Method 1: The scales of hairtail stick firmly to the fish, which is not easy to clean by rubbing with hands, and it takes time to scrape with a knife. If you put hairtail in water of about 80 degrees, scald it for 10 second, immediately immerse it in cold water, and then scrub it with a brush or cloth, the scales will be removed quickly. However, I suggest that you add some salt and ginger when cleaning, so that the freshness of fish will not be affected by foreign objects when cleaning. Hairtail has a strong smell and greasy taste, so it is difficult to wash it with clean water. You can soak hairtail in alkaline water first, and then wash it with clear water, which will make it easier to wash and have no fishy smell.

Method 2: Prepare a thin steel wire ball for washing dishes (generally available in this family), and cut a small ball (cut as much as you use and throw it away directly after use). After the hairtail is thawed in a basin, it is wiped with steel balls from beginning to end, and soon the white phosphorus will fall off. Then cut the hairtail, gut it and wash it.

Method 3: Prepare two pots, one pot of hot water (about 80 degrees) and one pot of cold water. First put hairtail in hot water, soak it for 45 seconds, then take it out quickly and put it in cold water. Do it quickly. You will find that a large part of fish scales fall off by themselves. Then gently rub it with your hand and the remaining scales will be washed clean.
