1. First, pour a small amount of white wine into the bucket where the crabs are placed to remove the fishy smell, just the right amount.

2. When the crabs are slightly comatose, smoke them hard, and it is best to use the back of the spatula until they are stunned.

3, this time is the best opportunity to start, quickly grab its back with your hands and lift the crab to a level position with your chin. This position has the best perspective.

4. Temporarily put down the spatula, pick up the brush and brush it toward the flat crab abdomen.

5. When brushing, you shouldn't think about brushing a crab, but you should imagine brushing leather shoes, and don't miss every corner.

6. After checking that there is no silt, throw it into another bucket and wake them up with clear water.

The second type:

1, first prepare a pot of warm water at about 45℃, that is, just put your hands in the water and don't feel hot (the crab's feet will fall off if they are too hot). Put the crab belly up into the water one by one, wait for it to turn over, and when it comes over, it will have drunk hot water and fainted. The advantage of this is that the crab just fainted, and it won't pinch your fingers at your mercy, and it won't affect the delicacy of the crab.

2. Take out a toothbrush, grab both sides of the crab and wash the back, abdomen and mouth with a toothbrush. 3. Then clean the sides of the crab and the roots of the feet and pliers.

4, the next step is the most critical, grab the double pliers (use the toothbrush handle to pick up the joints of the double pliers from bottom to top, and use the thumb and forefinger of the crab to grab the crab pliers along the root of the pliers. Individual fierce crabs can first press the pliers down a few times or knock a few times) to open the abdominal cover and squeeze out the excrement from the inside out in the middle.

5. Finally, clean the dirt and crab pliers in the belly cover of the crab, so that the crab is cleaned.
