Why Pharmaceutical Facilities Need Specialist Cleaning
Ireland is one of the world's leading pharmaceutical manufacturing centres, with over 120 pharmaceutical and biopharmaceutical companies operating in the country, producing approximately 50% of all medicines sold in Europe. These facilities operate under the most stringent cleaning and hygiene standards of any industry — because the consequences of contamination are not commercial inconvenience but direct patient harm.
The Health Products Regulatory Authority (HPRA) inspects pharmaceutical manufacturing facilities in Ireland against EU GMP (Good Manufacturing Practice) standards. A GMP deficiency finding related to cleaning can result in production suspension, batch recall, regulatory warning letters, and in severe cases, facility closure. Cleaning in a pharmaceutical facility is not housekeeping — it is a validated, documented, audited manufacturing support process that directly impacts product quality and patient safety.
Optus Glean provides dedicated pharmaceutical cleaning teams trained in GMP, cleanroom protocols, and the specific requirements of Ireland's pharmaceutical sector. Our operatives understand contamination control, aseptic technique, environmental monitoring, and the documentation standards required by HPRA. We work with pharmaceutical manufacturers, contract manufacturing organisations (CMOs), biotech companies, and medical device manufacturers across Ireland.
Cleanroom Cleaning (ISO 14644)
Cleanroom cleaning is the most technically demanding cleaning discipline. Every action inside a cleanroom — every movement, every wipe, every step — must be performed in a way that minimises particle generation and maintains the classified environment. Our cleanroom cleaning protocols are designed for ISO 14644-1 classified environments from ISO Class 5 (EU GMP Grade A) through ISO Class 8 (EU GMP Grade D).
- Floor cleaning using pre-saturated sterile mops (single-use for Grade A/B, validated re-use for Grade C/D)
- Wall cleaning using sterile wipes applied in overlapping unidirectional strokes
- Ceiling and light fitting cleaning including HEPA filter surrounds
- Equipment exterior cleaning using validated cleaning agents
- Pass-through hatch cleaning and sanitisation
- Airlock cleaning with door interlocking awareness
- Environmental monitoring support: settle plate placement, air sampling co-ordination
- Sporicidal rotation programme to prevent microbial adaptation
All cleanroom cleaning is performed using pre-validated methods with approved cleaning agents. Chemicals are rotated on a defined schedule (typically biocide and sporicide in rotation) to prevent microbial adaptation. All cleaning activities are recorded in batch-style documentation for GMP compliance.
Gowning Areas and Controlled Corridors
Gowning areas are the gateway between the uncontrolled and controlled environments. They are one of the most important areas in any pharmaceutical facility, and their cleanliness directly impacts the cleanliness of the cleanrooms they serve. Our gowning area cleaning covers floor cleaning and sanitisation, bench and seating cleaning, gowning hooks and storage cleaning, mirror and vision panel cleaning, air shower maintenance (external surfaces only — HVAC systems maintained by engineering), waste bin emptying and liner replacement, and hand sanitiser dispenser refilling. Gowning areas are cleaned daily, with a deep clean weekly. Cleaning moves from the clean side (closest to the cleanroom) to the dirty side (closest to the corridor) to maintain the contamination gradient.
Non-Classified and Support Area Cleaning
Pharmaceutical facilities include extensive non-classified areas — warehouses, packaging halls, QC laboratories, offices, canteens, and staff facilities — that still require higher-than-standard cleaning to support the overall contamination control strategy. These areas are cleaned to defined standards that prevent them from becoming contamination sources for the classified areas.
Our support area cleaning includes office and laboratory cleaning, warehouse and staging area floor care, packaging hall cleaning with particulate control, washroom and changing room cleaning, canteen and break room HACCP-compliant cleaning, loading dock and goods-in area cleaning, and waste management including pharmaceutical waste segregation. All support area cleaning is documented and scheduled in co-ordination with cleanroom cleaning to maintain the facility's contamination control hierarchy.
Pharmaceutical Cleaning Pricing
Pharmaceutical cleaning pricing depends on the ISO classification of cleanrooms, the size of the facility, validation requirements, and the scope of controlled environments. Below are indicative 2026 pricing ranges for Ireland.

| Shutdown deep clean | €5,000 – €25,000+ | Full facility, validated, documented |
| Cleaning validation support | €1,500 – €5,000 | Protocol development + execution |
Note: Prices exclusive of VAT. All pricing includes GMP-compliant documentation, validated cleaning agents, cleanroom-trained operatives, and environmental monitoring support. Pricing is based on individual site survey and validation requirements.
Cleaning Validation and Documentation
In pharmaceutical manufacturing, cleaning validation is a regulatory requirement. Every cleaning method must be proven effective through documented validation, and the validated state must be maintained through ongoing monitoring and change control. Optus Glean supports your cleaning validation programme by developing cleaning SOPs for every area and equipment type, executing validation protocols under QA oversight, providing environmental monitoring data (particle counts, microbial monitoring), maintaining batch-style cleaning records for each cleaning event, participating in deviation investigation and CAPA processes, and managing change control for any modification to cleaning methods. Our documentation system is designed to withstand HPRA inspection and meets the requirements of EudraLex Volume 4, PIC/S guidance, and FDA expectations for facilities exporting to the United States.

Frequently Asked Questions About Pharmaceutical Cleaning
How much does pharmaceutical cleaning cost in Ireland?
Pharmaceutical cleaning costs between €2,000 and €8,000+ per month in 2026. A small packaging facility is €2,000–€3,500/month. A mid-sized manufacturing facility is €3,500–€5,500/month. A large multi-building campus is €5,500–€8,000+/month. All pricing includes GMP documentation and cleanroom-trained staff.
What ISO cleanroom classifications can you clean?
We clean ISO Class 5 (Grade A) through ISO Class 8 (Grade D). Each classification has specific requirements — from HEPA-filtered vacuums for ISO 7-8 to pre-sterilised equipment and full aseptic gowning for ISO 5-6. Methods are validated as part of your cleanroom qualification programme.
How do you validate pharmaceutical cleaning?
We develop written SOPs, define acceptance criteria, use validated cleaning agents, perform environmental monitoring, conduct swab and rinse sampling, maintain training records, and follow change control procedures. All documentation is GMP-compliant for HPRA inspection.
What gowning protocols do your cleaners follow?
Our operatives follow the same gowning protocols as production staff, appropriate to each ISO class. This ranges from basic hair cover and overshoes for Grade D, to full sterile coverall, hood, mask, goggles, double gloves, and boots for Grade A/B. Operatives are trained and assessed in aseptic gowning technique.
Do you comply with HPRA and GMP requirements?
Yes. We comply with HPRA requirements, EU GMP (EudraLex Volume 4), Annex 1, ISO 14644, and PIC/S guidance. We maintain audit-ready documentation including SOPs, batch records, environmental data, training records, and deviation/CAPA records.
Can you clean during production or only during shutdowns?
We provide both operational cleaning during production (corridors, gowning areas, airlocks, between-batch cleanroom cleaning) and comprehensive shutdown cleaning. Schedules are co-ordinated with your production planning team to maximise uptime while maintaining GMP compliance.
