Dose, dilution and why stronger is a mistake
Every residue problem in this catalogue starts the same way: more product than the surface can rinse off. Professionals remove the decision from the person holding the bottle.
In detail
A cleaning product is specified as a concentration, and the concentration is part of the claim. Above it, the extra product does no extra work — it stays behind. Residue is sticky, residue attracts soil, and a surface cleaned too strongly gets dirty faster than one cleaned correctly, which is why rapid re-soiling is blamed first on unrinsed detergent rather than on traffic. Below it, the product does not work and the temptation is force, which abrades. Professional practice does not fix this by telling people to read the label. It engineers the decision away: automated dispensing and auto-dosing mix at the specified ratio every time, so dilution does not depend on somebody's eye or how dirty the floor looks. The same specifications give a DWELL — five to fifteen minutes on a resilient floor — whose upper bound is not about time: do not let the solution dry, because a dried cleaner is a residue. The household version is a measure and a rinse. When a trade body specifies a quarter teaspoon of detergent to a cup of water and says never to go stronger, it is making a claim about damage rather than writing a recipe.

Cleaning accommodation and facilities: COSHH essentials, control approach 1
Health and Safety Executive (HSE), United Kingdom · Government or regulator
Relied on for: That professional control includes providing equipment with auto-dosing and cleaning-in-place and automated dispensing systems, and following label instructions for use. (states this directly)
Verification: a person has read the passage relied on.
Read on — The hazards list, the control procedures, PPE, skin care and the schedule. Supports the claim as stated. Supplies the professional pillar's spine. Everything a household reader does is chemistry and technique; what a regulator adds is dosing control, colour coding, substitution, ventilation rates and a written schedule — none of which this register held, and all of which are the actual difference between cleaning and being paid to clean. It also puts the never-mix rule in a regulator's words for the first time.
Luxury Vinyl Tiles and Planks: Maintenance Instructions
Tarkett (Johnsonite), 2016 · Manufacturer documentation
Relied on for: That the dilution ratio depends on soil conditions and follows the manufacturer's label, that the solution dwells for 5 to 15 minutes, and that the solution must not be allowed to dry. (states this directly)
Verification: a person has read the passage relied on.
Read on — Post-installation cleaning, preventive care, routine daily cleaning, periodic deep cleaning and the product reference chart. Supports a wider statement — our claim was widened. Gives the register the professional maintenance REGIME rather than another list of prohibitions. Tiered maintenance, a machine with a stated speed, a pad with a stated colour, a dwell time with an upper bound, and barrier matting as a cleaning decision rather than a doormat — these are what a facilities specification contains and a household care page never does. The insecticide-and-disinfectant warning is the sprint's best example of a cleaning failure caused by something that was not aimed at the floor.
Consumer Floor and Furnishings Care Information: carpet topics
Institute of Inspection, Cleaning and Restoration Certification (IICRC) · Trade or professional body
Relied on for: That rapid re-soiling is attributed first to detergent or soap residues not effectively rinsed during cleaning. (states this directly)
Verification: a person has read the passage relied on.
Read on — All twenty-five numbered topics. The damage sections (17-25) and the animal, mould and residue sections carry most of what was new. Supports a wider statement — our claim was widened. The single richest source this register has acquired. It supplies six mechanisms nobody here held — wicking, cellulosic browning, filtration soiling, rapid re-soiling, delamination and phenolic yellowing — and every one of them is a case of DIRTY VERSUS DAMAGED, the distinction this catalogue is built on. It also closes the pet-odour question Sprint 48 left partial: the reason the smell returns in humid weather is a reservoir in the backing and padding that surface cleaning never reached, not the rehydrating uric-acid story consumer pages tell.
