You don't actually wash it, you fill up the washer with cold water and don't let the machine agitate.
Push the batting up and down with your hands for about 5 minutes, then let the washer spin the water out and put it in the dryer for about 15 minutes.
Certain types of cotton batting will disintegrate in the water. These are the old-time vintage cotton battings (such as Mountain Mist 100% cotton) that are not needlepunched or bonded. I'm pretty sure these battings have a "do not prewash" instruction on the package. Typically these are battings that specify quilting lines no more than 2" or so apart.
