Airport Cleaning Services Across Ireland
Ireland's airports handle over 40 million passengers annually. Dublin Airport alone processed 33.7 million passengers in 2024, with Cork, Shannon, Ireland West Airport Knock, Kerry, and Donegal airports serving millions more. Every one of those passengers forms an impression of Ireland the moment they step into the terminal building. The cleanliness of the terminal concourse, the washrooms, the gate lounges, the retail areas, and the arrivals hall is one of the first and last things any traveller notices.
Optus Glean provides airport and transport hub cleaning services to airports, bus depots, train stations, and Luas stops across Ireland. We operate 24 hours a day, 7 days a week, 365 days a year, because airports and transport hubs never close. Our cleaning teams are Garda vetted, security cleared for airside operations where required, Safe Pass certified, and trained in aviation-specific cleaning protocols.
We serve both facilities management companies who subcontract specialist cleaning and airport authorities who procure cleaning services directly. Whether you need a team of 50 operatives cleaning a terminal building around the clock or a specialist deep cleaning crew for a bus depot, Optus Glean has the scale, the systems, and the compliance documentation to deliver.
Airside vs Landside Cleaning: Understanding the Difference
Airport cleaning is divided into two distinct operational zones, each with different security requirements, access protocols, and cleaning challenges.
Airside Cleaning
Airside areas are located beyond the security screening checkpoint. Access requires an airside identity card (AIC) issued by the airport authority under the National Civil Aviation Security Programme (NCASP). All cleaning operatives working airside must undergo enhanced security vetting, including fingerprinting, background checks, and security awareness training. The vetting process typically takes 4 to 8 weeks.
Airside cleaning covers:
- Departure lounges and gate seating areas
- Airside retail units, restaurants, and food courts
- Airside washrooms and baby changing facilities
- Air bridges and jet bridges
- Airline lounges and VIP areas
- Duty-free shopping areas
- Boarding card check areas and security screening halls
Airside cleaning requires strict adherence to security protocols. Cleaning equipment and chemicals must be approved for airside use. Staff must wear visible identification at all times. Cleaning schedules must be coordinated with flight operations and security sweeps.
Landside Cleaning
Landside areas include everything before the security checkpoint and all public-facing areas of the airport. Cleaning operatives require standard Garda vetting but do not need airside security clearance.
Landside cleaning covers:
- Check-in halls and airline ticket desks
- Arrivals halls and baggage reclaim areas
- Public concourses and information desks
- Landside retail units and food outlets
- Public washrooms
- Car park stairwells, lifts, and walkways
- External forecourts, drop-off zones, and taxi ranks
- Bus and coach stops connected to the terminal
Bus Depot and Train Station Cleaning
Airport cleaning is only one part of Optus Glean's transport hub capability. We provide the same level of professional, documented, compliant cleaning to bus depots, train stations, tram stops, and coach terminals across Ireland.
Bus Depot Cleaning
Ireland's bus network operates through Dublin Bus, Bus Eireann, Go-Ahead Ireland, and numerous private operators. Bus depots require specialist cleaning that goes beyond standard commercial cleaning. Optus Glean provides:
- Depot building cleaning: offices, canteens, driver rest areas, washrooms
- Workshop and maintenance bay degreasing and deep cleaning
- Bus wash systems maintenance and pit lane cleaning
- Passenger waiting areas and bus shelters
- Fleet interior cleaning: seats, grab poles, floors, windows, and driver cabs
- Terminal building cleaning for bus stations such as Busaras and regional terminals
Train Station and Luas Stop Cleaning
Irish Rail operates over 145 stations across the national rail network. The Luas tram system in Dublin has 67 stops across two lines. Optus Glean provides cleaning services for:
- Station concourses, ticket halls, and platform areas
- Platform edge cleaning and track-side litter collection
- Station washrooms and staff facilities
- Waiting rooms and passenger shelters
- Lift and escalator cleaning
- Station car parks and bicycle storage areas
- Tram stop cleaning including platform, shelter, and ticket machine areas
24/7 Operations and Shift Patterns
Airports and major transport hubs operate around the clock. Cleaning operations must be continuous, with different intensity levels throughout the day to match passenger flow patterns. Optus Glean structures airport cleaning operations in three primary shift patterns:
- Day shift (06:00–14:00) — Peak passenger periods require continuous cleaning of washrooms, concourses, gate areas, and food courts. Reactive cleaning teams respond to spills, litter, and incidents in real time.
