Biowashball is a unique product designed to clean clothes without the use of harmful detergents. In fact Biowashball is a detergent replacement. Just place biowashball in any washing machine run on cold or hot cycle and clothes come out clean. Biowashball also reduces the risks of allergic reactions linked to the use of detergent, eliminates germs, saves money and is not harmful to the environment. Unique ceramics in Biowashball make this cleaning technology possible. During the wash cycle the combination of the ceramics and the water alters the PH in the water. In turn this specific PH creates an environment in which dirt can no longer stick to clothing. It actually changes the adherence properties of the dirt. During your rinse cycle, the dirty water is drawn out of the machine and you are left with clean clothes.
