Musty smells

[minniemoo]

Hi, I bought some curtain material and had it stored in a plastic bag in a spare room. Our central heating boiler was faulty and the condensation was dripping onto the bag although I've checked the material and that doesn't have any stains on it so I don't think it got wet. My husband put the bag into the loft about 2 months ago and when I got it down tonight all the material has a really bad musty smell. I want to use the material and wonder how I can get rid of the smell. I can't wash the material as it is a very delicate muslin and will probably ruin it before I have even used it. Does anyone have any ideas of how I can get rid of the smell? Thanks.

Wash it by hand in lukewarm water and hang outside on washing line to dry. That will get rid of most smells.

Thanks Figi, I think that's the only answer.
