Immediate response versus scheduled cleaning
A spill has a short window in which it is easy to deal with. Absorbent granules or pads applied within minutes remove most of the volume and stop it spreading into traffic lanes. A cleaner attending that evening cannot recover that window, and treating the residue is a fundamentally different task with a different chemical and a different result expectation.
The scope should therefore say plainly that immediate response is a site function with site-supplied materials, and that scheduled attendance addresses residual staining and general condition. That is not a way of avoiding work. It is how the two activities are actually most effective, and it prevents a site from relying on a cleaning visit as its spill control measure. Recording the location of the kit, and confirming who is trained to use it, is a short conversation at the walkthrough that clarifies the arrangement for both parties.
