Dusty houseplant leaves? Clean gently, according to leaf type
University of Minnesota Extension says leaf dust can block light. Wipe large, smooth leaves with a damp cloth and rinse sturdy plants gently; leaf-shine sprays are unnecessary.
Indoor plants collect dust just as furniture does. A damp cloth suits many broad smooth leaves, but fuzzy or fragile leaves may react poorly to wet wiping. Identify the plant and check its care requirements first.
