I know nothing about cleaning these types of things, but I have a hand-crocheted quilt that was made by my great grandmother. It's covered in dust/dirt and I'm sure mouse pee/turds all over it. (I've been attempting to clean out my brother's house of any memories/valuables.)Is there anything I can do to clean it? Other than the bathtub, I have nothing bigger to hand clean it in. Can I put it on a gentle cycle in the washing machine? I'm afraid the dryer would ruin the fiber. Will the color (mostly white with sage green "rosettes") be ruined when I wash it? Do I lay it out to dry or can I hang it over the shower rod to let it dry?
