This always used to happen with our Bumkins AIOs, but not any other diaper. The only thing that worked to get rid of it was hanging them in the sun. I've never been able to figure out what caused it though.
Actually its more orangy. Its like that in all the ones that have a good amount of pee after about a day in the pail. The Under the Niles, the old gerber prefolds, the new prefolds from Green Mountain Diapers. I don't know if the detergent I use is leaving residue and the pee reacting? I thought RLR was good enought to strip them of anything?
The color does wash off, and I make sure they spend a good amount of time in the sun, I just don't know what it is, or something I should look into.
I'm going to start doing extra rinses since the washer is old it might not be getting it all out..?
If it is orange it is Uric acid crystals and normal in newborns, but could signal dehydration.
You might want to google it and see if you can find a pic or more info.
My DS had it and it went away fairly quickly.
I used to get pink stains on my kushies and Bummi whisper pull on covers (but not the wraps) bright hot pink. Never figured it out but one day found a forgotten bottle of pumped breastmilk in my car all old and icky but the "milk" had turned the same hot pink. : DH said cause it was girly milk :
Don't think its dehydration she pees every hour
I think it is deposits from the detergent. I have an old washer and tried doing a second and third rinse showed me suds still!
and I stated it wrong, at closer examination it is an orangy color, it shows up after it starts to dry. hopefully the extra rinses help. We are moving so the washer is going in the trash
This happened to my son's diapers and inserts, except ours turned purple. We thought it was mold but sometimes the diapers at the bottom of the pail would be white and the ones at the top of the same pail would be purplish. I finally pinned it down to baby tylenol. On the particularly bad teething days (the days that I used tylenol) the diapers would turn purple as they sat in the pail.
