1. Basic cleaning

Rinse the used vacuum flask with hot water or add a little detergent to clean it. You can use a brush

for cleaning the vacuum flask because the texture of the brush is soft, so as not to damage the coating.

2. When a peculiar smell occurs

Add diluted vinegar to warm water and soak for 30 minutes, then rinse with hot water two to three

times until the peculiar smell is removed. The same method can be replaced with rice water, a few

sugar cubes (without adding water), or rinsed with green tea leaves, which also has a good effect!

3. When tea/coffee stains appear

Use edible baking powder, add a little warm water, and brush with a cleaning brush to remove most

of the tea or coffee stains. Remember not to wipe too hard to avoid damage to the coating.

4. It can also be used to remove ordinary tea/coffee stains

Put the small ice cubes to a quarter of the height of the thermos cup, then add 2-3 tablespoons of salt,

close the lid, and shake well for a few minutes. Pour out the ice cubes and rinse them with warm water

to take away the stains!

5. When cleaning super stubborn stains

Add about one spoon of white vinegar to the thermos cup, then add 1-2 tablespoons of edible baking

powder and immediately add boiling water. At this time, bubbles will emerge. Cover the lid and place

it in the sink. Pour out after a few hours Then wash it off with warm water.
