Submicron Data Center Cleaning — ISO 14644-1 & ISO 8502-9 Testing

What We Do

Cleaning built for critical environments.

Precision cleaning that protects uptime, extends hardware life and keeps your facility compliant.

Surface Cleanliness Testing

During cleaning operations, our technicians use the Iontester™ to confirm that surface cleanliness meets the requirement of <5 micrograms ionic contamination — including chlorides — per cm².

Ionized Cleaning

Standard cleaning fails because submicron particles cling via electrostatic attraction. We use ionized air, brushes, and cloths to safely neutralize static charges on live equipment without disruption. Powered by our proprietary IONDuster™ system, our actively charged brushes deliver targeted ions on contact to break this static bond — effortlessly releasing microscopic contamination for complete removal via ULPA vacuuming.

ULPA Vacuum Cleaning

Once contamination is released, it's captured with a ULPA-filtered vacuum certified to remove particles down to 0.12 microns — far below what standard HEPA or janitorial vacuums can trap. This is specialized cleanroom equipment operated by trained cleanroom technicians, not general facilities staff, and it's a core reason our results hold up to certified air and surface testing.

Ionic Contamination

Clean to the eye. Contaminated underneath.

Removing ionic contamination is a different job from removing dust — and a far more dangerous one to leave undone. A surface can look completely clean while still carrying a heavy load of corrosive chlorides.

We once cleaned a data center after a particle incident caused by its fire-suppression system discharging, even though there was no actual fire. A few months later, the customer began noticing corrosion-related downtime. By the time we inspected the facility, every surface looked spotless to the eye — but the surface chemistry told a different story.

250µg Cl⁻/cm² measured

Our technicians measured chloride levels of roughly 250 micrograms per cm² on surfaces that appeared visually clean — fifty times above the 5 micrograms per cm² limit recognized for electronic equipment.

Why Standard Cleaning Falls Short

We've found that standard janitorial cleaning methods do not effectively remove chloride-laden dust — they can move it around or embed it further, rather than lifting it off the surface.

The IonDuster™ Method

One of our key tools is the IonDuster™, which uses an oppositely charged brush to attract and remove charged ionic particle contamination from equipment, cable trays, ceiling infrastructure and more — without disrupting live operations.

Certified Cleanliness

We don't just clean — we prove it.

Every cleaning engagement can be backed by independent measurement, so you have documented, standards-referenced evidence of the result — not just a visual inspection.

Air Cleanliness Testing — ISO 14644-1 Class 8

We perform airborne particle counting in your data hall and certify the result against ISO 14644-1 Class 8, giving you an auditable record of air cleanliness after every job.

Surface Cleanliness Testing — ISO 8502-9

We measure residual soluble salts and ionic contamination on rack and floor surfaces per ISO 8502-9, confirming that the corrosive residues behind board and connector failures have actually been removed, against a threshold of <5 micrograms ionic contamination per cm².
