1. Soak the lobster in clean water to remove the sediment.

2. Hold the lobster from the back with one hand and turn the lobster belly outward.

3. With the other hand, insert a chopstick from the discharge port of the shrimp to the place close to the head, take out the chopstick, and then take it out to urinate.

4. Then open the lobster head. Clean out the gills on the head, and remove the stomach sac growing on the head and take out the brain marrow.

Rinse with clear water, and the lobster will be basically cleaned up.
