Why Hospital Cleaning Is Different from Commercial Cleaning
Hospital cleaning is not commercial cleaning with a different label. It is a specialist clinical discipline that sits at the intersection of infection prevention and control (IPC), patient safety, and environmental hygiene. In a hospital, the consequences of inadequate cleaning are measured not in complaints or aesthetics, but in healthcare-associated infections (HCAIs), patient morbidity, extended hospital stays, and — in the worst cases — preventable deaths.
Ireland's hospitals face persistent challenges with HCAIs. The HSE's Health Protection Surveillance Centre (HPSC) monitors rates of MRSA, C. difficile, CPE (carbapenemase-producing Enterobacterales), and other multi-drug resistant organisms across the acute hospital network. Environmental cleaning is a front-line defence against the transmission of these organisms. A contaminated bed rail, an inadequately cleaned commode, or a poorly decontaminated operating theatre surface can become the vector through which a life-threatening infection passes from one patient to another.
This is why hospital cleaning demands a fundamentally different approach: defined risk zones, colour-coded equipment, healthcare-grade chemicals, trained and competent operatives, documented schedules, auditable outcomes, and oversight by infection control teams. Optus Glean provides this level of specialist hospital cleaning across Ireland — from community hospitals and day hospitals to large acute teaching hospitals with operating theatres, intensive care units, and emergency departments.
Ward Cleaning Services
Hospital wards are where patients spend the majority of their stay. Ward environments range from low-acuity step-down beds to high-dependency units where patients are critically ill and immunocompromised. Our ward cleaning programme is tailored to the risk profile of each ward.
General Ward Cleaning
General medical and surgical wards receive daily cleaning that covers patient bed spaces (bed frame, rails, overbed table, locker, chair, call bell), high-touch surfaces throughout the ward (door handles, light switches, handrails, nurse station surfaces), ward bathrooms and en-suite facilities, dayrooms and patient lounges, ward kitchens, corridors and circulation areas, sluice rooms, and storage areas. Cleaning is performed using the colour-coded cleaning system with blue equipment for general ward areas, red for sanitary areas, and yellow for clinical zones.
Isolation Room Cleaning
Patients with confirmed or suspected infections — MRSA, C. difficile, CPE, norovirus, influenza, COVID-19, tuberculosis — are nursed in isolation rooms or cohort bays. Cleaning these areas requires enhanced precautions: dedicated yellow-coded equipment used exclusively in the isolation zone, full PPE (apron, gloves, mask, eye protection as directed by IPC team), sporicidal disinfectants for C. difficile and norovirus, enhanced high-touch surface cleaning frequency (minimum twice daily), terminal cleaning after patient discharge including curtain change, mattress decontamination, and full environmental wipe-down, and documented cleaning with sign-off by the ward manager or IPC nurse.
ICU and HDU Cleaning
Intensive Care Units (ICU) and High Dependency Units (HDU) are the highest-risk environments in any hospital. Patients are mechanically ventilated, have multiple invasive devices, and are profoundly immunocompromised. Environmental cleaning in ICU/HDU is performed to the most stringent standards: every bed space cleaned a minimum of twice daily with detergent-disinfectant, all monitoring equipment surfaces cleaned between patients, ventilator external surfaces cleaned daily, ICU bathrooms cleaned three times daily, and weekly deep clean of the entire unit including ceiling tiles, light fittings, ventilation grilles, and storage areas. Our ICU cleaning operatives receive specialist training and work in close coordination with the critical care nursing team.
Operating Theatre Cleaning
Operating theatres are classified as ultra-clean environments. The cleaning of theatre suites is arguably the most demanding and regulated aspect of hospital cleaning. Optus Glean provides three categories of theatre cleaning, each with distinct protocols.
Between-Case Cleaning
Between surgical cases, the theatre must be cleaned rapidly and thoroughly to prepare for the next patient. Between-case cleaning includes wiping all horizontal surfaces with detergent-disinfectant, cleaning the operating table and all attachments, mopping the theatre floor with particular attention to the area under and around the operating table, cleaning anaesthetic equipment surfaces, removing and replacing waste bags and sharps containers if full, and checking and restocking hand hygiene stations. Between-case cleaning is completed within a defined turnaround time — typically 15 to 20 minutes — to maintain theatre efficiency without compromising cleanliness standards.
Terminal Theatre Cleaning
At the end of each operating list (or after an infected case), a terminal clean is performed. This is a comprehensive decontamination of the entire theatre environment: all surfaces cleaned from ceiling to floor using a systematic approach, theatre lights and satellite equipment cleaned, anaesthetic machine and trolley surfaces decontaminated, walls spot-cleaned and splashback areas fully cleaned, floor scrubbed with hospital-grade disinfectant, all mobile equipment moved and cleaned underneath, ventilation grilles and diffusers checked and cleaned, and clean equipment re-stocked. Terminal cleaning after an infected case (e.g., a patient with CPE or MRSA) includes enhanced disinfection protocols specified by the hospital's IPC team.
