Why is 70% alcohol a better disinfectant than 95 alcohol?

What Cannot be sterilized in an autoclave?
A medical autoclave is a device that uses steam to sterilize equipment and other objects. This means that all bacteria, viruses, fungi, and spores are inactivated. … Because damp heat is used, heat-labile products (such as some plastics) cannot be sterilized this way or they will melt.
Does sterilization kill viruses?
A sterile surface/object is completely free of living microorganisms and viruses. Sterilization procedures kill all microorganisms. Methods used in sterilization procedures include heat, ethylene oxide gas, hydrogen peroxide gas, plasma, ozone, and radiation.
