What you'll learn in this module

  • The most common mistakes when applying these three processes
  • How contact time affects how well a disinfectant works
  • A quick-reference summary to take away
  • Where to go next to build on this knowledge

Common mistakes to avoid

Mistake 1

Skipping the clean step before disinfecting

Organic matter such as grease, soil and bodily fluids neutralises many disinfectants before they can work. Always clean first.

Mistake 2

Not allowing contact time

Disinfectants need time on the surface to work, known as contact or dwell time. Wiping straight away means it hasn't had time to kill pathogens. Check the label for the required time.

Mistake 3

Using a sanitiser when a disinfectant is needed

Sanitisers reduce bacteria but may not be effective against viruses or every pathogen. In healthcare settings or during an outbreak, use a disinfectant.

Mistake 4

Diluting products incorrectly

Over-diluting a disinfectant drops it below the level it needs to work. Under-diluting wastes product and can damage surfaces. Follow the manufacturer's dilution instructions exactly.

Mistake 5

Assuming "antibacterial" means "disinfectant"

Antibacterial products target bacteria only. Disinfectants act on a broader range, including viruses and fungi. In high-risk situations, check the product's kill claims before use.

Quick reference summary

Process What it does Typical use
Cleaning Removes dirt and debris All surfaces, always the first step
Sanitising Reduces bacteria to safe levels Food prep surfaces, lower-risk areas
Disinfecting Kills a broad range of pathogens Washrooms, clinical areas, outbreak situations
You've completed Disinfecting vs Cleaning vs Sanitising. Well done.

You now know what each process does, when to use it, and the mistakes that stop it working.
