Remove all loose cushions. Loosen dirt with a hand-held dusting brush while using a vacuum brush attachment to remove dust. Vacuum all surfaces of the furniture: back, sides, arms, skirt (if applicable) and the platform beneath the cushions. Vacuum both sides of the loose cushions.
When necessary, you can use commercially available cleaners on Theodore Alexander upholstery. Be sure to test on an inconspicuous area first. For day-to-day cleaning use a soft, clean, damp cloth.
