Reusing essential oil bottles that have contained aromatherapy oils or blends is possible; however, the fragrance of the oils will tend to cling to any bottle, regardless of the fact that it is plastic or glass. Therefore, you do not have to get rid of your essential oil bottles whenever you exhaust your essential oils, you can always reuse them with blends. Chances are that the oils may leave a sticky film on the inside of the plastic or glass bottles. The sticky film may be challenging to clean using soap and water, even if the water is boiled.
Cleaning Essential Oil Bottles
The most recommended way of cleaning the interior of an essential oil is by use of a solvent. A solvent will effectively dissolve any residue in the bottle. Rinse the bottles with rubbing alcohol to eradicate the presence of any residue, and then wash the bottles on the hottest cycle in a dishwasher. This process usually works, but it may not be successful with essential oil bottles that have contained the more intense oils, including jasmine and patchouli. Preferably, you should recycle used bottles, and put your next blends. Doing so prevents bacterial contamination. The most preferred alcohol you can use is vodka.
You can conveniently use less of your alcohol by filling your bottles half way. And letting them soak the alcohol for at least twenty four hours. You can always reuse your alcohol, especially if the bottles you just cleansed were containing less intense essential oils.
At times you can also reuse the alcohol as a fragrance if the bottles you have cleansed were containing concentrated essential oils. It is advisable to use a cleaning brush, specifically designed for cleaning bottles. Such a brush will make it easier to remove any sticky residue from your bottles. However, you should always remember that both alcohol and the essential oil residues are inflammable. And you may want to take serious precautions when cleaning.
You are urged to remember to get rid of old labels from your essential oil bottles. The easiest way of getting rid of the labels, even the most stubborn ones, is by soaking them in alcohol. Apart from the labels, you need to soak as well as clean the caps. You can reuse dark glass bottles that previously held essential oils by giving them a good cleansing. You should sterilize your dark glass bottles in the same way you would sterilize baby drinking bottles.
