The batting manufacturers don't recommend doing that because they say it might make the batting come apart. They recommend soaking it in a large sink or bath tub, then draining it, pressing the water out of the batting and then laying the batting on a flat surface to dry.
Occasionally I get some pulls in the batting using my process, but can usually push them back together and even baste them, if necessary. But most of the time, it comes out fine.
Happy Quilting!
