How to properly clean an office, room by room
A clean, bacteria-free office genuinely lifts mood and productivity — and most of the difference comes down to working in the right order, not working harder.
A deep office clean is a different job to the daily tidy-up most workplaces already manage — bins emptied, desks wiped, floors done. It's the layer underneath that gets missed for months at a time: behind monitors, inside cupboard handles, under the kitchen sink. Done properly, it doesn't take long, and it makes a bigger difference to how the space feels than most people expect.
What to have on hand
A short list covers most of an office: dishwashing liquid for the kitchen, a small soft-bristled brush for keyboards and vents, isopropyl alcohol for electronics and touch surfaces, microfibre cloths, disinfecting wipes, a vacuum, a bin, a couple of empty boxes for decluttering as you go, a disposable duster for high shelves and light fittings, and a disinfectant bathroom cleaner. Nothing specialist — the value is in using the right one for each surface rather than one all-purpose spray for everything.
The order that actually works
Work top to bottom and clean to dirty, in roughly this sequence:
- Desks and surfaces first. Clear clutter into boxes before wiping — cleaning around mess just moves it.
- Electronics next, with isopropyl alcohol on a cloth rather than sprayed directly, and a soft brush for keyboard gaps and vents. If you're using anything stronger than a wipe, safety glasses are worth it.
- Cabinets and shelving — empty, wipe, and only put back what's actually still needed. This is where the empty boxes earn their keep.
- Declutter before you reorganise, and reorganise before you touch the floor. Doing it in the other order means re-cleaning the same square metre twice.
- Kitchen areas need fresh cleaning solution partway through — a cloth that's already picked up grease just smears it around instead of lifting it.
- Bathrooms last, treated as the highest-germ area in the building, with their own cloths and cleaner never crossed over from the kitchen.
- Floors at the very end, once everything that could drop dust or debris back onto them has already been done.
The spots that get missed: behind and underneath monitors, the underside of desk drawers, door handles and light switches, the rim and base of the kitchen bin, and anywhere a keyboard or mouse has sat for months without being lifted. None of these show up on a quick visual check — they're exactly what a proper deep clean is for.
For a shop, clinic or office on a regular after-hours schedule, this level of clean is worth building into the routine rather than treating as a once-a-year event — see our commercial cleaning page for pricing and what's included, or get in touch for a fixed quote based on your floor plan and hours.
