where are these stains coming from?
I have a king sized down comforter, 12 years old, that has always been kept in a comforter cover. So why are there nasty yellow stains all over it on each side? It just grosses me out every time I clean the comforter cover. I'm pretty sure I can wash the stains out in a commercial front loading washer but just haven't found the time to do it. Has anyone else had similar experiences? TIA!
