What's the best way to kill/rid blankets (i.e. heavy quilted winter blankets) of mold/mildew without bringing them in the house and laundering them or sending them out? Is there anything I can spray (no bleach as I don't want to discolor them) on them that'll do the trick? I'd like to spray them with whatever, let them dry THEN bring them in and wash them. They're still fairly wet from the rain we had and dragging them through the house isn't an option.
