I haven't used that one but I use Hobbs 80/20 fusible batt. The package says to wash with a mild soap and agitate manually for 15 minutes in the washing machine. I washed my quilts in my top load washing machine alone with colour catchers and lots of water. I do a short 5 minute cycle (I let the machine agitate I don't do it by hand)and let it spin, then into the dryer.
