The answer to 'when to clean sanitizing' is that you should sanitize high-touch surfaces in your home on a regular basis, typically once a week or more often if someone in your household is sick. Sanitizing helps kill germs and bacteria that can cause illness and spread infection.
Some key areas to focus on for sanitizing include doorknobs, light switches, countertops, sinks, toilets, and any other frequently touched surfaces. You can use a disinfecting spray or wipe, or make your own sanitizing solution with bleach and water. Be sure to follow the product instructions carefully and allow the surface to remain wet for the recommended contact time to ensure effective disinfection.
