Cleaning techniques and procedures (residential and light commercial)
Cleaning techniques and procedures
This domain tests repeatable residential and light-commercial procedures: pre-vacuum, precondition, agitate, dwell, extract/rinse, spot, groom, dry, and inspect. The method must fit the site, fiber, soil, and occupancy.
Core rules
- Residential: move/protect furniture, pre-vacuum edges and traffic lanes, pre-test, prespray, agitate, dwell, extract with overlapping passes, detail edges, groom, dry with airflow, and do a post-inspection.
- Light commercial: plan after-hours or low-traffic work, control cords and slip hazards, use signage, protect fixtures, and choose interim (encapsulation/bonnet) or restorative HWE based on soil and downtime.
- Spotting sequence: remove solids, test, apply from outside in, dwell, blot/extract, rinse, dry. Use cold water for protein; tannin spotter for coffee/tea; solvent for grease/ink; rust remover for rust.
- Urine and pet contamination: find all deposits, extract, treat, check backing/subfloor, and control odor; wicking may require repeat treatment.
- Drying: air movers and dehumidification, open doors, lift furniture blocks, and verify before removing equipment.
- Post-inspection: compare to pre-existing record, groom, review care, and document remaining stains.
Worked example
A small office has glued-down loop carpet in a reception area and coffee spills at a desk. The tech plans after-hours work, uses low-moisture encapsulation on the loop carpet to reduce downtime, pre-tests, and spot-treats the coffee with a tannin spotter and extraction. He sets signage and air movers. Reasoning: glue-down loop tolerates low moisture, interim cleaning fits the business schedule, and tannin chemistry matches coffee.
Traps
Over-wetting seams and backing; using the same spotter for protein and tannin; cleaning occupied commercial space without barriers; and skipping post-inspection. Document what remains-customer expectations are part of the procedure.