- Evening shift (14:00–22:00) — Continued reactive cleaning during the afternoon and evening passenger peaks, plus scheduled deep cleaning of areas that clear as evening flights depart.
- Night shift (22:00–06:00) — The deep cleaning window. With reduced passenger numbers, night teams carry out intensive floor care, machine scrubbing, high-level dusting, window cleaning, and washroom deep cleans to reset the terminal for the morning rush.
All shifts are managed through a site supervisor who reports to an Optus Glean operations manager. Digital quality audits are conducted at each shift change, and deficiency reports are actioned immediately.
Transit Cleaning: Speed and Consistency
Transit cleaning is the rapid turnaround cleaning performed between uses of a vehicle, carriage, or space. In the transport sector, transit cleaning must be fast, thorough, and consistent across hundreds of daily operations.
Aircraft Transit Cleaning
When an aircraft lands and passengers disembark, the cleaning crew has a narrow window — typically 20 to 45 minutes — to prepare the cabin for the next flight. Aircraft transit cleaning includes:
- Collecting all litter and removing items from seat pockets
- Wiping tray tables, armrests, and seatbelt buckles
- Vacuuming all carpet areas and spot-cleaning stains
- Cleaning and restocking lavatories
- Wiping overhead bin handles and window surrounds
- Replacing headrest covers where required
Bus and Train Transit Cleaning
At terminus points, buses and trains undergo a similar rapid clean. Dublin Bus alone operates over 1,000 vehicles, each requiring cleaning at least once per rotation. Transit cleaning for ground transport includes seat wiping, floor sweeping, litter collection, grab pole sanitisation, driver cab cleaning, and washroom restocking on intercity coaches.
Security Vetting and Compliance
Airport cleaning demands the highest level of security compliance. Every Optus Glean operative assigned to airport or transport hub contracts undergoes:
- Garda vetting through the National Vetting Bureau (mandatory for all staff)
- Enhanced security clearance for airside operations (AIC application via airport authority)
- Security awareness training compliant with the National Civil Aviation Security Programme
- Safe Pass certification for any construction or maintenance-adjacent areas
- Manual handling training for equipment operation and waste removal
- COSHH training for cleaning chemical handling in confined and public spaces
We maintain a live register of all security clearances, training certifications, and vetting status for every operative. Expiry dates are tracked automatically, and renewals are processed well in advance to ensure zero gaps in compliance.
Equipment and Methodology
Airport and transport hub cleaning requires specialist equipment that can operate effectively in large, high-traffic environments without disrupting passenger flow. Optus Glean deploys:
- Ride-on scrubber dryers — For rapid floor cleaning across large terminal concourses. These machines clean, scrub, and dry in a single pass, allowing passengers to walk on the floor immediately.
- Battery-powered vacuum cleaners — Cordless operation eliminates trip hazards in public areas and allows cleaning without access to power outlets.
- Microfibre cleaning systems — Colour-coded microfibre cloths and mops reduce chemical usage by up to 80% and prevent cross-contamination between zones.
- Escalator and travelator cleaning machines — Specialist equipment designed to deep clean escalator treads and travelator belts.
- High-level access equipment — Cherry pickers, scissor lifts, and water-fed pole systems for cleaning terminal glass facades, high-level signage, and roof structures.
- Pressure washing equipment — For external forecourts, taxi ranks, drop-off zones, and car park structures. See our pressure washing services for more detail.
