Ensure proper attachment and condition of parts
Leakage can be prevented by attaching silicone rings in the proper direction. For details, please refer to this page for instructions on how to attach the silicone ring for each product series.
Wash and care
▼Daily care
Use a brush or sponge and wash with a neutral dishwashing liquid detergent. Dry well.
For straw-type spouts, we recommend using a fine brush and spray-type dishwashing detergent.
▼Removing Stains
We recommend soaking with oxygen bleach (powder type).
(1) Dissolve 3g (approx. 1/2 to 1 teaspoon) of oxygen bleach in 1 liter of warm water (40–50°C / 104–122°F).
(2) Pour the solution from step (1) into the tumbler. Soak the lid and silicone ring separately in the same solution.
(3) Soak for about 1 hour. Wash with dish soap, rinse thoroughly, and let dry.
*You can also use baking soda. Dissolve 25g (approx. 2 tablespoons) of baking soda in 1 liter of warm water and follow the same steps above.
▼Removing Odors and Rust
We recommend soaking with citric acid.
(1) Dissolve 3g (approx. 1/2 to 1 teaspoon) of citric acid in 1 liter of warm water (40–50°C / 104–122°F).
(2) Pour the solution from step (1) into the tumbler. Soak the lid, mouthpiece, and silicone ring separately in the remaining solution in a bowl.
(3) Soak for about 1 hour. Wash with dish soap, rinse thoroughly, and let dry.
For best results, first remove stains using oxygen bleach or baking soda, then follow with citric acid soaking.
<Please Note>
*Do not close the lid while soaking, as it may build up pressure and become dangerous.
*Do not use the following cleaning methods as they may cause deformation, leakage, and deterioration of the product:
- Washing in a dishwasher
- Sterilizing in boiling water
- Using chlorine bleach
If usability changes
Parts such as silicone rings and lids are prone to wear over time. Repeated use and prolonged contact with hot water may cause them to deteriorate gradually. We recommend checking the condition of the silicone ring about once a year. If it becomes loose or starts to leak even when properly attached, please replace it with a new one.
