How to clean crabs:

Material preparation: salt, white wine, toothbrush, 45 degrees warm water, water, a pot of crabs.

The first step: pour a proper amount of 45-degree warm water into the basin with crabs.

The second step: then pour a proper amount of salt into the basin (salt can promote the crabs to expel the sediment from their bodies).

Step 3: Pour white wine into the pot (white wine can kill bacteria and parasites on the surface of the crab).

Step 4: Use a toothbrush to scrub the crab's abdomen.

Step 5: Use a toothbrush to scrub all the leg crevices of the crab (the crab's leg crevices are prone to harbor dirt).

Step 6: Finally, rinse the crab with water.
