Pricing depends on facility size, scope of work and cleaning frequency. Surgical suites or treatment rooms often require medical-grade protocols, which can affect cost.

Disinfectants such as bleach or hydrogen peroxide eliminate bacteria and viruses. Detergents remove dirt and organic matter. Enzymatic cleaners break down biological contaminants, and alcohol-based solutions provide rapid surface disinfection.

The four main categories of cleaning are:

• Cleaning – Remove visible dirt and debris.
• Disinfection – Killing bacteria and viruses on surfaces.
• Sterilisation – Elimination of all microorganisms, including spores.
• Sanitisation – Reducing microorganisms to safe levels for general use.

Sterile means the complete absence of microorganisms, achieved through sterilisation. Medically clean means surfaces have no visible dirt and most germs are reduced, but not completely gone.

Cleaning removes dirt and organic matter with water, detergents and agitation. Sterilisation is a process that kills all microorganisms. This includes bacteria, viruses, fungi, and spores. Common methods are autoclaving and chemical sterilants.
