Refresh your sofas and chairs with a yearly scrubbing. Search the supermarket for steam cleaners or spray bottles with a brush attachment; they'll help to gently lift dirt from the upholstery. Before you use a new cleanser, first test it in an inconspicuous spot. If the fabric's color and texture looks good once the cleanser has dried, you'll know its safe to use on the remainder of the surface. When cleaning, pay special attention to areas where hands and heads tend to rest—those are the places that need the most elbow grease.
