Four winns V Series Owner's Manual page 171

Clear vinyl curtains and windows demand extra care
to prevent scratching. Hose clean water onto vinyl to
rinse off salt, dirt, or grime prior to using a soft, clean
cloth. Dirt or grit in the cloth will scratch the vinyl
window. Be sure to rinse cloth often.
NOTICE
DO NOT use hot water. DO NOT dry in an
auto matic dryer. DO NOT dry clean or steam
press.
Leakage after cleaning may be the result of insuffi-
cient rinsing. Re-rinse. If leakage continues, apply a
coat of silicone air drying water repellent, such as
Scotchguard™. See your Four Winns dealer for
addition al informa tion on weather covers.
