A common misconception is that surfaces don't need to be wiped down if an Electrostatic Sprayer is used for disinfecting. A layer of grime or dirt can act as a protective layer for the bacteria and viruses, while the disinfectant doesn't need to be wiped down, all surfaces MUST be wiped down prior to spraying to adhere correctly. The CDC website mentions wiping down before disinfecting, that's why at Andori Cleaning Solutions we make sure to remove dirt and impurities from surfaces before proceeding to disinfect using EPA-registered disinfectants as recommended by the CDC.
