I did a search for Cleaning Day/night shades and found that there is no easy way to clean them. Most say that they cannot be cleaned, I did find one person that said to use compressed air but I am thinking that would take a lot of cans. Also I found one site that said to put them up at least 3 or 4 times a day so they don't loose the pleats. They said that if you leave them down all the time they will go flat. Boy am I in trouble cause I like mine down all the time.
I use thoes swiffer duster things to dust them off so if any of you come up with a way to clean them I sure would like to know.
