I always do a long cold wash with detergent and baking soda and a second rinse first, then a long hot wash with a second rinse, no detergent. Always after the first cold wash and rinse my diapers still stink. Ick! ...but after the hot wash they smell all fresh and clean, actually...they don't smell. :LOL That's a good thing. <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/orngbiggrin.gif" style="border:0px solid;" title="orange big grin"> Dh did a load of diapers for me last week (<img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/love.gif" style="border:0px solid;" title="love">) and he said later, "ummmm...are the diapers supposed to still smell after the cold wash?" I said, "yep". <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/sick.gif" style="border:0px solid;" title="sick">
