Wash with a suitable amount of soap and

Although high-temperature sterilization
is possible, be careful as the sealing

of the pot.
Overtime, rust or water stains may
develop inside the tumbler due to water
quality, foreign substances, etc.
If this occurs, fill the tumbler with
about 90% hot water and 10% vinegar.
Let it soak for 30 minutes to an hour before
wiping thoroughly.
Since temperature resistance vary
depending on material, do not
wash at a high temperature.
Sterilize for 3 to 5 minutes in
boiling water.
To avoid damage, do not scratch
the tumbler's interior with any
hard objects.
Wash the exterior with lukewarm water and
a suitable amount of soap. After cleaning,
rinse off with water, then remove the
moisture with a dry cloth.
You can sterilize the tumbler by
placing it into boiling water or
disinfectant.
However, do not sterilize it with
high-temperature steam or water
for an extended period of time.
