1. Place iron utensils

Put the snails in a basin filled with clean water, and then put a few iron utensils into the basin, such as kitchen knives, spatulas, etc. The snails will smell the iron utensils. The smell will spit out the mud. When frying, remember to cut off the tip of the tail and then wash it.

On the next day, you can find that these iron tools are covered with snails. Not only is there a layer of mud spitted out by the snails on the bottom of the basin, but the mother snail also gives birth to many snail babies.

2. Soak in salt

Put the snails you bought into a basin and simply wash them with clean water several times. Then add enough salt into the clean water until you feel that the water is very soft. Just make it salty. The snails in salt water will desperately absorb water and spit out mud due to the stimulation of salt. Soak for about 4 hours. You must change the water once, then add some salt and continue soaking.

Observe whether the snail will vomit sediment again. If the water is still dirty after a few minutes, it means that the snail has not vomited it out yet, and then soak it. If the water is clean, it has been spit out.
