1. Prepare a steel ball for washing dishes (this family usually has it) and cut a ball (cut as much as you use, and throw it away after use).

2. After the hairtail is thawed in the basin, rub it with steel balls from beginning to end, and soon the white phosphorus will fall off.

Now let's get some dirty things in the head and stomach of hairtail, and then cut them off and wash them.

Precautions:

1, never use hot water of about 75 degrees for hairtail washing, because fish scales will melt when they meet hot water of 75 degrees.

2. Try to be careful when washing hairtail. Don't lose fish scales, and don't scratch silver scales on purpose.

The silver scales on the surface of hairtail have high nutritional value, but at the same time they also have a heavy fishy smell. This layer of silver scales will slowly oxidize when exposed to air for a long time, and the oxidized silver scales will turn yellow and have a "spicy taste". Such scales are no longer edible, so try to wash them off when washing hairtail.
