If the shellfish you buy are just soaked in clean water, the shellfish will only close their double shells tightly and refuse to open. If you put a little salt or vinegar in the water, the shellfish's stomach will be stimulated and they will spit out sand.

In addition, you can also put a knife or a piece of iron in the water where the shellfish are placed, which will also speed up the shellfish spitting out sand.

In order to prevent the sand spitted out by the shellfish from being sucked back by the shellfish again, the shellfish can be placed in the water filter basket during soaking, and then the water filter basket is placed on the water basin to allow the filter to drain. Keep water baskets four or five centimeters apart. In this way, the sand spit out by the shellfish will sink to the bottom of the basin and will no longer be sucked back by the shellfish.

(Method 1: Shellfish Soak shellfish such as clams, snails and mussels in water, and then put a kitchen knife or other iron tools in. The shellfish will remove the sediment. It usually takes 2 to 3 hours to spit it out; put the live loach into clean water and add a few drops of vegetable oil. After 1 minute, the loach can eliminate all the soil in its body; when washing yellow croaker, it is not necessary to perform a caesarean section. Just use two chopsticks to insert into the belly of the fish from the mouth, clamp the intestines and stir them a few times, then pull the intestines out, and then wash them.

Method 2: Put them all into one. In the basin!

Then add a little vegetable oil to the water! The part of the water covered by the vegetable oil will feel lack of oxygen in the water! This will achieve cleaning! If you want it to be cleaner, change the water several times! Just add enough vegetable oil, otherwise they won’t be able to breathe in it and they will easily suffocate! Experience! )
