How to clean a thermos cup for the first time?

1. After buying a thermos, first look at the instruction manual. Generally, there are instructions on it, but many people do not read it, so many people cannot use it correctly and the insulation effect is not good. Open the lid of the thermos cup, there is also a plastic water bottle like lid inside, which is mainly for sealing and the key to insulation. First add some cold water to rinse, then press the button to let the water flow out of the bottle stopper. This can clear out some dust inside.

2. Some thermos cups may contain polishing powder, so after the first cleaning, it is necessary to add an appropriate amount of neutral detergent to warm water for cleaning. After washing, rinse with clean water.

3. As you can see, there is a rubber ring inside the cup cap, similar to a bottle stopper, which can be removed. If there is a smell, you can soak it separately in warm water for a period of time. (Remember: Do not cook in a pot); There is a water sealed silicone ring inside, it is recommended to remove it and clean it properly, as there is usually thick dust on it.

4. Do not use hard objects to wipe the surface of the thermos cup, as it may damage the silk screen or transfer printing on the surface. Cleaning that cannot be soaked. When using, first add a small amount of boiling water and then pour it out before adding boiling water for better insulation effect. Adding ice water can still maintain the original cooling effect within 12 hours. Plastic parts and silicone rings cannot be boiled with hot water.

5. The above are just some necessary operations before use. A thermos can keep warm or be used to keep cold. If you want to keep it cold, you can add some ice cubes, which will have a better effect.

What to pay attention to when cleaning a thermos cup

1. The cleaning of stainless steel insulated cups requires attention to detail, and detergent, salt, etc. should not be used for cleaning. Because the inner lining of the thermos cup is sandblasted and electrolyzed, the electrolyzed inner lining can prevent physical reactions between water and stainless steel materials. Both salt and detergent may cause damage to it.

2. Do not use hard objects to wipe off the surface, as it may damage the silk screen or transfer printing. Cleaning that cannot be soaked. When using, first add a small amount of boiling water and then pour it out before adding boiling water for better insulation effect.

Precautions for using insulated cups

1. Preheat or pre cool with a small amount of boiling water (or ice water) for 1 minute before use to achieve better insulation and cooling effects.  

2. After filling the bottle with hot or cold water, make sure to close the bottle tightly to prevent water leakage and burns.  

3. Excessive use of hot or cold water may cause water leakage. Please refer to the water volume location diagram in the instruction manual.  

4. Do not place it near a fire source to avoid deformation.  

5. Please do not place it within reach of young children, and be careful not to let them play as there is a risk of burns.  

6. Be careful not to burn yourself when placing hot drinks in the cup.
