Due to popular demand, Wildlife Research Center now offers a line of Scent Killer detergents formulated specifically for front loading or high-efficiency washing machines. According to one washing machine manufacturer, "30 percent of washing machines sold today are high efficiency." And, if you own one of these machines, you already know that using any detergent other than those rated for high-efficiency washers can damage your machine. Included in the new line are Scent Killer Powder Clothing Wash™, Liquid Clothing Wash™, Autumn Form-ula® Liquid Clothing Wash™, and Carbo Wash® for carbon clothing.
