The water should be hot enough to increase the activity of the solution, but not so hot that it increases the evaporation of the disinfectant. Generally, temperatures between 75°F and 120°F allow disinfectants to work properly. At higher temperatures, chlorine compounds can corrode certain metallic elements.
