Of all the options to sterilize (killing or eliminating all microorganisms, which includes the spores of bacterial growth) moist heat that is saturated steam with pressure has been the most frequently utilized and most reliable method. Moisture has more penetrating power than dry heat, and at a certain temperature, causes a greater reduction in the quantity of live microorganisms. Steam sterilization is safe cheap, low-cost, quickly microbicidal, as well as sporicidal. It quickly heats and penetrates into fabrics.
