedly with your fingers or a soft cloth. This method is suitable for handling newly formed shallow tea stains, and attention should be paid to controlling the force during operation to avoid scratching the glass. After cleaning, it is recommended to rinse with hot water to remove salt residue.

4. Lemon Juice

Lemon juice contains citric acid and vitamin C, which have a natural stain removing effect. Apply fresh lemon juice to the tea stain, let it sit in the sun, and rinse off. The fragrance of lemon can also remove the odor of tea cups, making it suitable for people who are sensitive to chemical cleaning agents. When dealing with thicker tea stains, hot water soaking can be used to enhance the effect.

5. Special Cleaning Agent

Commercial glassware cleaning agents contain surfactants and chelating agents. Soak the tea cup after diluting according to the instructions, which can quickly decompose organic stains. Choosing products with phosphate free formulas is more environmentally friendly and requires multiple rinses after use. This type of cleaner is suitable for cleaning tea cups with a large amount of dirt, but it is recommended for sensitive skin to wear gloves during operation.

After drinking tea from a glass cup in daily life, it should be rinsed with clean water in a timely manner to avoid the deposition of tea stains. Perform a deep cleaning once a week, and different cleaning methods can be used alternately. When cleaning, the water temperature should not be too high to prevent the glass from bursting. Stubborn stains can be softened with hot water first. When drying, place it upside down to prevent water stains from remaining, and store it in a ventilated place to keep it dry. Long term maintenance of cleaning habits can extend the service life of glass cups and ensure drinking hygiene.
