In high-touch area disinfection programs, which surfaces are considered highest priority?
Answer: Door handles, light switches, elevator buttons, and faucet knobs
High-touch surfaces like door handles, light switches, elevator buttons, and faucets are most frequently contacted and pose the greatest transmission risk.
What is the key advantage of microfiber cloths over traditional cotton cloths in cleaning?

Microfiber's split fiber structure creates edges that physically trap and remove bacteria and particles more effectively than cotton fibers.
When should a cleaning technician change their mop water during routine floor mopping?
