If you're like myself, cleaning likely isn't your favorite activity to engage in. That being said, I'm sure neither is throwing away a product that just didn't seem to last as long as it could have. This is why cleaning and maintenance is an important part of owning something that we've invested our money in and would like to get as much life out of the product as possible.

In this article we will take you through the steps of cleaning waterpik water flossers and removing hard water deposits, whether it's a cordless or countertop model. This will help to ensure your water flosser stays in good condition, and to prevent mold and other bacterial contamination so that it doesn't end up in the bin sooner than expected.


Soft cloth


Mild non-abrasive cleanser

A little bit of your precious time


Note: The following are general cleaning instructions. Always read the provided manual for each individual water flosser in case specific cleaning instructions are given.

STEP ONE: Caution

Never immerse the unit in water.

STEP TWO: Before You Begin

Unplug the unit from the electrical outlet before beginning any cleaning.


Periodically clean the unit with a soft cloth and mild non-abrasive cleanser. A good time frame for this would be weekly with regular use.

STEP FOUR: Dishwasher

Depending on the model, some parts may be safe to clean in the top rack of the dishwasher. Check the manual to make sure. If placing the reservoir in the dishwasher, remember to remove the valve prior to doing so and then replace it once the dishwasher cycle runs through. The valve can be cleaned by massaging under warm water for 30 to 45 seconds.


Mineral build-up can occur over time when the water you use in your flosser is hard; meaning high in dissolved minerals such as calcium and magnesium. These deposits can be difficult to remove and require more than simply soap and water.

In this tutorial we are going to use vinegar. A vinegar/water solution is very effective in removing mineral build-up. If you are interested in the scientific explanation, here it is: The acid in vinegar crosses the cell membrane of bacteria which then releases protons and kills the cell(s). The acid is also effective in breaking down grease.

Here are some steps to removing hard water deposits from your oral irrigator:

STEP ONE: Vinegar/Water Solution

Start by adding approximately 1 to 2 tablespoons of vinegar (depending on the size of the reservoir) to the reservoir filled with warm water.


Set the pressure to the highest setting and point into a sink. Turn it on and let half of the water from the reservoir empty into the sink. If using a countertop model, allow any remaining solution to drain out of the handle and into the sink for 20 minutes with the unit turned off.


Refill the reservoir with warm water once again and run it through the tip into the sink until completely empty.


If additives such as mouthwash or other solutions are added to the reservoir, perform step #3 under 'removing hard water spots' to give it a good rinse and avoid leaving residue behind.


It is recommended to replace water flosser tips every 3 to 6 months. They can also be affected by minerals deposits, so If you want to keep them clean and unclogged in the meantime watch this video for some tips on cleaning tips:
