When renovating a home, you should use a damp sponge or cloth to clean dust collected on a window sill, as the dust may contain asbestos or lead-based paint. Home maintenance is an ongoing process for any homeowner, and here we see an African- American woman who’d taken a damp sponge to her window’s frame, in order to remove accumulated dust particulates. Note how the homeowner had donned a pair of waterproof gloves, a facemask, and a pair of goggles, prior to beginning this task.
