We were lucky enough to buy an ex show home that included all furnishings a few years ago. Including two pairs of dry clean only ceiling to floor heavy curtains. I've only been lightly dusting them by using the hoover since we moved in as, not only are they heavy and large curtains, but they have weights sewn in the bottom hems. I can't face taking them down to take to the dry cleaners but they need a clean. I also don't know about the weights. Any ideas or tips?
