1.Self-made scaling brush: find a board, and determine the size of the board according to the convenience of use. Pick up some iron beer bottle caps and nail them on the board, usually in 3-5 rows. In this way, the self-made scaling brush is made. It is especially useful to scale large scales of carp, herring and other fish. It is equivalent to buying a simple scaling machine.
2. It's easy to scrape scales with vinegar: when scraping scales, put two tablespoons of vinegar in the cold water where the fish are put, soak the fish for two hours, and then clean it with a self-made scaling brush.
