1. First, pour a small amount of white wine into the crab bucket to remove the fishy smell.

2. When the crab is slightly comatose, pump it hard, preferably with the back of a spatula, until it passes out.

3, this time is the best time to start, quickly grab its back with your hands and lift the crab to a horizontal position with your chin. This position has the best angle of view.

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

5. Don't think about brushing a crab when brushing, imagine brushing 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 clean water.

The second type:

1. Prepare a pot of warm water at about 45℃ first, that is, just put your hands in the water and don't feel hot (the feet of crabs will fall off if they are too hot). Put the crab bellies into the water one by one, wait for it to turn over, and when it comes over, it has fainted after drinking hot water. The advantage of this is that the crab just fainted, and it won't let you pinch your fingers, nor will it affect the delicious taste of the crab.

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

4, the next step is the most critical, grasp the double pliers (use the toothbrush handle to pick up the joints of the double pliers from bottom to top, and use the crab's thumb and forefinger to grasp 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 belly cover and squeeze out the excrement from the inside out.

5. Finally, clean the dirt and crab tongs in the crab belly cover, so that the crab is clean.
