How do I use and maintain my electric essential oil diffuser ?

 After several uses, your essential oil diffuser may become clogged or even stop working properly.

To make the most of the benefits of your diffuser and avoid any breakdowns, it is important to follow the maintenance instructions in the leaflet supplied with your appliance carefully. If your diffuser is not maintained correctly, it could be damaged and not last over time.

Please note ! Each diffusion technology has its own particularities, so we advise you to adapt your maintenance to the category of diffuser in your appliance. As gentle heat, ventilation and misting technologies require very little maintenance (simply wipe regularly with a soft damp cloth after each use or change of essential oil), we will focus below on nebulisation technology.

Rules for using an essential oil diffuser

fill a diffuser glass1 - Only use pure essential oils (not diluted with alcohol, water, vegetable oil, etc.).


2 - The essential oil level must never reach the end of the two nozzles (black line in the photo).

If the essential oil exceeds this level, you risk destroying the engine through essential oil backflow. Warning : This phenomenon is not covered by the warranty. A diffuser works perfectly well with a small amount of essential oil (1 cm is enough). So avoid overfilling it.

3 - Plastics don't like essential oils very much, so we advise you to wrap a "handkerchief" around the neck of the glassware when filling. This will limit drips onto the bonnet and especially onto the black support. Warning : Damage caused by essential oils is not covered by the warranty.

4 - It's better to diffuse a little, but often (a timer can be useful).

The order of magnitude for our models covering rooms of 50 m2 and 120 m2: about 30 minutes.


5 - Don't let your essential oils dry out in the glassware, especially citrus fruits. Diffuse regularly or clean your glassware.

6 - Dismantle and reassemble the glassware from its support :
a - If the air supply is via an external hose :
- Never undo the hose on the pump side (risk of breaking the plastic end on the pump side).
- Never push the hose in more than 5 mm on the glassware side (risk of breaking the glass connector when pulling the hose out. If it is pushed in too far, the hose will have to be cut with a cutter).

b - If the air inlet is at the bottom of the glassware :
Whether inserting or removing your glassware: Insert the foot of the glassware into the rubber ring in the centre of the pump. To do this, make sure you secure the glassware by gently pressing it vertically back and forth from left to right while pinching the rubber ring with your other hand.

This rule is important because if you remove and insert your glassware while rotating 360°, the inner tube connecting the glass to the turbine will twist and pinch, preventing the air from escaping. The pump makes noise as it forces but no longer emits enough air to dispense. Sometimes the pressure is so great that it wears out the turbine to the point of rendering it inoperative. 

Essential oils for use in an electric diffuser

In practice, all essential oils, if pure, can be used in a diffuser. However, some should be avoided (see the list in our special report "Diffusing essential oils".


Be careful where you buy them !
Be careful where you buy your essential oils

Be careful where you buy your essential oilsSome customers contact us after a few weeks or months and complain that the glass in their diffuser is clogged. Most of these customers did not buy their essential oils from us, but from somewhere else!

You can find very good quality essential oils on the market, but you can also find bottom-of-the-range products.

A little vegetable oil in an essential oil can reduce the price, but it can also clog your glassware.

It is therefore preferable to buy organic essential oils, which undergo more controls and therefore offer a greater guarantee of quality.

All the essential oils you'll find on our site can be diffused without any problem. We've been diffusing our essential oils with the same diffuser for years, we never clean it and it's never clogged.

Be careful, however, with the regular use of citrus fruits (orange, mandarin, lemon, etc.) in a diffuser.

Remember that citrus fruits are not distilled but obtained by cold extraction of the zest. They are not essential oils, but essences.

They can of course be diffused, but as they are oilier, you'll need to clean the glassware in your diffuser regularly, or alternate with other essential oils (lavender, for example), which will clean your glassware.

If citrus fruit is not properly filtered, it can also contain fine particles in suspension. These particles can clog the glassware. 

