Soak in water with Restoration dissolved in it, in the washer. Do not agitate at all. Spin that out, fill with rinse water, and shut off the machine to prevent agitation once again. After soaking, spin that out and repeat for another rinse the same way. I would not recommend going to any trouble to quilt a top before determining if the fabric is strong enough not to fall apart afterwards. Dry flat if possible, out of sunlight, or over a clothesline. Never put in the dryer with heat.
