Which of the following actions ensures effective disinfection of countertops?

Selecting an EPA registered disinfectant is crucial for ensuring effective disinfection of countertops. These disinfectants have been specifically tested and proven to be effective against a range of pathogens when used according to the manufacturer's instructions. They have been regulated for safety and efficacy by the Environmental Protection Agency (EPA), meaning they have undergone rigorous testing to validate their claims against viruses, bacteria, and fungi.

Simply wiping with a paper towel does not provide the necessary antimicrobial action needed to kill germs. Although it can help clean surfaces, it does not ensure disinfection on its own. Spraying with water may clean the surface but lacks the necessary components to kill pathogens. Similarly, using a diluted soap solution can help remove dirt and some microorganisms, but it is not effective in achieving true disinfection since soap primarily works to remove dirt rather than kill microorganisms effectively. Thus, relying on an EPA registered disinfectant is the most reliable way to ensure countertops are effectively disinfected.
