Why is chlorine bleach recommend for sanitizing hard surfaces?

Rating: 92

One tablespoon of chlorine bleach in a gallon of water meets the United States Public Health Service's recommended levels of hard surface sanitation. Chlorine bleach specifies that one tablespoon of chlorine bleach in a gallon of water is equivalent to 200 ppm available chlorine. Use this to sanitize food contact surfaces, food equipment, and refrigerators and freezers. The USPHS recommends a ratio of 1/4 cup chlorine bleach to 5 gallons of water for a final dip for pots, pans, glasses, dishes and utensils.
