Split-blended HYGEN microfiber dust mops trap and lock away dust and dirt on floors. Fringed construction to help remove dust and prevent the spread of infection. Durable for up to 500 launderings (up to 200 with bleach). Bleach-safe in hot or cold water. Fringed edge increases surface area for faster cleaning. Double finished edges retain mop shape with use over time. Fringed Microfiber Dust pad grabs and holds larger dust particles and debris, providing 50% more surface area than non-fringed pads.
