How to clean purple sand tea cans?

Let me talk about it as a person who produces purple sand tea cans. I'll start by saying whether to clean it. It depends on the actual situation, which is what you get. Under normal circumstances, it is not necessary to wash the tea cans directly from our factory, because the tea cans are fired at a kiln temperature of about 1200 degrees Celsius, leaving only the dust on the basic surface, which can be wiped with a slightly wrung wet towel.

However, many people do not buy cans through this channel. If they buy from offline stores or other online dealers, the cans may get dirty in the process. For example, in offline stores, they will randomly pile up the dust accumulated for a long time, and even some stores will wax the cans to make them look good. Waxed jars are oily to the touch, but bright, much better than those without wax, just like their purple sand. Then network dealers will use foam for shock-proof packaging during the delivery process. Foam is particularly prone to debris, which will stick to the tank during transportation and be dirty. In both cases, it must be cleaned, not so clean. If it is waxing, it must be boiled for a long time, and the wax must be dissolved in water. This is more troublesome and the wax is exaggerated. This thing completely blocks the pores of purple sand, and I hate this technique. Then if there is a lot of debris or dust, just rinse it repeatedly with clear water. Finally, we must remember that purple sand absorbs water and must be exposed to the sun for more than 3 days after washing. Because after three days of basic exposure, the water in the teapot almost evaporated, otherwise, if there is still a lot of water in the purple sand, it will affect the storage of tea. In addition, I would like to add that it has nothing to do with the north. In the south, it is best to put the purple sand cans on the shelf. If you want to put it on the ground, you'd better put some cardboard or wooden strips on it to avoid direct contact with the cement floor. Because the south is humid, dew may be seen on the ground and walls when it comes to Huangmei day. A ripe purple sand teapot can protect the tea inside and play the role of moisture-proof and tea awakening.
