First, wash the lobster several times with clear water, clean the dirty things on the surface, then refill it with clear water and soak it in salt or vinegar for about 2 hours to let the lobster spit out the dirty things. Salt water or vinegar water can effectively kill parasites and bacteria on the surface of lobsters.
Then prepare a clean toothbrush or small brush to clean the lobster. The dirtiest part of lobster should be the abdomen, because there are many folds in the abdomen, which are easy to get dirty and difficult to clean. You can brush the belly of lobster with a brush. If you have gloves, you'd better wear rubber gloves to avoid hurting your hands. Brush the belly of lobster repeatedly until the water becomes clear and blue shrimp meat can be seen.
The head of lobster contains the most heavy metals, and most of the internal organs of lobster are concentrated in the head, so the head of lobster should be removed before eating. But the lobster's shrimp yellow is also in the head, so when cutting the lobster head, it should be cut off at a 45-degree angle, leaving the shrimp yellow part.
Lobster intestines can also be dirty, so remove lobster intestines, that is, shrimp lines. In fact, removing the intestines of lobsters is very simple. Lobster tail has three parts. Twist around with the middle tail, and slowly pull it out, and the shrimp line will follow. So the crayfish were cleaned up.
