What does a cleaning result tell you?
A tidy kitchen or bathroom shows a presentation change. It does not document which disinfectant was used, whether it suited the material or how it was applied. For a deep-clean booking, list the rooms and tasks first and ask separately about any intended disinfection.
Australian community-cleaning guidance explains that cleaning before disinfection matters because dirt can interfere with the disinfectant. Treat preparation and disinfection as a sequence rather than assuming one replaces the other.
Which label details matter?
The TGA advises checking intended surfaces, directions, dilution where specified, application and contact time. Contact time is the period the product needs to act as directed; wiping it away immediately may not follow the instructions. There is no universal time for every product.
Keep products separate. The TGA warns that mixing cleaners and disinfectants can produce hazardous fumes or change their effect. Follow ventilation and handling instructions and store products safely.
What should the booking cover?
Describe why treatment is requested, the rooms and touch points, surface materials and items needing protection. Agree whether preparation, cleaning, disinfection and subsequent access instructions are included. Room count alone does not describe all these tasks.
Mould or a continuing odour may involve a different problem. Keep those concerns clear rather than assuming disinfection will also repair a moisture source or identify an indoor-air contaminant.
Questions about this problem
Does a fresh smell prove an area was disinfected?
No. Fragrance does not document the product, surface compatibility, application or contact time. Confirm the actual work and instructions.
Can I mix products for a stronger treatment?
Do not mix cleaning or disinfecting products. Follow the selected product’s label; mixtures can produce dangerous fumes and may not work as intended.
Does home disinfection mean sterilisation?
No. Agree the intended surface treatment and scope. A domestic cleaning or disinfection booking is not a promise that a whole property is sterile.

Start with the reason for the work and the surfaces involved. Keep cleaning, product instructions and disinfection distinct, then use the FAQ questions to agree the assessment and booking scope.
