I agree with the previous recommendations.
If you don't have the Jayco 19H owners manual, the following is from the 2006 19H manual:
"FABRIC CARE - JAY FEATHER EXP ONLY
Please use common sense and treat your furniture as you would at home. Remember, your trailer is a small living area, so soiling may occur more frequently and the fabric will probably need more attention than your furniture at home. Please follow these guidelines for cleaning upholstery fabrics on the cushions/bed mats.
Frequent vacuuming with a brush attachment or a light hand brushing will help remove dust, hair, sand and other particles which may dull the look of the fabric and accelerate wear.
Water base cleaners are recommended. If a spill does occur, blot up the spot, but do not rub it in. Solvents are not recommended since they may have an adverse reaction to the specific backing of your upholstery fabric. Do not saturate the area. Clean it in a well ventilated area and avoid products containing toxic materials. Always pre-test a small area before proceeding. Use a professional furniture cleaning service for an overall cleaning.
A reminder: The upholstery fabrics have been manufactured using quality materials. However, if abused, they are not completely resistant to damage.
CAUTION: Do not dry clean the covers of the cushions/bed mats. If the covers are dry cleaned, the vinyl will become hard and crack."