Maintenance of diffuser glassware

There are several methods for cleaning glassware. You can choose one or the other depending on the degree of soiling.

cleaning glassware with 90° alcohol

1 - Cleaning with alcohol

We're obviously talking about 90° alcohol here (70° if you can't get hold of any). This method is best used if the diffuser glassware is not too "clogged" or if your oils have not yet set. Empty your glassware of the remaining essential oils, pour in 1 ml of 90° alcohol, then turn on your diffuser and allow it to diffuse until complete evaporation. Once the alcohol has evaporated completely, pour new drops of essential oils into the glassware. Be careful not to do the same with water.

2 - Cleaning with a degreaser

Start by draining the stagnant oil from your glassware.

Remove the glass from its diffuser base.

Pour in a drop of dishwashing degreaser and fill ¾ full with hot water.

Mix gently. Leave to stand for a few minutes, then rinse thoroughly.

Wipe with a soft cloth and run on vacuum to evaporate any remaining droplets.

Repeat the cleaning with rubbing alcohol if necessary.

3 - In-depth cleaning

Start by draining any stagnant oil from your glassware.

Soak your glassware in cold, temperate water and bring to the boil for a few minutes.

Allow to cool, then drain off the water (beware of the risk of scalding).

Wipe off with a soft cloth and run on vacuum to evaporate any remaining droplets.

Repeat the cleaning with rubbing alcohol if necessary.


Good to know : Residues left by citrus essential oils (orange, lemon, neroli, bigarade, grapefruit, tangerine) do not wash off with alcohol. To remove them, simply run the diffuser with lavandin essential oil, which is an excellent cleaner.

Have you run out of diffusers ?
Before saying that your diffuser has broken down, check that your glassware is not blocked or clogged.

Place your glassware in front of a light source and check the vertical inner tube, where the essential oils arrive. There should be no traces of colour (dried essential oil) or particles (citrus zest), and the tube should be completely transparent (see photo at the bottom of the page). 

Cleaning the Giffard system

If the diffusion becomes reduced or completely absent, you will need to clean the Giffard diffusion system from the glassware.

1 - Remove the glassware from its support. Caution :
a - if the air supply is via an external hose :
- Never undo the hose on the pump side (risk of breaking the plastic end on the pump side).
- Never push the hose in by more than 5mm on the glass side (risk of breaking the glass end cap when pulling the hose out. If it is pushed in too far, the hose will have to be cut with a cutter).

b - If the air inlet is at the bottom of the glassware :
Remove the base of the glassware from the rubber ring in the centre of the pump. To do this, gently pull the glassware vertically back and forth from left to right while pinching the rubber ring with the other hand.

2 - To thoroughly clean the Giffard system in your diffuser, you will need to use our glassware cleaner, which is the only effective product for dissolving congealed oils. The cleaning pipette will help you inject the cleaner into the injector in order to release the blocked particles.
3 - Fill your glassware to the brim with cleaner, place it in a glass (see photo) and leave the product to work for at least 12 hours.
4 - If you have cleaned your glassware beforehand, you can recover the product.
5 - Rinse your glassware well.

Cleaning tip

Start by draining the stagnant oil from your glassware.

With your diffuser running, pour a few drops of rubbing alcohol into the glass. Very carefully place a thin rod (e.g. a wooden skewer) at the mouth of the vertical nozzle, without inserting it, to radically expel the impurities towards the bottom, thus freeing the tube and allowing perfect fluidity once again. Repeat the operation, then discard the excess alcohol.

 

Bubbles in the diffuser glassware ?

Giffard system for diffuser glassware The Giffard system in diffuser glassware If you notice bubbles at the bottom of your glassware, this is generally due to a narrowing of the passage of essential oils through the central tube.

1 - If your diffuser has never been used before, it is likely that the tube has been welded too low : this is a manufacturing defect.

2 - If your diffuser has already been used, it is likely that a deposit of essential oils has formed at the bottom of the glassware. This deposit will prevent the oils from rising up the tube. You will need to clean your glassware.
