Step 1: Clean the Water Reservoir

  • Remove the water reservoir from the unit, remove the black reservoir valve by pushing on it from the bottom. Clean the valve by massaging it under warm water for 30-45 seconds and set aside.
  • Place the reservoir in  your dishwasher for cleaning. We recommend air drying instead of a heated dry cycle.
  • If you removed the valve, place it back in the reservoir before use 

Step 2: Clean the Internal Parts

  • Mix 2-4 tablespoons (1-2 ounces) of white vinegar with 16 ounces of warm water.
  • Fill the reservoir with the solution, and then run 1/2 of it through the Water Flosser.
  • For countertop models, with the unit off, place the WaterJet Flosser handle in the sink and allow the solution to gradually drain out the handle for 20 minutes.
  • Run any remaining solution through the unit and then rinse with a full reservoir of warm water.

Step 3: Clean the Handle (Countertop Models)

  • Remove the tip from the unit using the eject button.
  • Soak the WaterJet Flosser handle in a container of white vinegar for 5-7 minutes.
