1. Wash the bought live clams with tap water first, find a small iron basin or plastic basin, put a handful of clams in the basin at a time, and then bump the small basin up and down to make the clams in the basin bump up. Put the bumpy clams in a clear water basin, and the water must drown the clams. Then add a small amount of salt, then drop four or five drops of sesame oil into the basin and let it stand for three to four hours, and the sand in the mussel can be basically removed.

2, rice water removal method. Soaking Meretrix meretrix in rice washing water for one or two hours also has certain effect, but only for Meretrix meretrix with less sediment.

3. Edible alkali soaking method. This method is the same as soaking in edible salt, the dosage of edible alkali and edible salt is basically the same, and the soaking time is the same.
