Giải thích
Dry heat at about 320°F for one to two hours sterilizes without moisture, which protects carbon steel from corrosion and dulling. Surface disinfectants and alcohol wipes are not sterilants and cannot be used on instruments that penetrate tissue. Hot tap water and air drying accomplish neither cleaning nor sterilization.
