Spores are highly resistant to ordinary disinfectants because they have a tough protective coat and can remain dormant, so standard disinfectants that inactivate vegetative cells don’t reliably kill them. When spores could be present, you need a method that can actually inactivate or destroy them. Sterilization achieves that by eliminating all microorganisms, including spores. If sterilization isn’t feasible, you must use a chemical method that is proven sporicidal under the appropriate conditions (concentration, contact time, and environment) to ensure spores are inactivated. Regular disinfection targets only vegetative organisms and fails to reliably kill spores; heating at room temperature isn’t sufficient for pasteurization, and air drying does not decontaminate.
