Interior phasing spreadsheets (interior turnkey vs phased) differ from grime cadence, yet both punish magical thinking.
| Layer | Often suffices |
|---|---|
| Open shelf dust Film | Weekly dry then damp policy |
| Kitchen vertical tile film | Fortnightly degrease dwell |
| Bathroom silica + soap scum | Monthly targeted acid discipline (with stone caveats) |
| Post-renovation flat | Standalone silica purge before routine cadence resets |
| Festive hostage guests | Seven-day escalation band |
Deep clean = longer mop? Different chemistry, ladders, grout dwell; request explicitly.
