Office Deep Cleaning Process: Step-by-Step Explained

The full process at a glance

Here's the order a proper office deep cleaning job follows, from first visit to handover:

1. Site survey and planning
2. Workstation sanitization
3. Carpet shampooing
4. Chair & sofa cleaning
5. Glass cleaning
6. Pantry & washroom deep clean
7. Floor scrubbing
8. Walk-through and handover

Step 1: Workstation sanitization

Our crew completes "workstation sanitization" using the appropriate equipment — typically glass squeegees and extension poles for high glazing — and the right safety gear for this step, before photographing the result and moving on.

This is usually the step that reveals the real condition of the site, which is why the earlier site survey matters — it sets expectations for what this step will actually involve.

Step 2: Carpet shampooing

Our crew completes "carpet shampooing" using the appropriate equipment — typically colour-coded microfiber cloths to prevent cross-contamination — and the right safety gear for this step, before photographing the result and moving on.

Getting this step wrong is one of the more common ways a rushed job falls short: a deep clean rushed to save time typically skips high-dusting (vents, lights, top of cupboards), leaves washroom grout and drain odours untreated, and polishes floors without stripping old residue first — so the shine doesn't last.

Step 3: Chair & sofa cleaning

Our crew completes "chair & sofa cleaning" using the appropriate equipment — typically single-disc and ride-on floor scrubbing machines — and the right safety gear for this step, before photographing the result and moving on.

Getting this step wrong is one of the more common ways a rushed job falls short: a deep clean rushed to save time typically skips high-dusting (vents, lights, top of cupboards), leaves washroom grout and drain odours untreated, and polishes floors without stripping old residue first — so the shine doesn't last.

Step 4: Glass cleaning

Our crew completes "glass cleaning" using the appropriate equipment — typically industrial dry and wet vacuum cleaners — and the right safety gear for this step, before photographing the result and moving on.

Getting this step wrong is one of the more common ways a rushed job falls short: a deep clean rushed to save time typically skips high-dusting (vents, lights, top of cupboards), leaves washroom grout and drain odours untreated, and polishes floors without stripping old residue first — so the shine doesn't last.

Step 5: Pantry & washroom deep clean

Our crew completes "pantry & washroom deep clean" using the appropriate equipment — typically injection-extraction carpet and upholstery machines — and the right safety gear for this step, before photographing the result and moving on.

Getting this step wrong is one of the more common ways a rushed job falls short: a deep clean rushed to save time typically skips high-dusting (vents, lights, top of cupboards), leaves washroom grout and drain odours untreated, and polishes floors without stripping old residue first — so the shine doesn't last.

Step 6: Floor scrubbing

Our crew completes "floor scrubbing" using the appropriate equipment — typically steam cleaners for grout, washrooms and kitchens — and the right safety gear for this step, before photographing the result and moving on.

Getting this step wrong is one of the more common ways a rushed job falls short: a deep clean rushed to save time typically skips high-dusting (vents, lights, top of cupboards), leaves washroom grout and drain odours untreated, and polishes floors without stripping old residue first — so the shine doesn't last.

Crew size and duration

A typical 2,000–5,000 sq. ft. office is cleaned by a crew of 4–8 staff with a supervisor in 4–8 hours overnight or over a weekend. Large-format sites like malls and hospitals run in planned zones with a rotating crew so operations are never fully shut down.

Quality checks during the process

Our supervisor checks for these before marking any step complete:

• No odour in washrooms, pantry or carpeted areas a day after the clean
• Floors and glass are streak-free, not just damp-mopped
• High areas (vents, lights, tops of cupboards) are visibly dust-free
• A supervisor walk-through report is provided with photos
• Staff or visitor complaints drop in the weeks after the service

Handover and reporting

The supervisor walks through the completed work with you, shares before/after photos and a written report, and agrees the next service date before the crew leaves.

What goes wrong when steps are skipped

A deep clean rushed to save time typically skips high-dusting (vents, lights, top of cupboards), leaves washroom grout and drain odours untreated, and polishes floors without stripping old residue first — so the shine doesn't last. The space looks clean on day one but reverts within a week, forcing another paid visit sooner than planned.

Office Deep Cleaning is a good example of exactly this.
