Commercial cleaning is often bought on price per hour, which tells you almost nothing about what you will receive. What matters is the scope: which tasks, at what frequency, to what standard, and how that is verified.
Cleaning, sanitising and disinfecting are different
Cleaning: Physically removes soil, grease and debris. This is the step that does most of the work, and nothing else functions without it.
Sanitising: Reduces microorganisms on a cleaned surface to a safe level. Applied to an unclean surface, it largely fails.
Disinfecting: Kills a broader range of organisms, and needs the contact time stated on the label — wiping a product straight off does not disinfect.
What a scope of works should specify
Task list by area — floors, amenities, kitchens, glass, waste removal, high-touch points.
Frequency for each task, including periodic work such as deep cleans and floor treatments.
Who supplies consumables, and who restocks them.
Access, keys, alarm procedures and hours of work.
How performance is checked, and what happens when something is missed.
Cleaning is the foundation of pest control
Pest activity and cleaning standards are directly linked. Food debris under equipment, grease in floor waste, overflowing bin stores and spillage that is left to dry all provide exactly what pests need to establish and breed.
On sites where pest activity keeps recurring despite treatment, the cause is very often a cleaning or storage issue rather than a treatment failure. Fixing the housekeeping usually does more for long-term control than another chemical application.
Storage and stocking
Goods stacked directly against walls make inspection impossible and create ideal harbourage. Leaving clear space between stock and walls allows both cleaning and visual inspection, and rotating stock so older items are used first prevents forgotten product becoming a food source.
