Unger's Screen Cleaner can easily scrub and clean dirt and pollen from window screens, siding, and outdoor furniture. The brush side loosens the dirt, while the scrubber side washes tough dirt and grime from the screen. For cleaning high windows, attach the screen cleaner to Unger's Professional Dual End Aluminum Pole (sold separately). The Microfiber sleeve is machine washable for easy cleaning. Unger guarantees to replace any Unger Professional branded product found defective in material, construction, or workmanship.
