Cleaning vs disinfection: what medical centres need to know

Why cleaning and disinfection are separate steps, why contact time matters, and what to look for in a cleaning provider for a clinic or medical centre.

Key takeaways
  • Cleaning removes dirt; disinfection kills pathogens
  • Disinfectants don’t work properly on dirty surfaces
  • Contact time on the label must be followed for disinfection to work

In healthcare settings, “cleaning” and “disinfecting” are often used interchangeably. They’re different steps, and both matter.

Cleaning removes

Cleaning uses a detergent and physical wiping to remove dirt, dust and organic matter like body fluids. It reduces the number of germs but doesn’t reliably kill them.

Disinfection kills

Disinfection uses a product designed to kill pathogens on a surface. It only works properly on a surface that has already been cleaned, because organic matter can shield germs and reduce how well the disinfectant works.

Why contact time matters

Every disinfectant has a contact time on its label: how long the surface must stay wet for the product to work. Wiping it straight off means it may not have done its job.

What a good process looks like

  1. Clean with detergent to remove soil and organic matter
  2. Apply the disinfectant to high-touch and clinical surfaces
  3. Leave it for the full contact time
  4. Record what was cleaned, when and by whom

What to ask a provider

  • Do you separate cleaning and disinfection steps?
  • Which products do you use, and what are their contact times?
  • How is each clean recorded?
  • How are staff trained?

Our commercial cleaning includes a documented disinfection service for clinics and medical centres.

Frequently asked questions

Can one product clean and disinfect?

Some products are labelled for both, but on visibly dirty surfaces a separate cleaning step first is still best practice.
