Cleaning most window coverings, like blinds, draperies, shutters, or shades, can be done with a duster and a washcloth. Routine dusting will prevent the accumulation of filth, but wiping them down with a damp cloth can make them sparkle again. Ultimately, it all depends on the material, though. A washcloth doesn’t do much good on draperies, and certain types of wood blinds or shutters may require special treatment.
