Sihaiwang: everyone is familiar with and often uses the heat preservation cup. If the heat preservation cup is used for a long time, there will be scale, tea scale and other situations, which is difficult to clean. So, how should we clean the thermos cup?
The cleaning method of tea dirt, the key of tea dirt is baking soda. Sodium bicarbonate is weak alkaline. The reason why it can remove the tea dirt is mainly the swelling effect, so that the adhesion of the tea dirt can be reduced, and it is easy to lift it off the cup wall.
Tea dirt has been removed, so what's the best way to remove it?
You can put lemon slices and lemon juice in the thermos cup, add boiling hot water, soak for about an hour, and then sponge and wash it. No lemon with white vinegar also has the same effect, but because the taste of vinegar is stronger, after cleaning with vinegar, and then wash off the taste with hot water.
In addition, due to the special structure of the insulating cup, some important parts need special attention when cleaning. The internal structure of the heat preservation cup is relatively complex, especially the groove patterns at the bottle mouth and cup cover are many, so it is easy to hide dirt and scale without careful cleaning. Clean water can't clean the dirt in the groove of the insulation Cup. It's recommended to use cotton stick or brush to clean the dirt in the gap carefully. Special attention should be paid to the cup cover and the cup mouth contacting the mouth, and it is better to clean it every day after use, so as not to accumulate dirt and bacteria. Sometimes, the dirt on the inner wall contains grease, which is not easy to clean. You can use a soft brush with detergent or baking soda to clean it, and then rinse it with water. Never use stainless steel ball or cleaning cloth to avoid scratching the inner membrane.
