I put it in the washer and soak it with reg soap powder, than put it on spin. Fill up the washer with 1 cup of vinegar and let it soak again, than spin. Vinegar sets the color and delutes the suds and doesn't put wear and tear on the quilt. Watch your water color and you will know if it is clean. Soak time is about 30minutes or if I am busy it is when I remember. Never had a problem. 10-20 minutes in the dryer and layed out after to dry.
