How should I clean the brushes ?

Hi Diana,Here is a simple cleaning process you can easily use:1. Pour 2-3 drops of essential oil in a bowl of water(room temperature). Don't overfill it. The level of the water shouldn't be higher than the height of the bristles. The wood should not get wet. The essential oil is antibacterial - you can use aegle, ageratum, citronella, eucalyptus, geranium, lemongrass, orange, palmarosa, patchouli or peppermint essential oil. )2. Place the brush (without the long handle) in the bowl, bristles facing down, such that only the bristles get damped, but not the wood. It helps to move the brush around in the water to get the essential oil mixed and running through the bristles. Do this for 1 minute.3. Repeat the above process, but this time using just water with no oil - to rinse the brush.4. Shake off any last excess bristles with your hand if necessary. 5. Take the brush out and dry it. You can use towels, let it just hang in sun or use the hairdryer. Some people say you can put it in your dryer, with your clothes, but I wouldn't expose it to humidity, even if it is low.You can use this 5 step cleaning process every once in a while, in order to clear any dead skin and kill the bacteria in the brush.Hope to hear from you soon with your impressions regarding our product!Kind regards,Melinda, Customer Experience Belula Care
