When you frequently drink coffee, tea or drinks, the inner container will change color. This is normal. Do not use steel wool to rub it. We recommend a few practical methods for cleaning. 1. Salt Dip some salt into the cup with your fingers (it is better to wear gloves). Wipe the coffee stains on the inner wall back and forth until the coffee stains are removed, then rinse with clean water. 2. Toothpaste: Take an appropriate amount of toothpaste on your fingertips, rub the inner wall of the thermos cup with your fingertips, and rinse after about a minute. One advantage of toothpaste cleaning is that it is less likely to leave any residue and makes it cleaner. 3. Add a few drops of dishwashing liquid into the thermos cup, then use a clean sponge dishcloth to gently wipe it back and forth, let it sit for a few minutes, and then rinse with clean water. 4. Baking soda: Put a fingernail-sized amount of baking soda into a thermos cup filled with hot water, shake gently for a moment, and then soak for about an hour. After an hour, you will see a clean thermos cup. After brewing coffee in a deodorized thermos, there will be a strong coffee smell. If the coffee stains are removed, it will not go away for a while. You can take these measures: 1. There are many pores on the surface of scented tea leaves, which have strong adsorption properties. Just like activated carbon, it can absorb environmental moisture and odors. Take an appropriate amount of scented tea and put it into a thermos cup to brew. 2. Orange peel Orange peel has aromatic substances that can remove odor. Wipe the thermos cup with freshly peeled orange peels, or soak two pieces of orange peel in the thermos cup. Pour it out after half an hour, and the thermos cup will exude a natural fruity aroma. 3. Vinegar If the coffee in the thermos cup has a strong smell, you can pour a few drops of vinegar into the thermos cup, shake it gently and then rinse it with water. This can not only remove the smell, but also sterilize the thermos cup.
