I can't fit my doona in my machine.
The kids I wash in it with wool wash on the wool cycle and hang in the sun, but the King is too big and heavy.
If it needs a real wash it goes to the dry cleaners.
If I'm desperate it either goes into the bath with just warm water and wool wash and I let the kids stomp it, then I wring out as best I can and hang somewhere sturdy and hose it, or I spot clean with wool wash, hang it somewhere sturdy and hose it.