Tendering for Airport Cleaning Contracts
Airport cleaning contracts in Ireland are procured through formal tender processes. Understanding the procurement landscape is essential for any cleaning company seeking to enter the aviation sector.
The principal airport authorities in Ireland are:
- DAA (Dublin Airport Authority) — Operates Dublin Airport and Cork Airport. Procurement is managed through DAA's commercial department and published on eTenders.gov.ie.

Frequently Asked Questions About Airport Cleaning
Who cleans Dublin Airport?
Dublin Airport is cleaned by a combination of contracted facilities management companies and specialist cleaning providers. DAA (the airport authority) tenders cleaning contracts on a multi-year basis. Large FM companies such as Bidvest Noonan and OCS have historically held contracts at Dublin Airport. Specialist cleaning companies like Optus Glean provide subcontracted or direct cleaning services for terminal areas, retail units within the airport, and transport connections.
What does airport cleaning involve?
Airport cleaning involves maintaining all public areas to the highest hygiene and presentation standards around the clock. This includes terminal concourse cleaning, washroom deep cleaning and restocking, gate lounge cleaning between flights, retail unit cleaning, food court sanitisation, baggage hall and arrivals area cleaning, external forecourt and drop-off zone cleaning, and specialist tasks such as escalator cleaning, travelator maintenance, and high-level glass cleaning.
What companies do airport cleaning?
Airport cleaning in Ireland is carried out by specialist facilities management and cleaning companies. Major providers include Bidvest Noonan, OCS, ABM, and ISS. Regional and specialist cleaning companies like Optus Glean also service airports and transport hubs, either through direct contracts or as subcontractors to principal FM providers. Successful airport cleaning companies must demonstrate security vetting capability, 24/7 operational capacity, and compliance with aviation security regulations.
How do you get a cleaning contract at an airport?
Airport cleaning contracts are typically awarded through formal tender processes managed by the airport authority. DAA manages procurement for Dublin and Cork airports, with tenders published on eTenders.gov.ie. To qualify, cleaning companies must demonstrate adequate insurance cover (typically €6.5M+ public liability), security vetting capability, 24/7 staffing capacity, relevant experience in high-footfall environments, and compliance with aviation security requirements. Optus Glean maintains all required documentation and is tender-ready for airport procurement processes.
What is airside vs landside cleaning?
Airside cleaning takes place beyond the security checkpoint and includes departure lounges, gate areas, air bridges, and apron-level facilities. All airside staff require enhanced security clearance (airside identity cards) issued by the airport authority. Landside cleaning covers areas before security, including check-in halls, arrivals areas, public concourses, car parks, and external forecourts. Landside staff require standard Garda vetting but not airside security clearance. Both zones require different operational protocols and staffing arrangements.
Do airport cleaners need security clearance in Ireland?
Yes. All airport cleaning staff in Ireland require Garda vetting as a minimum. Staff working in airside areas require additional security clearance in the form of an airside identity card (AIC) issued by the airport authority under the National Civil Aviation Security Programme. This involves enhanced background checks, fingerprinting, and security awareness training. The process typically takes 4 to 8 weeks. Optus Glean manages the full vetting and clearance process for all airport-assigned staff.
How do you bid for airport cleaning contracts?
Airport cleaning contracts in Ireland are procured through public tender processes published on eTenders.gov.ie and through airport authority procurement portals. Bids must include detailed method statements, staffing plans, equipment lists, insurance documentation, health and safety policies, quality management systems, and pricing schedules. Pre-qualification questionnaires are common. You must demonstrate relevant experience, financial stability, and insurance cover meeting airport authority thresholds.
What is transit cleaning?
Transit cleaning is the rapid turnaround cleaning performed between passenger use of a vehicle or space. In airports, it means cleaning an aircraft cabin in 20 to 45 minutes between flights. In bus and rail operations, it is the quick clean at terminus points between routes. Transit cleaning includes litter collection, seat wiping, floor sweeping, washroom restocking, and sanitisation of high-touch surfaces such as grab poles, armrests, and tray tables.
