Precision cleaning for controlled spaces
Cleanrooms in pharmaceutical, biotech, medical device, electronics and laboratory facilities are classified for particle counts, often to ISO 14644 standards, and many also have microbial limits. Cleaning these spaces is about technique as much as chemistry: the right garments, low-linting wipes and mops, a defined sequence from clean to less clean and top to bottom, validated disinfectants and sporicides, and careful documentation.
When outside help makes sense
- Recovery cleaning after a shutdown, construction, maintenance or a contamination event
- Start-up cleaning of new or renovated controlled spaces before certification
- Excursion response when monitoring shows particle or microbial counts out of limits
- Supplemental staffing for periodic deep cleaning
How the work is done
- Review your procedures. We work to your written cleaning procedures, approved agents, rotation schedule and gowning requirements.
- Gown and enter according to your entry procedures.
- Clean in sequence, ceilings, walls, fixtures, equipment exteriors and floors, using your specified tools and overlapping strokes.
- Apply disinfectants and sporicides with required contact times, followed by residue removal where specified.
- Document each room, agent, lot number and step on your logs or ours.
Construction and start-up
New cleanrooms and renovated spaces need multiple cleaning passes before they reach certification levels. We coordinate passes with contractors and your certifier.
What we don't do
Certification testing (particle counts, airflow and filter testing) is performed by independent certifiers. We prepare rooms for certification and work with your certifier's schedule.
Common questions
Can you follow our SOPs exactly?
Yes. In controlled environments, your procedures govern the work.
Do you have cleanroom-trained staff?
We assign field partners with experience in controlled environment cleaning and confirm training requirements with you before the project.
Do you clean biosafety labs?
Laboratory decontamination depends on the agents involved and your biosafety officer's requirements. Contact us to discuss.
