1, prepare a small basin of clean water, add two spoonfuls of edible salt and appropriate amount of white vinegar to the clean water, stir well, and then pour the crayfish into the clean water for soaking. After about an hour, you will find a lot of dirty things in the basin, which is the performance of crayfish spitting out all the dirty things in their bodies. PS: This step can make crayfish soak in water for a while, but don't soak for too short, because it takes a certain time for crayfish to spit out the dirty things in their stomachs, and it doesn't play a big role if the soaking time is too short.

2. Hold the pliers of crayfish with one hand and hold a toothbrush with the other. After dipping in water, brush the whole body of crayfish. In this step, pay special attention to the belly and head of crayfish, because this is the dirtiest part of crayfish. Brush carefully along the lines. PS: When brushing the dirt on the surface of crayfish, be sure to control its pliers, so as to prevent the crayfish's pliers from hurting themselves, just like when turning crayfish.

3. After the crayfish is cleaned, continue to hold down its pliers, cut it diagonally at half of the head with scissors and cut off the head. In this way, the stomach of the crayfish was cut off by us. It should be noted that most of the dirty things in the lobster are stored in the stomach and shrimp line, so it must be disposed of.

4. Pinch the middle piece of the crayfish tail, twist it to the left first and then to the right, so that the middle piece will come down, and you can easily tear off the shrimp line by pulling it back along the curvature of the shrimp. At this time, a crayfish will be completely cleaned by us, and it will be very convenient to cook with it.
