Press the safety valve with the handle of a spoon or other hard object and check that the safety valve moves up and down. If it does not operate smoothly, wash the stopper with running water. (The safety valve is stiff. Be careful to avoid injury when pressing it.)

* Remove and wash.
Do not soak the main body, stopper, lid, or loop when cleaning them. (This does not apply to the gaskets.) There is a risk that water may enter the parts.
Be sure to attach the gaskets.
Dust adheres easily to the loop. Do not rub it with a towel or similar material while it is wet. Press and wipe the loop using a soft cloth.
After washing the main body, immediately use a dry cloth to wipe off the moisture. If all droplets are not wiped off, they may leave water stains, cause rust, or stain other items.
Do not use paint thinner, cleansers, bleach, cleaning wipes, metal scrubbing brushes, or nylon scrubbing brushes.
Do not use a dishwasher or dish dryer, or wash with boiling water. (This does not apply to the gaskets.)
If the product will not be used for a prolonged period, fully clean and dry it.
If marks start to become visible on the inside of the main body
When there are red, rust-like spots or a substance that is rough to the touch
Such staining can be caused by minerals in water, such as calcium, magnesium, and iron. When cleaning these substances, it is recommended that you use citric acid, which is available at supermarkets and drug stores.
Dilute the citric acid (approximately 10 g) with lukewarm water, then pour it into the main body.
After 2 to 3 hours have elapsed, wash the main body with a soft brush and then thoroughly rinse it.
Fully dry the main body.
When there are tea stains, coffee stains, or similar substance
The stains are caused by tannins and oil components contained in the beverage. The use of Tiger vacuum insulated bottle detergent (sold separately) is recommended. Click here to purchase consumable parts.
Depending on the beverage, the beverage odor may remain on the gasket. In this case, leave the gasket in boiling water for approximately 30 minutes to reduce the odor. If the odor is still a concern, please purchase a new gasket (sold separately). Click here to purchase consumable parts.
