With the continuous improvement of living standards, the stainless steel insulation cup plays an increasingly important role in our daily life, so its maintenance is very important.

Before use, please clean the inside of the product and preheat it with hot water for 1 ~ 2 minutes to increase the temperature inside the insulation cup properly, which can better improve the insulation effect. Too little or too much water will affect the insulation effect. The best insulation effect is 1-2CM under the bottleneck. The content of the lunch box should not be too small or too much, and the best capacity is three-fourths or four-fifths of the content. After pouring water, tighten the bottle cap slowly and firmly to prevent water leakage. When using, please pour a spoonful of soda into warm water from time to time, sterilize with the lid open, and then wash thoroughly with warm water. Cleaning the cup with edible vinegar once a month is very beneficial for hygiene and long-term use. When cleaning, you can dilute 1-2 drops of edible vinegar in warm water, pour it into a thermos cup, open the bottle cap for 30 minutes, and then wipe it with a soft cloth. Vinegar washing is very effective for cleaning fine particles and bacteria.
