Controlled environment cleaning for Sydney pharmaceutical, medical device, compounding, electronics and research facilities. Gowned entry, unidirectional wiping, clean-to-dirty sequencing, facility-validated agents and a documented record for every room and every entry.
Cleanroom cleaning targets particle counts rather than visible soil, using low-shedding consumables, unidirectional wiping and clean-to-dirty sequencing under the facility own validated procedures. Specialist rates in Sydney generally run between $55 and $75 per hour. Every entry is gowned, and every clean is recorded by room, date, operator and agent.
A cleanroom is classified by how many airborne particles of a given size are permitted in a cubic metre of its air. That single measurement changes what cleaning means. A room can look immaculate and fail; it can have a visible mark on a wall and pass. The job is not to make surfaces look good, it is to remove and not generate particulate, and to do it without disturbing the airflow pattern the room depends on.
The single largest particle source in any cleanroom is the person standing in it. Human skin sheds continuously, and shedding rate rises sharply with movement speed. That is why gowning exists, why operators are taught to move deliberately rather than briskly, and why a cleaner who works the way they would in an office actively degrades the room they are trying to clean. Fast circular wiping, shaking out a cloth, dragging a bucket, or reaching across a critical surface all put particulate into suspension.
Technique follows from that. Wipes are folded into quarters and used one face at a time, moved in a single direction with overlapping passes, and discarded rather than rewetted. Surfaces are worked from the top down and from the cleanest zone outward toward the airlock, never back toward the critical area. Mop covers are changed on a defined area basis rather than when they look dirty. Nothing is sprayed into open air where the aerosol can travel; solution is applied to the wipe.
Assessment against your classification, procedures and validated agent list. No lock-in contract.

Staff assigned to a Sydney cleanroom are trained on the facility own gowning sequence before they ever work a shift in it, because gowning order is designed so that a garment is never contaminated by the step that follows. Coveralls, hoods, boots, gloves, masks and eyewear go on in the order the site specifies, in the zone the site specifies, and degowning reverses it with the same discipline. Getting the order wrong defeats the garment entirely.
Airlocks exist to hold a pressure differential and to give particulate somewhere to settle before it reaches the room. That only works if the doors are interlocked in practice as well as in design, so staff wait rather than propping, and never hold both sides open to pass equipment through. Cleaning equipment itself enters through the material airlock or pass-through with the same wipe-down and staging the facility requires of any other item, and dedicated equipment for a classified area never leaves it.
The gowning room is a cleaning target in its own right and often a neglected one. It accumulates fibre from garments, skin particulate from changing, and footfall contamination at the step-over bench. Cleaning it on a proper frequency, in the correct direction, does more for the room beyond it than most people expect, because everything and everyone entering the classified space passes through it first.
We do not bring our own chemistry into a validated environment. Cleaning and disinfecting agents come from the facility approved and validated list, prepared at the concentration the site has qualified, and applied for the contact time that qualification supports. Substituting a product because it is cheaper or more familiar invalidates the facility own evidence, and no cost saving justifies that.
Many Sydney facilities operate an agent rotation, alternating between disinfectants with different mechanisms and periodically applying a sporicidal agent, because organisms that survive one chemistry may not survive another and spores survive most routine disinfectants entirely. Rotation is only meaningful if it is followed on schedule and recorded, so the rotation calendar is built into the cleaning schedule rather than kept in a separate document nobody consults.
Residue management matters as much as efficacy. Disinfectants leave films that build up on surfaces over repeated application, and in some rooms that residue is itself a contamination and a visual inspection problem, so a rinse step with purified water is scheduled at the interval the facility specifies. Where alcohol is used it is understood as a rapid-acting agent with no sporicidal claim and a short contact time, not as a substitute for a full disinfection step.
Sydney's controlled environment work is concentrated in a few industry clusters. Pharmaceutical and complementary medicines manufacturing sits largely in the western and south western industrial corridors, around Smithfield, Wetherill Park, Ingleburn, Seven Hills and Silverwater, where GMP-licensed sites run classified production and packaging suites alongside conventional warehousing. Medical device assembly and sterile packaging operate in similar precincts with tighter particulate requirements and often an electrostatic discharge control layer as well.
