Vertical Blinds: Vacuum carefully with the brush attachment used for draperies, or clean with a lamb's-wool duster. If fabric-covered, spot-clean only; don't use soap and water.
Wood Blinds: Dust with vacuum or lamb's-wool duster. For occasional deep cleaning, use a wood cleaner such as oil soap. Do not use soap and water on wood blinds.
Wood Shutters: Dust natural wood shutters. If painted, wash in place. Cover the floor and sill with plastic or a drop cloth. Use a brush dipped in detergent and water. Rinse and dry with a cotton cloth.
