The O-Cedar Dual-Action Duster Set features a fluffy microfiber duster for dry dusting and a dual-sided, flexible chenille and microfiber duster for deep cleaning. Our microfiber duster heads clean better than cotton dusting cloths, as microfiber uses millions of microscopic fibers that attract and lock-in dirt, dust and moisture. Use as a hand duster or extend to dust cobwebs in hard-to-reach places, such as ceiling fan blades, tall ceilings, high window sills, shelves, and more! Our hand duster is designed with a extendable handle that measures 24" to 49" long. The bendable chenille and microfiber duster can be used for deep cleaning and works dry or damp. This duster is also reusable and machine washable up to 50 washes. Replace every 60-90 days for optimal dusting and cleaning results.
