Convenient, environmentally friendly and hydrating, thermos bottles are basically equipped by modern people, but incorrect cleaning and use of thermos bottles may also be harmful to health.
The thermos bottle comes into contact with the mouth, and the amount of microorganisms and bacteria is considerable. Because after brushing the teeth, there are still 200 million bacteria in the mouth. It is recommended to clean the thermos bottle well every day.
What other uses of thermos can cause us to accidentally drink a lot of bacteria and microorganisms?
1. Thermos bottled latte, fruit water, so convenient?
High-protein beverages such as milk and soy milk tend to breed bacteria and deteriorate under the condition of heat preservation, and will also adhere to the inner wall, making cleaning difficult; in addition, acidic substances such as carbonated drinks and juices will dissolve the nickel-chromium metal on the inner wall. It is recommended to pack in a thermos bottle Boiled water is good, and occasionally black coffee (without sugar or milk) can also be used.
If you don’t like drinking boiled water, and want to add a slice of lemon or apple to the water to increase the taste, it is recommended that the structure of the cup is complete (no scratches or damage to the inner membrane), but it is not recommended if there are scratches. As for whether the thermos can hold tea? It is recommended to use materials above 304 as much as possible, and it is safer to form one piece. If there is a white iron smell, it is recommended not to refill drinks.
And do not install hot water to avoid burns. Jiang Zhigang suggested that it is best to pack cold water first and then hot water. The water temperature of 42°C is palatable and safe to drink.
2. Will the thermos dissolve the plasticizer?
The use of plastic for the lid of the thermos bottle is to enhance the airtight function and facilitate portability. The No. 5 plastic (PP) is selected for high temperature resistance, collision and stability. Compared with other plastics, it is safer, and there is no need to worry too much about the dissolution of plasticizers.
Also, don’t fill up the thermos bottle until it’s full! It is good to be 70% full. Water contacting the bottle cap will easily cause plastic aging or bacterial contamination, so it is best to avoid it.
3. Can all stainless steel be used as thermos?
wrong. Stainless steel has different hardness. It is divided into several categories from industrial use to precision medical materials such as scalpels. Usually, 304 stainless steel (chromium-nickel ratio marking method is 18-8) is the most suitable for drinking water thermos, which has sufficient hardness and acid and alkali resistance. , High stability and reasonable price. It is recommended to look at the SUS mark on the cap or bottle body (Steel Special Use Stainless, stainless steel standard).
4. Can the thermos be cleaned with clean water?
Clean water cannot wash away the dirt in the grooves in the thermos. It is recommended to use cotton swabs or sharp-angled brushes to deal with crevice dirt, such as the lid of the cup and the cup body that touches the mouth, to be specially cleaned, and it is best to clean it every day so as not to accumulate dirt.
Sometimes the dirt adhering to the inner wall contains grease and is not easy to clean. You can use some detergent or baking soda to clean it with a soft brush, and then rinse it with water. Never use a steel brush or a vegetable melon cloth to scratch the inner membrane.
5. Thermos bottle with inner coating is better?
Open the thermos, the stainless steel integrally formed on the inner wall is better than the coating.
Stainless steel is usually mirror-finished, and the inside of the coating is mostly gray. For example, improper brushing, ice cubes or external force collision will easily cause the coating to peel off, so be careful when using it.
In addition, the thermos bottle is mainly made of smooth and plain colors. The colors are too bright, such as positive yellow and red paint, and the lead content is high. If the mottle falls off, it is easy to accidentally eat lead poisoning. Pay special attention when choosing a thermos for children.
6. Stainless steel thermos never need to be replaced?
wrong. If the collision is too severe, the inner membrane is scratched or damaged, and it is easy to hide dirt and dirt, and it is recommended to replace it.
In addition, please check whether the silicone or plastic of the bottle cap is cracked or brittle, and environmental hormones may be dissolved. It is recommended to purchase replacement parts from the original factory for safety.
