Chlorine sanitizing solutions should be at a minimum temperature of 75Â°F. They are less effective at lower temperatures. At temperatures higher than 120Â°F chlorine may evaporate from the solution and corrode certain metals. In general all sanitizers work best at temperatures between 75Â° and 120Â°F.
The concentration of the sanitizing solution is a critical factor. In the case of chlorine bleach, the 1997 FDA Model Food Code recommends a concentration of 25-100 ppm (parts per million) depending on the job to be done, the temperature of the water and the pH of the solution.
