Cleanroom cleaning and controlled environments
Cleaning that belongs inside your contamination-control plan: gowned crews trained to your procedure, your approved chemistries on your rotation, and a record for every room and every lot.
What we look for
On the walk, in the suite.
The notes we write at the gowning room door before anyone cleans anything.
- Classification
The posted class of each room, and which rooms share an airlock. Cleaning order follows the pressure cascade, cleanest first.
- Gowning
The gown-in sequence as posted, the garment supply, where the tacky mats sit and who changes them.
- Surfaces
Walls, ceilings, floors, equipment exteriors, pass-throughs. Which are ours, which are yours, which are nobody's without a work order.
- Chemistry
Your approved disinfectants and sporicides, the rotation, contact times, and where the lot numbers are recorded.
- Returns and supply
Where the low wall returns are, what we wipe and what we never block.
- Records
The log format your quality team expects, by room and lot, and who signs it.
Inside the room
Care follows the air.
A simplified cleanroom: HEPA supply above, laminar downflow across the work surface, low wall returns, the gowning door. Each zone has its own rule in the scope.
Ceiling grid and filter faces are the facility's; we clean the frames only where the scope says so.
We work with the airflow, top down and in from the cleanest wall, never across the work surface.
Grilles wiped on the schedule and never blocked by a cart or a bucket.
Approved wipes, overlapping strokes, the site's chemistry and contact time.
Entry in the posted sequence; the tacky mats changed on the count written in the scope.
What we write down
What goes into the scope.
Rooms and order
Every room by name, the cleaning order through the cascade, and the airlock rules.
Method and chemistry
Wipe and mop methods per surface, the approved products, the rotation and the contact times.
Records and sign-off
The log by room and lot, the training records for the crew, and who releases the room.
The suite, the gowning room, the record
Questions about cleanroom cleaning
Do your crews gown to our procedure?
Yes. The gown-in sequence is yours; the crew is trained to it on site before the first shift, and the training is on record.
Whose chemistry do you use?
Yours, on your rotation, unless the scope says otherwise. Lot numbers go in the log.
Can you clean around a validated process?
We clean what the scope names, when the room is released, and nothing else. Equipment interiors and process surfaces stay with your team unless a work order says otherwise.
