Sport Suds Washing Machine Cleaner loosens soap scum, foreign debris and other growth and washes them away. It's unique fragrance-free formulation cleans effectively and removes odour causing materials at their source without the need to resort to perfume to mask remaining odours. Suitable for both top-loading washers and front-loading HE washers. To use, empty the contents of one pouch in the detergent drawer or directly in the washer's drum and run the washer on its longest cycle using hot water. Follow immediately with a 'rinse only' cycle using cold water with no detergent or other cleaning products. Use Sport Suds Washing Machine Cleaner once a month. Machines with significant deposits or extensive odour may require multiple initial and more frequent treatments. Package includes five pouches.
