1. Cleaning
(1) Clean with a soft cloth and neutral detergent in warm water to avoid scratching the inner liner with steel wire balls.
(2) The gap between the cup lid can be wiped with a toothpick wrapped in cloth, and regularly soaked in baking soda water to remove odors.
2. Use
(1) Avoid storing strong acid/alkaline liquids (such as carbonated drinks, lemon juice) to prevent corrosion of the inner container.
(2) Do not store perishable liquids such as milk and traditional Chinese medicine for a long time, and clean them promptly.
3. Storage
Long term disuse requires thorough drying to avoid moisture causing odors or rust.
4. Other
(1) Handle with care to avoid collision and deformation that may affect insulation performance.
(2) Regularly inspect the sealing ring and replace it promptly after aging.
In summary, only proper cleaning and avoiding extreme use can keep the thermos cup as new for a long time.
