Vintage Trimmings

I've been given a couple of boxes of vintage trims from my mother in law today to sell and am not sure what to do with them. I feel they need to be cleaned but how do I do it without ruining them? She's also given us a box of sewing stuff and a great box of buttons. It was lovely looking through them, some are from her old school cardi, a winter coat she had when she was little and best of all a tiny pink enamelled button from one of her first baby shoes! If anyone is interested in them or has ideas about cleaning them please get in touch. Happy Mothers Day to all the hard working mums out there.
