Follow these steps for cleaning after each use:

1) Drain any residue solution, then refill a small amount (2-5ml) of water and close the lid. Gently shake to remove any leftover residue. Repeat 1-2 times.

2) Pour a small amount (2-5ml) of hot water (30°C or 86°F) into the medicine bottle and close the
cover
3) Hold the power button down to put the device into cleaning mode, let it run for 1-2 minutes to remove residue from mesh holes (the device can clog and not produce mist if you don’t clean off the residue)
4) Rinse the medicine bottle and cap with water and gently wipe with a clean cloth, including the front nozzle (you can use a tissue or cottonpick to reach the mesh), then allow the parts to fully dry ina clean environment.

5) Rinse the masks and mouthpiece under warm or hot water, to clean off any residue there too
