Whether your piece is made of fabric or leather you should dust or vacuum your furniture weekly and remove any dirt before either becomes embedded into the furniture.
FABRIC – After you’ve chosen your fabric be sure to check its cleaning code. This informs you of the best method for cleaning that specific fabric. For example, “W” indicates that a water-based cleaner such as a mild detergent can be used on the fabric, while “S” signifies a water-free cleaning product is best. Always test a small area on a hidden part of the sofa or chair first. When in doubt do not attempt to clean it yourself. Consult a professional upholstery cleaner instead. Fabrics labeled “DC” mean dry clean only and must be cleaned by a professional upholstery cleaner.
LEATHER – With respect to leather in addition to being dusted or vacuumed on a regular basis; any spills and stains can be cleaned with a damp cloth; do not use soap or detergent. You may also apply a mild conditioner to keep the leather supple. And as previously mentioned always test a small area on a hidden part of the sofa or chair first.
