1. First, put the purchased Pipi shrimp in clean water for a while, and let it spit out the dirt in its stomach. During this period, the water should be changed several times until the water becomes very clear. .

2. The next step is to wash the Pipi shrimps in a basin. Grasp the two sides of the shrimp with your hands, immerse its body in the water, and rock it back and forth to remove impurities from the shrimp.

3. If the shrimps are too fresh and you dare not catch them with your hands, you can use a large filter spoon to hold the shrimps in the water, and then change the water. Repeat this several times and it will be almost done.

4. In addition, we can also use a clean brush to scrub the shrimps one by one. After washing, soak them in clean water for 2 minutes, and then rinse them with clean water, and they will be almost clean. .
