Misconceptions about Using Stainless Steel Insulated Cups: You Might Be Constantly Hurting Your Cup

Many people use stainless steel thermos flasks every day, but they are accidentally hurting them in the wrong way. Avoiding these common misunderstandings can keep your thermos cup with you for a longer time.

Taboos for serving beverages
Carbonated beverages can generate pressure, causing the lid to pop out. Milk is prone to spoilage and develop an unpleasant smell. Traditional Chinese medicine may corrode the inner wall. Long-term storage of acidic fruit juice can affect its quality. Thermos flasks are best suited for clear water, tea and coffee.

Attention should be paid to the cleaning method
Avoid scrubbing with a steel wool ball, as it may scratch the inner wall. Bleach and strong alkaline cleaners may damage the surface of stainless steel. Long-term soaking will cause scale to form. It is recommended to clean with a soft cloth and neutral detergent.

There are certain rules for storage methods
When not in use for a long time, it should be thoroughly dried and stored to avoid unpleasant odors caused by a damp environment. Do not store the cup upside down, as it may cause the sealing ring to deform. Avoid storage environments with high temperatures or direct sunlight.

Adjustment of usage habits
Do not store ice cubes in a thermos for a long time. A large temperature difference will affect the sealing performance. Avoid falling from a height, as it may affect the vacuum layer even if the appearance is undamaged. Regularly inspect the cup lid parts and replace the aged components in a timely manner.

The wisdom of maintenance and repair
When slight leakage is detected, you can try adjusting or replacing the sealing ring. Spots on the inner wall might be scale. Just soak it in a diluted vinegar solution. Small areas of paint peeling can be repaired with a special touch-up pen.
