So, how do you clean your bottles? A question asked often.
They must be sterile before adding different oils to a bottle, unless you refil like with like (then sometimes that can change, depending on the ‘batch’ of oils).
So it goes like this:
1. Wash your bottle in warm soapy water (natural dish-dergent)
2. Boil bottles in a pot of boiling water for at least 3 minutes.
3. Oven dry
Now your bottles are ready to recycle.
