1 Tools for cleaning small crabs: When cleaning small crabs at home, you need to prepare a toothbrush and a basin, as well as appropriate amount of water.

2. Soak the crabs before cleaning them. If you want to wash the crab easily, you must put it in a basin and soak it in water before cleaning. The soaking time should be about 20 minutes to half an hour.

3. Wash the small crab with a toothbrush. After soaking the crab in clear water, grab its sides by hand, wash its back, abdomen and mouth with a toothbrush, and then clean its sides and feet. At this time, most of the small crabs are alive. If you are afraid of being caught by it, you can change the soaked water into warm water of about 50 degrees, so that the small crabs will faint when soaking, and they will no longer be aggressive.

4. Final cleaning. After brushing all the crabs with a toothbrush, replace the water in the basin with clean water, put the crabs in the basin, soak them for ten minutes again, and then wash them with clean water. At this time, all the crabs are washed clean and you can eat them as you like.
