If you forget about a cup of tea or coffee for a long time, a film will definitely appear on it, which can be difficult to wash off with ordinary detergent.
In this case, it is necessary to pay attention to folk methods of getting rid of plaque.
For example, baking soda, which is always in the kitchen of any responsible housewife, copes with the problem perfectly.
The product must be diluted with water to a paste state and then applied to contaminated areas.
After 5-10 minutes, you can start cleaning with a soft, damp sponge.
In addition, citric acid will help.
You need to take just one teaspoon of the product and dilute it in a cup of hot water. The solution should be left until it cools completely, and then all that remains is to rinse the dishes.
Another ideal remedy is toothpaste. Not everyone knows, but it gently cleans dishes even from old stains.
