The Damp Duster collects and traps dust in one quick wipe! Under running water, it rinses clean, so you can use it time and time again. Perfect for blinds, vents, baseboard, railings, mirrors and more. Product arrives pre-moistened in packaging. Dampen with water before each use to soften foam. Just re wet it before each use to soften the foam. No, or minimal, chemical quality cleaning. Dust remover, simply wipe off the dust and debris. When you wipe, use a corrugated sponge to fix the dust on it, instead of letting the dust fly away with the wind.
