Multi-purpose sanitizing tablets, used for sanitizing food contact surfaces. One tablet used per one gallon of water. 150 tablets per bottle. Simply use 1 tablet per gallon of water to accurately and easily prepare your sanitizing solutions at the proper concentration required by Health Department Regulations. Tablets dissolve in water producing a distinct, clear, pale blue sanitizing solution which tells operators and inspectors at a glance that this sanitizer is in the final rinse sink. Sanitizing solutions are non-irritating to the hands, non-corrosive to metals, non-staining and odorless.
