Carpets warm a home by adding color, pattern, and texture. Regular vacuuming provides the first line of defense against dirt and grit that damages carpet fibers. But carpets also need regular cleaning to keep them looking their best. Plan to thoroughly clean your carpets every 12 to 18 months, more often in high-traffic areas. If you have light-color carpet and/or kids or pets, clean your carpets two or three times a year. Always follow the carpet manufacturer’s cleaning guidelines.
