How to Properly Clean an Insulated Cup and Precautions for Use

Due to the popularity and convenience of insulated cups, they have become an indispensable part of daily life. This also raises people's thoughts on how to clean insulated cups and the precautions to take to extend their service life.

Daily Cleaning Steps:

3. Mix a special cleaning solution with clean water (warm water), close the lid, shake slightly, then pour out the cleaning solution.

4. Clean and wipe the inner wall with a soft cloth or brush.

5. After cleaning, rinse thoroughly with water to ensure no detergent residue remains on the inner wall.

6. If there is an odor in the cup, you can clean it with baking soda to remove the odor (of course, the editor thinks that if you like tea, you can brew a pot of tea to remove the odor, or if you like coffee, you can brew a pot of coffee to remove the odor).

7. Thoroughly clean with hot water or tap water to ensure the inner wall is clean.

8. If there is a rubber ring inside the insulated cup, remove it for separate cleaning, and clean it with a special cleaning solution to ensure no residue remains on the rubber ring.

Precautions:

2. Do not use chlorine-containing cleaning agents, as this will damage the inner wall of the insulated cup.

3. Do not put acidic or alkaline beverages in the insulated cup, such as carbonated drinks, lemon water, etc., as this will corrode the interior and accelerate the corrosion of the insulated cup.

4. Do not store acidic or alkaline medicines in the insulated cup, as they may react with the inner wall and pose a risk to the body.

5. Avoid hitting the insulated cup, which can cause the sealing ring to fall off and the insulation performance to deteriorate.