Compounding pharmacies and aseptic preparation units are found in and around hospital campuses and in standalone facilities across the metropolitan area, and they run small, high-grade suites where the workload per square metre is very high. Research cleanrooms sit on university and institute campuses at Macquarie Park, Camperdown, Randwick, Kensington and Westmead, frequently combining classified space with laboratory areas that have their own containment requirements.
Electronics, optics and photonics facilities add particulate sensitivity of a different kind, where a single fibre on an optical surface or a static discharge is the failure rather than a microbial count. Each of these clusters has different rules and the scope reflects them. Adjacent uncontrolled laboratory space is normally covered under our laboratory cleaning scope, and surrounding manufacturing floors under factory cleaning.
In a regulated facility, work that is not documented did not happen. Every cleanroom clean we perform is recorded against the room, the date and time, the operator, the agents and concentrations used, and the batch or lot of consumables where the facility tracks them. Those records live where the facility wants them, in its own system where one exists, so they are available during an inspection without a request to a contractor.
Training records are held to the same standard. Each operator assigned to a classified area has documented training in gowning, entry and exit, technique, agent handling and the facility specific procedures, with retraining at the interval the site requires and after any procedure change. Staff are assigned to the site rather than rotated through it, because competence in a controlled environment is built over months and lost in a week of unfamiliar faces.
When environmental monitoring shows an excursion, the cleaning record becomes evidence in the investigation. That is the real reason for the discipline: not to satisfy a form, but so that when a facility has to explain a result to a regulator or a customer auditor, the cleaning contribution can be established rather than guessed at.

In a normal building the cleaner removes what is visible. In a cleanroom the target is particles you cannot see, measured in counts per cubic metre at defined sizes, and the cleaner is themselves the largest particle source in the room. That inverts the whole method. Everything is chosen for how little it sheds, motion is slow and directional rather than fast and circular, wipes go in one direction and are folded and replaced rather than reused, and the sequence always runs from the cleanest zone toward the least clean so contamination is never carried backwards.
We work in classified environments across the range Sydney industry actually operates, from lower-grade controlled and background areas through to higher-grade cleanrooms adjacent to critical zones, in pharmaceutical and complementary medicines manufacturing, medical device assembly, compounding pharmacy, electronics and optics, and research facilities. The scope, gowning requirement and agent list are set by the facility classification and its own validated procedures. We work to the site protocol rather than imposing a generic one.
Specialist cleaning in Sydney generally runs between $55 and $75 per hour, and cleanroom work sits at the specialist end of that band because of the gowning time, the consumable cost and the documentation involved. Gowning, degowning and airlock transit consume real minutes on every entry, and a room requiring multiple entries per shift costs more to service than its floor area suggests. Every facility is quoted after a site assessment against its own classification and procedures.
Low-linting or non-woven wipes and mop covers appropriate to the room grade, stainless or polypropylene frames with no shedding components, dedicated buckets and trolleys that never leave the classified area, and sterile or filtered consumables where the grade requires them. Cleaning and disinfecting agents come from the facility validated list, applied at the concentration and contact time the facility has qualified. Where a rotation between agents is required to address sporicidal coverage, we follow the site rotation schedule rather than substituting products.
Yes, without exception. Staff assigned to a cleanroom are trained in the facility gowning sequence, airlock and pass-through discipline, material transfer procedure and behavioural requirements inside the room, including movement speed, talking, and keeping clear of unidirectional airflow paths over critical points. Personal items, cosmetics, jewellery and non-approved paper do not enter. Staff are also trained on why each rule exists, because rules understood are followed and rules memorised are not.
Cleaning is one of the controls that environmental monitoring measures, so the two schedules have to be coordinated rather than run independently. Monitoring plates and settle plates are placed and recovered by the facility quality team, and cleaning is timed around them so a result reflects the room state the facility intends to test. If monitoring shows an excursion, the cleaning record for that room, that date, that operator and that agent is part of the investigation, which is exactly why the record has to exist in usable form.
Trained, gowned, dedicated crews working to your validated procedures, with the documentation your auditors expect.
