First put the snails into a basin filled with clean water, and put some copper utensils into the basin, such as fruit knives, scissors, frying spoons, etc. If you smell the smell of copperware, you will spit out all the fine sand. On the second day, you will find that the copperware is covered with snails. Not only is a layer of soil spitted out by the snails sinking into the basin, but the mother snail will also give birth to many snail pups, which are usually cooked during frying. When cleaning, the tip of the tail should be cut off and then washed.

Soak them for about 4 hours, change the water once, then add a little salt, soak again, and observe whether the snails will spit out dirt again. For sand, if the water is still dirty after about 10 minutes, it means that the sediment is still not spit out and needs to be soaked again. If the water is very clean, it means that the sediment has been spit out.