Periodic Deep Clean
In addition to daily between-case and terminal cleaning, operating theatres require periodic deep cleans. These are scheduled monthly or quarterly depending on theatre usage and are comprehensive: ceiling tiles removed and cleaned or replaced, walls washed from ceiling to floor, all fixed equipment moved and cleaned behind, floor stripped (if applicable), cleaned, and re-sealed, storage cupboards emptied, cleaned inside and out, and restocked, light fittings and pendants dismantled and cleaned, and air handling unit grilles cleaned. Deep cleans are typically scheduled at weekends or during theatre downtime to minimise disruption to surgical lists.
A&E and Emergency Department Cleaning
Emergency departments (A&E) are among the most challenging hospital environments to keep clean. They operate 24 hours a day, 7 days a week, with unpredictable patient volumes, high-acuity presentations, and constant foot traffic from patients, ambulance crews, Gardaí, and visitors.
Our A&E cleaning programme addresses these challenges with continuous cleaning presence during peak hours (typically 10:00–02:00), rapid response to blood and body fluid spillages (target response: under 10 minutes), regular trolley and cubicle wipe-down between patients, waiting room and triage area cleaning throughout the day, resuscitation room terminal cleaning after each use, ambulance bay and entrance cleaning, and mental health assessment room cleaning with attention to ligature-risk furniture. A&E cleaning staff must be comfortable working in a fast-paced, high-pressure environment alongside paramedics, emergency physicians, and often distressed patients and families. Our A&E operatives are selected for temperament as well as technical competence.
Outpatient and Day-Case Unit Cleaning
Outpatient departments and day-case units see high volumes of patients attending for consultations, procedures, and treatments before returning home the same day. These areas require daily cleaning that focuses on waiting areas and reception desks, consultation rooms (cleaned between clinics), treatment and procedure rooms, changing areas, patient toilets and accessible facilities, and corridor and circulation areas.
Day-case units where minor surgical procedures and endoscopy are performed require theatre-adjacent cleaning standards, with between-procedure cleaning and terminal cleaning at the end of each list. Our outpatient cleaning schedules are built around clinic timetables to ensure cleaning is completed before the first patient arrives each morning and between clinic sessions throughout the day.
Maternity Unit Cleaning
Maternity units present unique cleaning requirements. New mothers and newborn babies are particularly vulnerable to infection, and the emotional significance of the environment demands exceptional standards of cleanliness and presentation.
Our maternity unit cleaning covers labour and delivery rooms (terminal cleaned after each birth), postnatal wards and individual rooms, the Special Care Baby Unit (SCBU) and Neonatal Intensive Care Unit (NICU), antenatal clinics and assessment units, maternity theatre suites, breastfeeding rooms and parent facilities, and maternity kitchen and formula preparation areas. SCBU and NICU cleaning is performed to ICU-equivalent standards, with particular attention to incubator surrounds, monitoring equipment surfaces, and hand hygiene station maintenance. Maternity kitchen and formula preparation areas are cleaned to food-safety standards with green-coded equipment.
Mental Health Facility Cleaning
Mental health inpatient units — whether within general hospitals or standalone approved centres — have specific cleaning considerations that go beyond standard ward cleaning. Patient safety is paramount: cleaning products must be stored securely and never left unattended, equipment must not include items that could be used for self-harm (e.g., long cords, aerosol cans), and cleaning schedules must accommodate patients who may be agitated, confused, or distressed.
Our mental health facility cleaning programme includes anti-ligature awareness training for all operatives, secure chemical storage and inventory management, patient-sensitive cleaning (operatives trained to maintain a calm, non-threatening presence), enhanced cleaning of seclusion and de-escalation rooms, and compliance with Mental Health Commission standards for approved centres. We work closely with mental health nursing teams to understand the specific needs of each unit and adjust our approach accordingly.
The Colour-Coded Cleaning System Explained
The colour-coded cleaning system is the cornerstone of infection prevention in hospital cleaning. It prevents cross-contamination by ensuring that cleaning equipment used in one type of area is never used in another. The system is mandated by the HSE National Cleaning Standards Manual and is a key inspection point for HIQA audits.
| Colour | Area | Equipment | Risk Level |
|---|---|---|---|
| Red | Washrooms, toilets, sanitary areas, sluice rooms | Red mops, red cloths, red buckets, red spray bottles | Very High |
| Yellow | Clinical areas, isolation rooms, treatment rooms, procedure rooms | Yellow mops, yellow cloths, yellow buckets, yellow spray bottles | Very High |
| Green | Kitchens, food service areas, ward kitchens, canteens | Green mops, green cloths, green buckets, green spray bottles | High |
| Blue | General areas: corridors, offices, waiting rooms, staff rooms, lobbies | Blue mops, blue cloths, blue buckets, blue spray bottles | Low – Significant |
Every Optus Glean operative working in a hospital environment is trained in colour-coded cleaning and assessed for competency before deployment. Equipment is checked and replaced regularly, and colour integrity is maintained through a documented inventory system.
