Thwarts Oil Build-Up

There is a selection of oils that will leave some deposits after going through the diffuser cycle. After some time, the oil will begin to accumulate on the ultrasonic plate (if using an ultrasonic oil diffuser), the misting eyelet/hole, and even the lid. Consequently, this will affect the functionality of the diffuser because it won’t be releasing the appropriate stream into the air.

Prevents Unlikeable Aromas

When you get rid of the remnant oils inside the water reservoir, you prevent the combination of non-complementary aromas or accidental mixing of oils.

The Oil Diffuser Lasts Longer

Having a regular recurring routine to clean your diffuser is very important to ensure it lasts a long time for you to enjoy the benefits. If left for a long time without being cleaned, the leftovers of water and oils can corrode and damage your unit.

Protect the Warranty

Just in case your essential oil diffuser stops working within its first or two years (depending on the warranty period), you can take it back for replacement. Keep in mind the vendor will only exchange it if you’ve taken care of it appropriately.

How often should you clean your essential oil diffuser?

If at all possible, you should ensure to rinse clean your essential oil diffuser after every use, particularly if you’re altering the oil aromas. Then again, depending on the number of times you use your diffuser, you’ve got to carry out a deep cleaning at least every four weeks, to get rid of any build-up that can affect how the unit functions.
