Guidelines for the use of 3.2g ECT for glassware, mops and cloths:  After cleaning mops or cloths, dissolve 1 tablet in the recommended amount of water to produce 100 ppm of available chlorine.  Immerse the cloth or mop in the solution for at least 30 minutes. Do not leave overnight.    Guidelines for the use of  3.2g ECT for food preparation surfaces and food processing equipment: Remove loose debris with a clean, loosely-folded cloth. Wash with a hot neutral detergent solution and cloth. An abrasive nylon pad may also be useful. Rinse with hot water and a clean cloth. Drop one 3.2g ECT into the recommended amount of water, preferably warm (40°C) to provide 200 ppm of available chlorine. (Warm water assists the process of disinfection and also speeds up the tablet dissolution time.) Thoroughly wet the cleaned surface with the disinfecting solution by the most suitable means, e.g. trigger spray or disposable cloth. Leave wet for a minimum of 3 minutes. (Providing the surface is thoroughly clean this is sufficient contact time for positive disinfection.) Rinse off with fresh, clean water. Allow to air-dry or use disposable paper towel. IN THE CASE OF DANGEROUS OR ELECTRICAL EQUIPMENT (E.G. SLICING MACHINES), PRELIMINARY SAFETY PROCEDURES AND FINAL SAFETY CHECKS WILL BE REQUIRED, SEVERAL TYPES OF EQUIPMENT WILL NEED PARTIAL OR COMPLETE DISMANTLING TO ENSURE EFFECTIVE CLEANING AND DISINFECTION. WARNING:  TO BE EFFECTIVE, DISINFECTANT SOLUTIONS MUST BE MADE UP FRESH EACH DAY AND BE OF CORRECT CONCENTRATION.

FOGGING:  If you are using tablets to create a HOCl solution, 1 tablet in 1 Litre Water gives 1,000 parts per million available chlorine (HoCl).

TECHNICAL: Hypochlorous acid (HOCl or HClO) is a weak acid that forms when chlorine dissolves in water, and itself partially dissociates, forming hypochlorite, ClO.  HClO and ClO are oxidizers, and the primary disinfection agents of chlorine solutions.
