Washing is still confusing! All the diapers and diaper sites have different washing instructions, what are the brief general instructions?
To get diapers preped, just remember synthetic fibers only need to be washed once. That include all PUL, microterry and poly fleece. Natural fibers need to be washed repeatedly until they are absorbent as tested by a drip test (dribble water on them and see it rapidly absorbed instead of running off the ducks back.) Natural fibers may lint a lot during these washes so keep synthetic fleece away from these washes. Natural fibers include anything hemp or cotton or bamboo. The denser the weave the more washes will be required. Once everything is prepped wash it all together when soiled! Prerinse anything poopy in cold water. Add extra rinses after wash to be sure all detergent residues are removed.
