Free taster micro-course. This is a short introduction to the topic, not full professional training. For in-depth courses with assessments and certificates, see the CCMTec® Academy.

What you'll learn in this module

  • When cleaning alone is enough
  • When sanitising is the right process
  • When disinfecting is required
  • Real-world scenarios across common cleaning environments

Choosing the right process

The right process depends on the environment, the surface and the level of risk. Using disinfectant everywhere isn't always necessary, and it can be wasteful and costly. Using only a detergent in a high-risk area is a health and safety failure.

Cleaning a toilet in a public washroom Clean then Disinfect
Cleaning a surface after a bodily fluid spillage Clean then Disinfect
Cleaning a clinical area or isolation room Clean then Disinfect
Wiping down gym equipment between users Clean then Sanitise
Cleaning a classroom at the end of the school day Clean
Cleaning during a norovirus outbreak Clean then Disinfect
The golden rule: always clean before you sanitise or disinfect

Dirt and organic matter on a surface greatly reduce, or completely neutralise, sanitising and disinfecting products. The clean step is never optional when a higher-level process follows.
