Using Tips：When unfolding the travel cup, first remove the heat sleeve and then open the hole on the lid, so that it can be easily unfolded. When collapsing the travel cup, first open the hole on the lid, then collapse it and finally put the heat sleeve back in place.

In the dishwasher: Simply unscrew the lid and remove the heat sleeve, and you're ready to clean.
Note: Use natural, phosphate-free dish soaps.
They're better for the environment, and phosphorous can leave an unpleasant smell or taste in our silicone products.

By hand: Use a natural phosphate-free dish soap and water.
Make sure to let everything dry thoroughly before storing away.
For a super deep clean, make a paste using white vinegar and baking soda.
Apply the paste inside the cup, add boiling water, and soak overnight.
(The hard plastic lid and heat sleeve may warp inboiling water.)
Rinse thoroughly and you're ready to go!

With boiling water:
Disassemble the heat sleeve and lid, and place only the soft silicone cup in a pot of boiling water for 10 minutes.
Remove from water, allow to cool naturally, and dry thoroughly before using.
