The line at the laboratory door
Inside a laboratory, cleaning is part of the facility's own procedures, performed by staff who know what is on the bench, what is in progress and what the disposal requirements are. A general cleaner cannot make those judgements and should not be asked to. The line at the door is not a limitation of willingness; it reflects who holds the necessary knowledge.
That leaves a substantial and genuinely useful scope outside the door. Corridors, write-up areas, meeting rooms, amenities, goods receipt, general stores, plant spaces and the office component of a research building are all ordinary commercial and industrial cleaning. Doing those well, on a stated schedule, is worth more to a facility than an uncertain promise about the lab. Setting that out plainly at the quoting stage is more useful to a facility than an assurance that later has to be qualified after an incident.
