To get diapers clean you need 5 factors. These factors include WATER, ACTION (agitation), TIME, CHEMICALS (detergent), and HEAT. In and ideal situation all of these factors would be equally balanced and laundry would be easy as pie (chart). Sorry for the pun-ny. An HE machine cuts down on your water component, and if you are as lucky as I am to live in an area with hard water, this will further complicate your wash routine... fear not!
