I would wash it very gently with Orvus soap and a color catcher or two. Then I'd tumble it in the dryer before laying it out flat on some towels. I wouldn't take it to the fry cleaners as their chemicals never come out.
After my MIL passed away, I took a quilt that I'd made her to the cleaners and insisted that they wash and dry it without using any dry cleaning chemicals. Well, when I got it back it stunk! They completely ignored my instructions. I've never been able to use it since.
