To evaluate scheduled commercial cleaning, inspect high-touch surfaces like doorknobs and light switches for residue, check for dust buildup on vents and baseboards, and note any lingering odors. A reliable cleaner maintains a consistent checklist, uses color-coded cloths to avoid cross-contamination, and adjusts frequency based on foot traffic. Spot-checking randomly throughout the week, rather than right after cleaning, reveals true effectiveness.
