Industrial Cleaning Across Limerick's Manufacturing Heartland
Limerick and the adjoining Shannon region form one of Ireland's most significant industrial corridors. The Raheen Industrial Estate south of the city is home to major pharmaceutical, medical device, and technology manufacturers. The National Technology Park at Castletroy/Plassey houses semiconductor manufacturing and technology companies. The Shannon Free Zone — Europe's first free trade zone — hosts over 170 companies across manufacturing, aviation maintenance, logistics, and technology. Combined, these clusters employ tens of thousands of people in environments that require specialist industrial cleaning far beyond standard commercial cleaning.
Optus Glean provides industrial cleaning services for manufacturing facilities, warehouses, laboratories, cleanrooms, production floors, and logistics centres across Limerick city, county, and the Shannon region. Our teams are Safe Pass certified, trained in industrial safety protocols, and experienced with multi-shift operations. We provide 24/7 cleaning coverage to match your production schedule.
Raheen Industrial Estate
Raheen Industrial Estate is one of Ireland's premier industrial locations. Regeneron Pharmaceuticals has invested over €1.8 billion in its Raheen campus, manufacturing biologic medicines in state-of-the-art facilities. Cook Medical manufactures minimally invasive medical devices. Analog Devices designs and manufactures semiconductors. These are demanding environments that require GMP-compliant cleaning, cleanroom maintenance, controlled-environment protocols, and the ability to work around 24/7 production without causing contamination or downtime. Optus Glean provides dedicated industrial cleaning teams for Raheen facilities, trained in pharmaceutical and medical device manufacturing cleaning standards.
Shannon Free Zone
The Shannon Free Zone hosts companies across aviation (including Shannon Engine Support and Lufthansa Technik), manufacturing, logistics, and technology. Aviation maintenance facilities require specialist cleaning including hangar floor cleaning, parts-washing area maintenance, and office cleaning within industrial buildings. Manufacturing and logistics operations need production floor scrubbing, warehouse cleaning, loading dock maintenance, and waste management. Our Shannon teams serve the entire free zone and the surrounding industrial areas.
Castletroy and the National Technology Park
While primarily known for technology offices, the Castletroy area also houses semiconductor manufacturing (Analog Devices), research laboratories (University of Limerick), and light manufacturing. These environments require clean-environment protocols, ESD-safe cleaning procedures, and laboratory cleaning expertise. Optus Glean provides industrial and specialist cleaning for the Castletroy technology cluster.
Food Sector and Agri-Industry
County Limerick has a significant food processing and dairy sector. HAACP-compliant cleaning for food production facilities requires specialist knowledge of food-safe chemicals, allergen cleaning protocols, and the hygiene standards mandated by the FSAI (Food Safety Authority of Ireland). We clean food processing plants, dairy facilities, cold storage units, and distribution centres across Limerick and the surrounding region.

Do you clean pharmaceutical facilities at Raheen Industrial Estate?
Yes. Raheen Industrial Estate is a core service area for Optus Glean. We provide GMP-compliant industrial cleaning for pharmaceutical and medical device manufacturing facilities including Regeneron, Cook Medical, and other companies at Raheen. Our pharmaceutical cleaning teams are trained in cleanroom protocols, gowning procedures, controlled-environment cleaning, production floor sanitisation, and the documentation requirements of GMP-regulated environments. We maintain full cleaning validation records for audit purposes.
Can you provide 24/7 industrial cleaning in Limerick?
Yes. Many of Limerick's manufacturing facilities operate continuous 24/7 production, particularly in the pharmaceutical and medical device sectors at Raheen and Castletroy. Our industrial cleaning teams work dedicated shift patterns — typically aligned with your production shifts — to ensure cleaning happens during changeovers, planned breaks, or alongside production without causing interruption. We can provide 3-shift coverage (mornings, afternoons, nights) or continuous presence as required by your facility.
Do you clean the Shannon Free Zone?
Yes. The Shannon Free Zone is within our Limerick/Shannon service area. We clean manufacturing facilities, aviation maintenance hangars, logistics warehouses, and office buildings across the zone. Shannon hosts over 170 companies, and we have experience with the diverse range of industrial environments found there, from precision engineering and aviation MRO to food processing and logistics. Our Shannon teams can also be deployed to Shannon Airport for airport cleaning requirements.
What industrial cleaning equipment do you use?
Our industrial cleaning fleet is tailored to each facility's requirements. Standard equipment includes ride-on scrubber-dryers for large floor areas, walk-behind scrubber-dryers for confined spaces, industrial vacuum cleaners with HEPA filtration for dust-sensitive environments, high-pressure washers for external and heavy-duty cleaning, steam cleaners for degreasing, specialist degreasing equipment for engineering environments, elevated work platforms for high-level cleaning, and cleanroom-grade mopping and wiping systems for pharmaceutical environments. All equipment is maintained, PAT tested, and calibrated.
Do your teams have Safe Pass and manual handling certification?
Yes. Every industrial cleaning operative holds current Safe Pass certification (mandatory for construction and industrial sites in Ireland), manual handling training, chemical safety training (COSHH equivalent), and site-specific induction. For pharmaceutical facilities, our teams also complete GMP awareness training, clean-area behaviour training, and gowning qualification. For food facilities, we provide HACCP awareness training. We maintain comprehensive training records and can provide these for any audit or compliance check.
