We have a 2011 22' Sport Bambi front bedroom trailer. The curtains on tracks top and bottom cover the curved front corner windows and the front window. They require cleaning as one of them is soiled. They are white with a fabric on one side and stiffer opaque fabric on the other that holds the guides that fit on the tracks. I can't find any cleaning instructions in the information I have. Our inclination is to wash them in cold water and hang them to dry but would appreciate any information anyone has on these curtains.
