Cleaning vs Sanitising vs Disinfecting | Hygiene Direct NZ

Walk into almost any workplace and you will hear "clean", "sanitised" and "disinfected" used as if they mean the same thing. They do not, and mixing them up is one of the most common reasons a cleaning routine falls short.

Cleaning: removing the dirt

Cleaning removes visible soil, grease and food residue, usually with detergent, water and some scrubbing. Detergents lift dirt but do not kill bacteria. Cleaning can remove some microorganisms along the way, but that is not its job. Western Australia Health's food-business guidance makes the same point: cleaning is not intended to destroy microorganisms, and sanitising is what does that.

Sanitising: reducing germs to a safe level

Sanitising uses heat or chemicals to reduce the number of microorganisms on a surface to a level considered safe for the setting. The same guidance describes sanitisers as substances that can destroy microorganisms, including bacteria that cause food poisoning, and says that when used properly they reduce surface contamination to a safe level. In a food business, sanitising is the step that follows cleaning on food-contact surfaces.

Disinfecting: where the word gets slippery

Some guidance, including the page above, treats sanitising and disinfecting as the same step. Elsewhere, "disinfectant" is kept for products that make broader claims, for example against a wider range of microorganisms such as viruses. There is no single everyday definition, so the label and the supplier's documents matter more than the word on the front of the pack. If you need a specific claim, look for it in writing.

Why the order matters

Clean first, then sanitise. A sanitiser may not work as well on a surface that still has visible contamination on it, because dirt and grease get in the way. That is why guidance for food businesses treats cleaning and sanitising as two steps.

Step

What it does

Typical products

Disinfect

Disinfectant spray, disinfectant wipes

Where wipes fit

A ready-to-use wipe combines a little cleaning action with a sanitiser, which makes it quick and convenient for light soil and high-touch surfaces such as door handles, benchtops, switches and shared equipment. It does not replace a full clean on a surface that is visibly dirty. Wipe off heavy soil first, then use a fresh wipe to sanitise.

Wipes also need contact time. Sanitisers need time to work, and the time varies from seconds to minutes depending on the product, so follow the label. Our buyer's guide to commercial sanitising wipes explains what else to check.

Which do you need?

  • Daily wipe-downs of desks, handles and shared equipment: clean when visibly dirty, and sanitise with wipes or spray.
  • Food preparation surfaces: clean, then use a sanitiser that the label says is suitable for food-contact surfaces, following your food control plan or national programme.
  • After illness or contamination with bodily fluids: follow your site's procedures and use a product whose label makes the claims you need.
  • Healthcare, aged care and other regulated settings: follow your own infection prevention and control requirements for product type and claims.

Whatever you choose, keep the SDS for any hazardous product where staff can reach it. WorkSafe requires a current SDS for each hazardous substance in the workplace, whatever the quantity.
