Remember to ventilate rooms when you clean with ammonia and dilute it as recommended on the label. Never mix ammonia with bleach. Keep chemical cleaners out of reach of children to prevent exposure and poisoning. Ammonia can also be released into the household air when pets urinate on rugs and when litter boxes are not changed often enough. Ammonium chloride is the product from the reaction of hydrochloric acid and ammonia. Ammonium chloride is obtained as a by-product in different chemical processes, particularly from the Solvay process for production of sodium carbonate from sodium chloride, ammonia, carbon dioxide and water.
