However, that liquid poop also stains like you can't believe! Okay, some will tell me, "who cares, it's a diaper". But many other moms like me want nice clean diapers, at least once in a while.
So I am giving you this useful tip on how to bleach your diapers: Wash as usual, no special bleach needed, and just hang them in the sun after. The sun has amazing bleaching and disinfecting properties and will whiten your diapers like magic.
I have tested it with fresh stains and old stains, they all disappeared. I live on the rainy West Coast, and I have even managed to bleach diapers and a poopy outfit in the middle of January pooring rain. It took longer but there still seem to be enough UV rays to get the stain out.
It will also work in freezing temperatures, if you ask your parents, they might have stories about their own parents/grand-parents "drying" their diapers out in the winter. Knowing what I know now, I am guessing my Grand-Mother wasn'st drying them outside. She was smart enough to dry in the house by the fireplace. She was using the bright winter sun for bleaching.
If you find your diapers crunchy after drying outside, I suggest to fluff them in the dryer with a damp towel for a few minutes before folding them and this should soften them.
