Diffusers are the perfect tool to keep in your home or office. Depending on what essential oils you diffuse, they can freshen and cleanse the space with oils infused to meet your needs, which can range from calming and grounding, to invigorating and uplifting to the senses.

Learning how to clean your diffuser is important to ensure its longevity. If left for too long, essential oils or any leftover water can corrode and ruin your unit, and can also negatively affect your aromatic experience when there’s an array of essential oil residue in the diffuser.

To keep your diffuser in perfect running condition you should clean your diffuser after each use by wiping it out and letting it dry before using it again – I must confess im not so good at this step!

Every month, you should also give your diffuser a deep clean by following the steps below. Whilst this is specific for doTERRAs diffusers most diffusers will probably have similar instructions, if your not sure make sure to check with the manufacturer of your diffuser before trying to clean.
