Cleaning and Disinfecting a Room Safely

For ordinary visible soil, a suitable cleaning method may be sufficient. Use a disinfectant only when appropriate to the task or current guidance, and choose a product labelled for the exact surface and purpose.

Check approved surfaces, pre-cleaning, dilution, amount, contact time, ventilation, protective equipment and rinsing. Keep people and pets away as directed. Never mix disinfectants with bleach, acids, ammonia or other cleaners.

Use only methods allowed by device and surface makers. Keep liquid out of electronics, sockets and openings. For food-contact surfaces, follow product directions about rinsing before use.

Do not spray or fog a room, duct, fan or air-conditioning system unless a qualified professional and the product instructions specifically authorize that application. Ventilation and air filtration are separate matters and should follow building and equipment guidance.

If there has been a specific exposure, illness or contamination concern, follow appropriate current public-health or workplace guidance. Cleaning cannot diagnose, prevent or treat disease, and building-system maintenance requires suitable specialists.
