Regular cleaning ensures optimal performance and hygiene of your water flosser.

6.1 Cleaning the Water Tank

The detachable water tank can be easily removed and rinsed under running water. For thorough cleaning, it is recommended to detach the tank and wash it with mild soap and water, then rinse completely. Allow it to air dry before reattaching.

6.3 Storage

After cleaning, ensure all parts are dry. Store the water flosser in a cool, dry place away from direct sunlight. It is advisable to remove any remaining water from the tank before storage, especially for extended periods.
