Fabric upholstery:Vacuum and not very soft brush. In case of heavy soiling, chemically clean in dry foam. Remove grease and oil stains with clean gasoline or stain remover. The cleanser should not be applied directly to the fabric, as this leaves marks on the edges. Treat the stain in circular motions from outside to inside. Other contaminants are removed with warm soapy water. Severe dirt is removed by dry cleaning.
