Laboratory cleaning is contamination-controlled cleaning of a controlled environment, where the wrong product or a crossed cloth can invalidate results or breach containment. Optus Glean UK cleans laboratories to documented, COSHH-assessed method statements, respecting the boundary between cleaner-cleanable zones and areas only lab staff may touch, using trained, PAYE-employed operatives.
What makes laboratory cleaning different from office cleaning?
A laboratory is a controlled environment: surfaces, air, and equipment are managed to protect the integrity of experiments and, in containment labs, to prevent the escape of biological or chemical agents. General cleaning is confined to defined cleaner-cleanable zones — floors, non-critical surfaces, waste and washrooms — while benches, fume cupboards, and equipment remain the responsibility of lab staff unless a specific protocol says otherwise. We agree that boundary in writing before the first clean, so nothing critical is touched by mistake.
How do you control contamination and chemical risk?
We use dedicated, colour-coded equipment so laboratory-zone cloths and mops never cross with other areas, and every product is assessed under the COSHH Regulations — critical where residues could react with reagents or corrupt results. Method statements specify approved products, dilution, contact times, and the PPE required, and we follow the lab's own spill, decontamination, and waste-segregation rules rather than imposing generic ones.
How do you handle containment and access restrictions?
In containment or higher-hazard areas, access is controlled and cleaning is only carried out under the lab's supervision, permits, and decontamination status. We train operatives on gowning, entry/exit discipline, and the specific restrictions of each zone, and we never enter or clean a restricted area without sign-off from the responsible scientist or facility manager.
What vetting and training do your laboratory cleaners have?
Every operative is PAYE-employed on guaranteed hours, background-checked to the level the site requires, and trained to the laboratory's documented protocols before their first shift. For labs within healthcare or research settings that request it, we provide Enhanced-DBS-checked operatives — the same directly-employed, vetted model we use across our healthcare cleaning work.
