good advice Im sure!
Its surprising what a spray bottle with warm water,and just a few drops of dish wash detergent, a warm damp rag,and a soft tooth brush, followed by paper towels will sometimes remove
"(Polyvinyl Chloride Plastic)
Vinyl - Polyvinyl chloride - PVC - is thermoplastic. It may be made in a film and bags used for food wrap and micro-waving, or molded in a rigid form in containers. It is made into refrigerator gaskets, used to coat fabric for upholstery and to coat wallpaper for washability, and in making floor tile, horizontal and vertical blinds, countertops, window screens, and other items. It is used in dishwashers for lining the inside and coating the wire racks. It is not affected by most chemicals. It is strong, resists weathering and most chemicals, and may be transparent, as film.
It may have an odor when boxed so needs airing before use. Also may have an odor if not dried thoroughly before storing. Do not use moth repellents with it as they harm it. Do not put on lacquered surfaces as it may stick. It withstands moderate heat but do not expose to too much heat.
Vinyl Upholstery
Regular Cleaning
Vinyl upholstery fabrics are produced porous to allow perspiration venting and will absorb stains. Wash with mild detergent and water. Use a soft bristle brush for stubborn soil. Rinse and dry. Some household cleaners and solvents remove plasticizers from vinyl, making them brittle. Abrasive cleaners scratch the smooth surface. Sometime letting detergent solution stand on surface and "soak" a few minutes loosens soil."
