If its just a few diapers. I strip them in the sink. Squirt some Dawn on each one, use a toothbrush or just rub the fabric against itself to kind of scrub the dipe. I let it soak in really hot water for a bit then rinse it well.
And I always bleach used diapers. If you're going to do a full load and just bleach everything, about 1/4 cup is good.
