A different cleaning standard for a different kind of space
One of the biggest misconceptions about environmental cleaning is that the same products and techniques can be used across every workplace. In reality, hospital theatre cleaning is fundamentally different from cleaning in offices, schools, retail centres or hospitality businesses.
In most commercial settings, cleaning is about presentation: a space that looks clean, smells fresh and feels welcoming. In an operating theatre, the stakes are far higher. The goal isn’t just cleanliness, but the active reduction of microbial contamination and the prevention of healthcare-associated infections (HAIs). Every cleaning task must be carried out with patient safety as the non-negotiable priority.
The key takeaways
- Hospital theatre cleaning is fundamentally different from commercial cleaning because the priority is reducing microbial contamination rather than presentation
- Theatre cleaning begins the moment the last surgery ends and is one of the most critical stages of infection prevention
- Hospital-grade, TGA-approved disinfectants (and sometimes sporicidal products) are required, not general commercial detergents
- Hospital-grade disinfectants approved by the TGA are required in place of the general-purpose products used in most commercial cleaning
- Cleaning teams follow a structured technique and wear additional PPE to meet stricter infection control requirements
When theatre cleaning begins
When the final surgery of the day is complete and the operating theatre falls quiet, one of the most important stages of infection prevention begins. This is theatre cleaning, often referred to as terminal cleaning, and it carries the same weight as any procedure that took place in the room that day.
While surgeons and clinical staff have finished their work, our cleaning professionals step in to prepare the theatre for the next day’s procedures. Theatre cleaning is far more than a routine housekeeping task. It is a systematic process designed to eliminate contamination from every surface within the operating theatre, scrub bays and anaesthetic rooms, reducing the risk of HAIs and supporting the environmental cleaning requirements set out in the Australian Guidelines for the Prevention and Control of Infection in Healthcare, which forms the basis of infection prevention and control practice in hospitals across the country.
How it differs from routine cleaning
Between cases, cleaning is fast and targets extreme risk areas, with tight turnaround times and another patient often waiting. Once the day’s list is finished, the approach shifts. This is a full infection control clean, not a quick touch-up.
Every accessible part of the room is addressed, from the ceiling-mounted operating lights above the table to the theatre floor below. Furniture is moved where practical rather than cleaned around, and equipment is wiped across all external surfaces, not just the controls touched during a procedure.
This is also where the distinction between high-touch and low-touch surfaces becomes important. Bed rails, trolley handles and door handles are cleaned every time because they carry a greater risk of transferring contamination. Ceiling fixtures, the underside of benches and other low-touch areas are handled less often, but they can still collect dust and residue over time.
A comprehensive clean reaches the areas that a quick between-case wipe-down doesn’t have time to cover.
Preparation and the right cleaning products
Preparation is the foundation of an effective theatre clean. Our cleaning teams begin by performing hand hygiene, donning the appropriate personal protective equipment and preparing fresh, colour-coded cleaning equipment dedicated to theatre environments. Using clean equipment throughout the process is essential to prevent cross-contamination between areas.
Selecting the appropriate cleaning chemicals is just as important. Commercial cleaning often relies on general-purpose detergents and disinfectants designed to remove dirt and improve appearance.
Hospital environments require Therapeutic Goods Administration (TGA) approved hospital-grade disinfectants that have been validated to kill specific microorganisms encountered in healthcare facilities. In some circumstances, specialised sporicidal disinfectants are required to manage organisms that standard disinfectants cannot effectively eliminate. These products must be prepared, applied and left on surfaces for precise contact times as specified in the manufacturer’s instructions to achieve the required level of disinfection.
The cleaning technique and sequence
Technique is equally important. Theatre cleaning follows a structured approach, beginning with the cleanest areas and progressing towards dirtier areas while working from high surfaces to low surfaces. Cleaning teams move methodically around the room and towards the exit to avoid recontamination of cleaned surfaces.
Every high-touch surface receives careful attention. Operating tables, surgical lights, anaesthetic machines, Mayo stands, instrument trolleys, computer workstations, monitors, door handles, storage cupboards, wall-mounted equipment, switches and benches are all cleaned and disinfected thoroughly. Even surfaces that appear clean can harbour microorganisms, which is why consistency and attention to detail matter throughout the process.
Scrub bays, anaesthetic rooms and the theatre floor
Scrub bays form part of the theatre cleaning routine, with sinks, taps, splashbacks, soap dispensers, hand dryers and nearby benches all cleaned and disinfected. Soap scum, mineral build-up and pooled water are also removed to help prevent bacteria from settling in.
Anaesthetic rooms are treated with the same care. Monitoring equipment, patient trolleys, preparation benches and the outside of anaesthetic workstations are cleaned using products suited to both the clinical setting and the equipment.
The floor comes last. Instead of dry sweeping which can send dust and microorganisms back into the air, damp mopping captures contaminants while keeping the environment controlled.
The final checks
Once cleaning is complete, the theatre is inspected to confirm every task meets the relevant health authorities’ guidelines. Cleaning records are completed to demonstrate compliance, chemicals and equipment are safely stored and any issues are identified before the operating suite is prepared for the next surgical list.
Although theatre cleaning often happens after the day’s clinical activity has ended, its impact continues well beyond the shift. Every properly disinfected surface helps break the chain of infection, minimise the risk of an outbreak and protect patients, surgeons, nurses and anaesthetic teams.
PPE: a stricter standard
Our cleaning franchisees wear the appropriate PPE when carrying out theatre cleans. This includes gloves, masks, hair nets, scrubs, eye protection and shoe covers, with shoe covers particularly required when attending to a theatre area while it is active during the day or during an emergency procedure late at night.
Compared to regular commercial cleaning, which typically only requires basic PPE such as gloves, theatre cleaning demands this additional layer of protection to meet stricter infection control standards. It is a visible reminder that the environment itself sets the rules, not the other way around.
A cleaning standard built for healthcare facilities
While many industries value cleanliness, healthcare demands something more. Hospital theatre cleaning is a highly specialised discipline where science, precision and consistency work together to act as the final safeguard before the next patient enters the operating theatre. Carried out using the correct chemicals, proven techniques and in accordance with HICMR guidelines, it becomes one of the most effective defenses to protect patients during some of the most vulnerable moments of their lives.
Theatre cleaning requires more than a general commercial cleaning approach. Jani-King’s franchisees are trained specifically for healthcare and medical environments, and have been supporting hospitals and clinics across Australia for over 30 years.
