How To Remove Oil From Glass Bottle. Most essential oils are stored in amber or cobalt glass bottles. Its going to be difficult to get a bottle brush into the bottle but that doesnt make it impossible to clean.

Oil isnt the easiest substance to remove from a glass surface but there are always ways to accomplish the job and some standard cooking and household items can be used to do it. Fill half way with hot water and add a handfull of sand. Swirl bottle until baking soda is dissolved.
The ones that I fill with oil I have a devil of a time cleaning them.
Water alone wont get the oil bottle clean because water and oil are such different liquids. Submerge the bottles in the bowl of water. I also put my hand on the top and shake vigorously. Remove as much of the label from the bottle that you can.
