Mineral deposits and other materials can collect in your Water Flosser, causing it to lose pressure and effectiveness.

Here are 4 steps for simple cleaning with water, vinegar, and your dishwasher to keep your Water Flosser performing at its best. Complete this process every 1-3 months to ensure optimal performance.

Step 1: Clean the Water Reservoir

  • Remove the water reservoir from the unit. (Refer to your product manual if you need assistance).
  • If using a countertop model WP-100/112 (Ultra), WP-260 (Kids), WP-300 (Traveler), WP-60/65 (Classic), WP-72 (Classic Professional), or WP-900 (Complete Care), 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 the top rack of 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. (Dome side up, push in place so the four prongs are visible on the bottom of the reservoir.)

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 Water 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 Water Flosser handle in a container of white vinegar for 5-7 minutes.
  • Rinse the handle under warm water.
  • Clean the Water Flosser tip separately using step #4.

Step 4: Clean the Flosser Tip

  • Remove the tip from the unit using the eject button.
  • Soak the Water Flosser tip in a container of hydrogen peroxide or white vinegar for 5-7 minutes.
  • Rinse the tip under warm water.
  • For maximum effectiveness over time, we recommend replacing Water Flosser tips every 3-6 months. The tips can become clogged and/or affected by mineral deposits.
