Disinfection, according to the National Standards of Healthcare Cleanliness, is the process of eradicating or diminishing harmful micro-organisms from inanimate objects and surfaces. Sterilisation, on the other hand, pertains to the complete elimination of all micro-organisms, mainly reserved for critical items that contact sterile tissues or the bloodstream. Decontamination processes encompass cleaning, disinfection and sterilisation. In non-critical environments or with non-critical equipment, it generally refers to a two-step process involving separate cleaning and disinfecting agents or a ‘2 in 1’ product for simultaneous cleaning and disinfection.
