The answer to 'when to clean sanitizing' is that you should clean and sanitize high-touch surfaces in your home on a regular basis, typically once a week or more frequently as needed. Proper sanitizing helps kill germs, bacteria, and viruses that can cause illness and maintain a healthy, hygienic environment.
Some key areas to focus on include doorknobs, light switches, countertops, faucets, toilets, and other frequently touched surfaces. You'll want to use EPA-registered disinfectants or a diluted bleach solution to effectively sanitize these surfaces. Be sure to follow the product instructions carefully for optimal cleaning and disinfection.
