The summers dust and sun ruined my new window fixtures, being white i couldn't remove it on my own, i took them to a local cleaner who wanted $75 to clean them, at Blind Shiners they gave me a beatable price for $40, when i picked up the pieces of articles i had from the windows all the dirty texture look was gone, and they had gotten the window coverings crisp white i was amazed and have since referred all of my friends to their service
