‌●Use cleaning tools with anti-hair-shedding treatment to avoid secondary pollution.

●Do not use a hard-bristled brush to scrub the floor to prevent scratching the floor tiles.

●The pH value of the cleaning agent should be controlled at 6.5–7.5 (especially for floor tiles) to avoid corroding the surface.

●For disinfection, use a chlorine-containing disinfectant with an effective chlorine concentration of 500 mg/L or 250 mg/L chlorine dioxide, and let it act for 30 minutes before rinsing with clean water to remove any residues.

Standardized process: Clarify the cleaning steps, frequency, and acceptance criteria for each area (such as no stains on the floor and no odor in the bathroom).

‌Individual responsibility: Adopt a system of divided responsibility and lump sum payment, linking cleaning quality to performance.

‌Multi-level inspection: self-inspection by cleaning staff → irregular patrols by supervisors → comprehensive weekly inspection by the quality department.

‌Customer feedback: Collect issues through suggestion boxes or online reviews, and dynamically adjust cleaning strategies.
