First, thanks to the regulars - you have helped me immensely! Now, for the problem: My wife and I have a 1958 ranch home on Long Island. The living room has a bay window facing south. It is a 5-panel Anderson, approx. 5.5' tall by 7' wide total size. Only the end panels open and close with cranks (casement style). We recently had a decorator install full-length curtains in the window on a curved rod that follows the window shape. They are made of cotton & linen, and are 'semi-sheer' - you can see shadows/light through them, but that's about it. We had them installed in early summer, and recently noticed mildew/mold spots on the curtains. We were able to have them cleaned, but they are delicate, and we're not sure they would do well after repeated cleanings. I am assuming that the problem is that the condensation that we occassionally get on the inside of the panels that open is adding moisture to the curtains. Is there a way to prevent this? Is there anything we can treat the curtains with to prevent the grwoth of the mildew/mold? The decorator hasn't made any recommendations, and neither has the cleaner. Any suggestions would be greatly appreciated.
