You can also fill up your bathtub with warm water and mild soap and soak and agitate the quilt by hand. But it’s hard to get all the soap out afterwards.
A modern quilt should be fine in your washing machine on a gentle cycle. Just be sure to inspect it first and repair anything that is coming apart.
Did you say it was machine quilted? Should be fine.
It is machine made. I think I’ll try it in the machine on the gentle cycle using mild soap.
I wnat to put it in the dryer, at least for a short time.
