When drinking tea with a thermos cup, it often produces some scale or tea stains. How can these dirty things be cleaned quickly? Here are four simple ways:
1. The leftover cold drinking water, such as coke and gas water, can be used as detergent to clean the containers with tea scale and scale. This is because the acid substances in the cold drinking water will have a double decomposition reaction when they meet with tea scale and scale, and the harmful substances in tea scale and scale will dissolve in the drinking water. Therefore, generally, do not drink cold drinking water with cups with tea scale and scale.
2. Prepare hot water, then take a potato and put it into the cup. Pour the prepared heat into the cup and soak it for about 10 minutes, and then you can easily wash the tea scale off the cup. Its principle is that there is starch in the potato, which has a strong breathing force, so you can easily remove the scale from the cup.
3. In addition to a small piece of tea scale, it can be soaked in the solution of bleach or cleaning powder and placed for one night to remove the tea scale.
4. As long as you crush the eggshell, put it into the dirty cup to be cleaned, then drop a few drops of vinegar, shake it slowly, and then clean it with a brush, you can clean the parts that are not easy to clean at ordinary times.
