Our disinfectant of choice is Vital Oxide, a no-rinse sanitizer with a category IV toxicity rating, making it safe for food-contact surfaces like countertops and cutting boards. The active ingredient in Vital Oxide is chlorine dioxide (CLO2), a compound introduced in the 1940s to disinfect drinking water. Vital Oxide falls into the category IV toxicity rating, making it a no-rinse sanitizer for food-contact surfaces like countertops and cutting boards. I recommend easily available products like Vital Oxide that stress low-to-zero toxicity. Once your work area is fully sanitized, allow everything to dry for about an hour.
