I spritz the batting with water from an old windex bottle that became my spritzer. Very lightly and then I put 4 wet wash clothes and my 6 woolie balls and put it all in the dryer on low. Run it for 10 minutes, open the dryer, shake out the batting and throw everything back in the dryer for another 10 minutes at low and then take the batting out and lay it out or hang it on my clothesline in the garage. It works for me because I always wash all my fabrics before I quilt them and then every thing has been dried including the batting, the backing and the fabric. My choice.
