First, after the essential oil is used up, use a piece of paper with good water absorption to put it on the bottle mouth, and let the bottle stand upside down for about a day. The remaining oil inside will also flow down.


Next, use the tweezers and then put on the blotting paper to wipe the inside of the bottle. Once again, and then wipe it again with the toilet paper, you can basically wipe off the surface.


Then use the detergent to pour the water, then pour it into the bottle, cover the bottle and shake it, then place it for about 15 minutes, pour it off, then add it again, after 3 times, rinse with water.


Finally, wipe the inner wall of the bottle with a paper towel, open the cover and put it in the window or in a ventilated place to ventilate it. If it is urgent, you can blow it directly with a hair dryer, not too hot.
