5.Procedure
- 5.1
Clear the area and place signage
Cleaning TechnicianMove small obstacles and trip hazards out of the way, and place wet floor signs at every entrance to the area before starting.
Checkpoint: A wet floor sign is visible from every entrance before mopping begins.
- 5.2
Dust mop or sweep first
Cleaning TechnicianDust mop or sweep the entire floor to remove loose dirt, grit and debris before applying any liquid, working from the far end toward the exit.
- 5.3
Mix the cleaning solution
Cleaning TechnicianMix the floor cleaning solution at the dilution ratio on the product label, using the two-bucket method with one bucket for clean solution and one for wringing.
Warning: Using solution that is too strong can leave a sticky residue or damage some floor finishes.
- 5.4
Mop in sections
Cleaning TechnicianMop one manageable section at a time using an overlapping figure-eight motion, working backward toward the exit so you do not walk on the wet floor.
- 5.5
Change the solution when dirty
Cleaning TechnicianRinse and refill the mop bucket with fresh solution once the water looks visibly dirty, rather than continuing to spread dirty water across the floor.
- 5.6
Detail edges and corners
Cleaning TechnicianUse the corner and edging tool to clean along baseboards, under fixtures and in corners the mop cannot reach.
- 5.7
Treat stubborn spots
Cleaning TechnicianApply extra solution and light agitation to gum, scuff marks or dried spills that did not lift during regular mopping, then rinse the spot clean.
- 5.8
Allow the floor to dry
Cleaning TechnicianLeave the wet floor signs in place and allow the floor to air dry fully before reopening the area to foot traffic.
Checkpoint: The floor is fully dry to the touch before any signage is removed.
- 5.9
Inspect for missed spots
Cleaning TechnicianWalk the floor once it is dry and check under good lighting for streaks, missed spots or residue, and re-mop any area that does not pass.
- 5.10
Remove signage and return furniture
Cleaning TechnicianOnce the floor is confirmed dry, remove the wet floor signs and return any furniture moved earlier to its original position.
- 5.11
Report floor surface damage
Cleaning TechnicianNote any cracked, lifted or loose flooring found during cleaning in the work order app with the exact location.
6.Quality checks
- โNo streaks, residue or missed spots remain once the floor is fully dry.
- โWet floor signage is placed before mopping starts and removed only after the floor is dry.
- โMop solution is mixed at the dilution ratio on the product label.
- โEdges, corners and baseboards are free of built-up dirt on spot checks.
7.Records
- โFloor cleaning checklist
- โFloor damage reports
- โSolution dilution log where required by the site
8.KPIs
- โAverage floor drying time before reopening
- โSlip or fall incident rate on cleaned floors
- โPercentage of floor areas passing spot inspection
- โFloor surface damage reports per month
9.Common mistakes
- โRemoving wet floor signs before the floor is fully dry.
- โMopping with dirty solution instead of changing it.
- โSkipping the dust mop step and mopping over loose grit.
- โUsing too strong a solution and leaving a sticky residue.