Cleaning Frequency by Hospital Risk Zone
The HSE National Cleaning Standards Manual defines cleaning frequencies based on the risk classification of each hospital area. Optus Glean builds cleaning schedules that meet or exceed these minimum frequencies.
| Risk Category | Example Areas | Routine Cleaning | Deep Clean |
|---|---|---|---|
| Very High Risk | Operating theatres, ICU, HDU, SCBU/NICU, isolation rooms, burns units | 2–3 times daily | Weekly |
| High Risk | General wards, A&E, maternity, renal dialysis, endoscopy, pharmacy | Daily (minimum) | Monthly |
| Significant Risk | Outpatient clinics, day-case units, physiotherapy, radiology, pathology | Daily | Quarterly |
| Low Risk | Offices, meeting rooms, corridors, reception, staff rooms, stores | Daily or 3–5 times/week | 6-monthly |
HSE National Cleaning Standards Manual Compliance
The HSE National Cleaning Standards Manual is the definitive reference document for hospital cleaning in Ireland. It sets out the standards, frequencies, methods, and audit frameworks that every hospital cleaning service must follow. Optus Glean's hospital cleaning programmes are built directly from this manual.
Key elements of our HSE compliance programme include area risk classification aligned with the Manual's four-tier risk model, cleaning schedules that meet or exceed the minimum frequencies for each risk category, chemical selection from the Manual's approved product types, colour-coded cleaning system as specified in the Manual, documented cleaning records with operative sign-off, cleaning audit programme using the Manual's 49-element audit tool, corrective action procedures for audit findings below the compliance threshold (85% for high-risk areas, 75% for low-risk), management reporting with trend analysis and action planning, and annual review and update of cleaning specifications to reflect Manual revisions.
Compliance with the HSE National Cleaning Standards Manual is not optional — it is the baseline expectation for any hospital cleaning provider in Ireland. Our programme is designed to consistently exceed the Manual's minimum standards and to demonstrate this through documented, auditable evidence.
HIQA Inspection Preparation
HIQA (the Health Information and Quality Authority) conducts inspections of public and private hospitals in Ireland. Environmental cleanliness is a core component of HIQA’s assessment framework, sitting within the broader themes of patient safety and quality of care. A HIQA inspection can be announced or unannounced, and inspectors will assess the cleanliness of patient areas, clinical areas, public areas, and support areas.
Optus Glean supports hospitals in HIQA inspection preparation by maintaining inspection-ready cleaning standards at all times (not just before inspections), providing a complete documentation suite ready for inspector review, conducting regular internal cleaning audits that mirror HIQA’s assessment methodology, training operatives to answer inspector questions about their cleaning procedures, ensuring all IPC training is current and documented, maintaining up-to-date chemical safety information and COSHH records, and providing rapid-response deep cleaning for any areas identified as concerns before or during an inspection.
Our philosophy is simple: if your hospital is always clean to HIQA standard, HIQA inspections become a confirmation exercise rather than a cause for anxiety. We help hospitals achieve and maintain that standard every day, not just on inspection day.
Staff Training Requirements
Hospital cleaning operatives are not general cleaners with an upgraded title. They are specialist environmental hygiene professionals who require extensive and ongoing training to work safely and effectively in a clinical environment.

Frequently Asked Questions — Hospital Cleaning in Ireland
How much does hospital cleaning cost in Ireland?
Hospital cleaning in Ireland costs between €14 and €20 per hour for contract cleaning operatives, with theatre and 24/7 on-call cover at higher rates. Monthly contract costs range from €4,000–€8,000 for a small community hospital to €25,000–€60,000+ for a large acute hospital with theatres, ICU, and A&E. All pricing includes HSE-compliant documentation, IPC-trained operatives, colour-coded systems, and quality audits.
What training do hospital cleaners need?
Hospital cleaners require IPC training, hand hygiene (WHO 5 Moments), PPE donning and doffing, colour-coded cleaning system operation, chemical safety, sharps awareness, blood/body fluid spillage management, healthcare waste segregation, manual handling, fire safety, patient confidentiality, and safeguarding. Specialist areas (theatres, isolation, mental health, neonatal) require additional training modules. All training is documented and refreshed annually.
What is the colour-coded cleaning system?
The colour-coded system uses different coloured equipment for different hospital zones: red for washrooms and toilets, yellow for clinical and isolation areas, green for kitchens and food service areas, and blue for general low-risk areas. This prevents cross-contamination between zones. The system is mandated by the HSE National Cleaning Standards Manual and checked during HIQA inspections.
How often should hospital wards be deep cleaned?
Deep cleaning frequency depends on risk classification: very high risk areas (ICU, theatres, isolation) weekly; high risk areas (general wards, A&E, maternity) monthly; significant risk areas (outpatients, day-case) quarterly; and low risk areas (offices, corridors) every six months. Terminal cleaning is performed after every patient discharge from isolation rooms and after infection outbreaks.
Do you provide cleaning for Cavan General Hospital?
Yes. We are based in Co. Monaghan, close to Cavan General Hospital, and serve the full RCSI Hospital Group catchment area. We also provide hospital cleaning across all six HSE Hospital Groups and to private hospitals nationwide. Our proximity to Cavan means rapid mobilisation for emergency cleaning and outbreak response.
