Is your washer an HE front loader? Affresh will remove and prevent the build-up of odor causing residues in all brands of HE Washers. Bleach only kills the odor causing bacteria, while Affresh washer cleaner removes the root cause of bad odors. Using surfactant chemistry, Affresh is a slow dissolving, foaming tablet that gets underneath built-up residues, breaks it down into small particles, and then washes the residues away. This product will leave your washer and clothes clean and smelling fresh.
