As a rule, the more people use your washroom, the more frequently it will need cleaning and or disinfection.
If there are only a few employees sharing the same washroom, do a thorough cleaning and disinfection once per day and disinfect frequently touched surfaces at least twice a day. However, if clients and the public have access to your washroom, disinfect it every two to three hours.
If your building is in an outbreak zone, increase the frequency of disinfection to give employees and clients peace of mind.
Make sure the person responsible for disinfection has the proper tools, disinfectant, and training in how to use them correctly, including the exact location of germ hot spots, and adequate product contact time to ensure proper disinfection has taken place.
