The answer to 'how often to clean sanitizing' is that most experts recommend sanitizing high-touch surfaces in the home at least once a week. This includes things like door handles, light switches, countertops, and faucets. Proper sanitizing helps kill germs and bacteria that can cause illness and keep your home clean and healthy.
For areas that see a lot of use or have the potential for more germs, like bathrooms, you may want to sanitize a few times per week. It's also a good idea to sanitize after someone in your home has been sick. The specific frequency will depend on the needs of your household, but weekly sanitizing is a good general guideline.
