How to clean tea stains on plastic cups?

In life, many people have the habit of drinking tea, which can quickly eliminate impurities in the body and is very beneficial to our health. Most people like to use plastic cups to drink tea, but everyone knows that if you drink tea in plastic cups for a long time, tea stains will appear on the edge of the cup, and tea stains are very difficult to clean. This makes many people very distressed. It’s a pity to throw the cup away, but if you don’t throw it away, the tea stains are really difficult to clean and affect the appearance of the cup. So how to clean tea stains in plastic cups?

1. First moisten the tea set with water, sprinkle some salt on it, and then wipe it with a soft cloth or directly with your hands to remove the tea stains.

2. Leftover cold drinking water, such as cola and carbonated water, can be used as detergent to clean containers with tea stains and scale. This is because the acidic substances in the cold drinking water will produce a double decomposition reaction when they meet with tea stains and scale. The harmful substances in the tea stains and scale will dissolve in the drinking water. Therefore, generally do not use cups with tea stains and scale to drink cold drinking water.

3. To remove small pieces of tea stains, soak them in a solution of bleach or cleaning powder and leave them overnight to remove the tea stains.

4. You can scrub it with toothpaste or crushed egg shells, then rinse it with clean water.

5. Put a small spoonful of orange powder or orange juice in a teacup or teapot, fill it with water and leave it for 2-3 hours. This will make the tea stain lose its adhesion to the tea set and make it easier to remove.

6. You can peel the potatoes, put all the peels into a teapot and a teacup filled with water and heat them to boil. After the water boils, let it cool down a little before scrubbing. This will easily clean the tea stains attached to the bottom of the teapot and teacup. The principle is that potatoes contain starch, which has strong adsorption capacity, so it is easy to remove the scale in the cup.
