To clean essential oil bottles, you can use a small amount of rubbing alcohol and a dropper to clean the inside of the bottle. Simply add a few drops of rubbing alcohol to the bottle, shake it to coat the inside, and then use the dropper to remove any dirt or residue. Repeat this process as needed until the bottle is clean. Then rinse it with warm water and dry it before reuse. It's important to ensure the cap and dropper are also cleaned with the same method.
