What is the most effective method to remove tea stains from cups

The most effective methods for removing tea stains from cups include baking soda, white vinegar, salt, lemon juice, toothpaste, etc. Baking soda is an alkaline substance that can neutralize acidic components in tea stains. Mix baking soda with water to make a paste, dip it in a soft cloth and wipe the cup wall. Stubborn tea stains can be left to stand for ten minutes before rinsing. This method is safe for ceramic and glass cups and will not damage the surface of the cup body.

2. White vinegar

Acetic acid in white vinegar can dissolve theophylline precipitate. Mix white vinegar and warm water in a 1:1 ratio to soak the tea cup. When the tea stains are thick, heat the solution to enhance the effect. Be careful not to use it on metal cups, as acetic acid may corrode the metal layer and cause discoloration.

3. Salt

Salt particles have physical friction. Take a small amount of salt and sprinkle it directly on the moist tea stains. Use your fingers or sponge to wipe in circles, which is suitable for removing newly formed shallow tea stains. After cleaning, the salt should be thoroughly washed to prevent residue from affecting the taste of the beverage.

4. Lemon Juice

Citric acid can decompose tea polyphenol oxides. Fresh lemon slices can be wiped directly onto the cup wall, or lemon juice can be mixed with hot water and soaked for half an hour. This method can also eliminate odors, but long-term use may cause the surface of plastic cups to become rough.

5. Toothpaste

Toothpaste contains friction agents and surfactants. Choose regular white toothpaste to apply to tea stains, and gently brush the gaps with a toothbrush for better results. Avoid using toothpaste containing particles to prevent scratching transparent glass cups.

It is recommended to rinse the tea cup immediately after each use to avoid the accumulation of tea stains. Stubborn tea stains can be softened with hot water before treatment, and for metal cups, baking soda or salt should be preferred for isothermal treatment. After cleaning, invert and dry to prevent water stains, and regularly boil and disinfect with boiling water. When mold stains appear on tea cups that have not been used for a long time, they need to be soaked in diluted bleach for sterilization before removing stains.
