The bought live crabs should be washed with clear water first, then soaked in light salt water for a period of time, so that the crabs can spit out the dirty things in their stomachs. Pay attention to changing more water during soaking until the water spit out by crabs is clean.

Step 2 brush crabs

When the crab spits out the pollutants in its stomach, it is necessary to start scrubbing the crab with water. When scrubbing, be careful not to have too much water. Brush crabs with a toothbrush, and use force when brushing.

3. The specific steps of brushing crabs:

Brush the side, back, abdomen and mouth of the crab first, then brush the feet and the roots of the crab pliers.

The belly cover of crab is the key part to be cleaned, because there are many pollutants and excrements in the belly cover. Before cleaning, the excrement in the abdominal cover is squeezed out first, and then the dirty things in the abdominal cover are cleaned up with a brush.

Finally, brush crab claws and rinse them with water.
