Because there are many kinds of volatile oil components in Folium Artemisiae Argyi, it will produce tar in the combustion process, and then it will adhere to the inner wall of moxibustion box together with smoke particles, forming black viscous oil fume. Moxibustion box needs to be cleaned regularly, otherwise it will affect the heat and curative effect. Moxibustion pot cover should also be cleaned regularly to reduce the smell of oil dirt and smoke dirt. The specific cleaning steps are as follows:
1. Put the dirty box into the pot, add clean water (preferably rice washing water) and soak for a while.
2. Add baking soda, depending on the amount of moxibustion box to be cleaned.
3. Add vinegar, depending on the number of boxes.
4. Bring the fire to a boil, turn it down for 20 minutes, stir for a while, and pour out the dirty water.
5. Repeat the same method once. You can put less baking soda and vinegar in the second time, and it will be basically clean after cooking. If it is not clean, gently wipe it with a rag. After wiping, wash with clear water. If there is a strong tap water pressure, it can be washed directly with the tap after cooking, which is more convenient and quick.
