Close the lid securely in level position
Close the lid securely making sure that it is not slanted. You can turn the lid counter-clockwise to find its level position. When carrying your tumbler, keep it upright just to be safe.

2) Fill the tumbler with the liquid from step 1. Disassemble the lid and silicone ring, and soak in the liquid from step 1.
3) Soak for about 1 hour, wash well, and dry. If there are any remaining stains, rub with a soft sponge.
*Baking soda can also be used. Dissolve 25g (approx. 2 tablespoons) of baking soda in warm water and follow the same steps as above.
