While you are fiddling with the curtains in trying to get them down, make sure you put something underneath the curtain and on the ledge where the top and bottom of the Hi-Lo meet. Some of the staples will just fall out, and if you don't have something to catch them, they end up in the crack between the top and bottom parts of the Hi-Lo body. We haven't had to deal with cleaning the cornices or curtains yet, but we have found staples on the ledge after we have raised the Hi-Lo. I guess towing on slightly rough roads might have jarred them loose. Some people we have spoken with in campgrounds who have purchased their campers used indicated that they had an upholstery cleaning service come out to their home and do a thorough cleaning of sofa, cushions, mattress, cornices, and curtains. I assume this is some type of dry cleaning and could be expensive. There certainly must be some type of do-it-yourself dry cleaning without taking the cornices and curtains down from the windows.
