I thought sterilising was preferable over sanitising, but to be honest I’m not sure if that’s fact or just something I made up.
Sanitising is a process that destroys microorganisms, reducing the numbers present on
a surface to a safe level. This is usually achieved by the use of both heat and water, or by
specific sanitising chemicals (detergents are generally not sanitisers).
Sterilising is a process designed to destroy all microorganisms including microorganisms that have
formed a protective coat (spores). The standards do not require eating and drinking utensils and food
contact surfaces to be sterilised.
