Care & Maintenance

Seat Fabric and Back Mesh
These fabrics are colorfast when using standard wet and dry cleaning processes and are also resistant to most spot-cleaning solvents.

     Dry soils: vacuum surfaces regularly to prevent sand, dust, ash, and dry dirt from being worked into the fabrics.
     Wet soils: use commercially available water-based upholstery detergents to clean mud, spills, food, and so on. Follow directions on package.
     Oily spills: grease, tar, greasy foods, etc. may require cleaning with a solvent cleaner or solvent-fortified detergent. Follow directions on package.

A blotting technique should remove most spots. Avoid brushing or rubbing to prevent pilling of the fabric surface.

Most stains can be removed with lukewarm water and a mild soap. Then wipe the leather with a damp cloth and dry with a soft, dry cloth. Saddle soaps, polish, or wax should never be used. For general maintenance, dust the leather surface just as you would furniture.

Use a mild detergent and warm water; apply with a soft clean cloth. Hard scrubbing with brushes may harm the surface so is not recommended. Remove any soapy residue with clean water and clean cloth.

Clean with lukewarm water and a mild detergent as needed. After washing, rinse with clean water on a soft cloth, and dry with a clean soft cloth.
