This video shows how to clean a stained washing machine. Stains are typically caused by brown dirty water in the washing machine. Water is usually brown because it contains high levels of iron. The narrator demonstrates a product called CLR, which can be purchased at Home Depot. It is a product designed to remove iron and lime. He shows how to apply a small amount of the product with a sponge to the inside tub of the machine. He advises to let it soak for about 5 minutes. He then wipes the inside of the tub with a scrub sponge. The next step is to run the machine through a wash cycle to remove any remaining product before washing clothes.
