This Walex Elemonate Grey Water Deodorizer prevents clogging and bad odours with the latest technology in quick-dissolve tablets. Elemonate uses the same odour-control formula found in our Porta-Pak Holding Tank Deodorizer – plus special enzymes designed to deodorize and dissolve grease and break up fat and food particles in grey tanks, garbage disposals, dishwashers, and sinks and shower drain lines. Continued use keeps tanks and lines free-flowing and odour-free.
