Reusing Essential Oil Bottles
Reusing Essential Oil Bottles
Most
essential oils are stored in amber or cobalt glass bottles. Once
I finish a bottle of essential oil or absolute, I try to clean and
reuse these glass bottle whenever possible.
Essential oils and absolutes vary
in viscosity (thickness). They can leave a sticky film on the inside
of your glass bottles that can be impossible to clean with just
soap and hot water. Sterilizing/bioling them also doesn't always
get rid of all essential oil residue.
The trick to cleaning the inside
of glass essential oil bottles is to use a "solvent" that
will dissolve the essential oil that remains in the bottle. High
proof vodka is readily available and is a good choice to use as
a solvent. Rubbing alcohol might work, but I prefer to use high
proof vodka for this. To conserve on vodka when cleaning larger
bottles, fill the bottle at least half way, and let it sit for a
few days. Every few hours or so, shake the bottle very well (with
cap on). Fill small bottles completely (no need to shake).
Depending on how "gunky"
the bottles are that you are cleaning, you can reuse the vodka to
clean additional bottles. Do not consume the vodka mixture when
you're done. When I clean out the bottle of a more precious essential
oil or absolute, I sometimes strain and reuse the vodka afterwards
to make an air freshener spray.
Using an appropriately sized bottle
brush can help loosen sticky essential oil residue. Be careful not
to let the mixture splash out of the bottle. You don't want to get
the vodka or essential oils in your eyes.
You can remove old labels from your
essential oil bottles as you would any other labels that you come
across. Soaking the exterior of the bottles in high proof vodka
helps to get rid of stubborn labels.
Be sure you also thoroughly clean
and soak the caps as well.
Amber or cobalt glass bottles can
also be sterilized in a manner similar to that of sterilizing baby
bottles. I don't usually bother with sterilizing them since I only
reuse bottles for particular diffuser and other blends that don't
require especially pristine storage conditions (see below).
Tips/Ideas:
- I never use recycled bottles to store more precious oils or
oils that I intend to specifically use for topical or therapeutic
purposes. I tend to "downgrade" the bottles that I clean
and reuse to only store blends intended for my diffuser or for
blends that I use for laundry or cleaning purposes. I avoid reusing
bottles for precious, topical or therapeutic blends.
- If a bottle originally contained an essential oil that is considered
sensitizing to the skin (i.e. cinnamon), play it safe and don't
reuse the bottle to store an essential oil that you plan to use
for topical blends.
- If a bottle is especially sticky and will cost more in vodka
to clean than the bottle is worth, I'll set it aside for recycling.
