Long story short, day care was covering DD in BB's diaper cream with every change (for no particular reason, I might add). Now the insides of her HHs look crusty and incredibly gross despite several washings and me taking the diaper cream away from day care. I know this has been discussed before, but I forget the advice....how do I get this gunk out of my dipes? I'm afraid to use anything too harsh for fear of ruining the PUL. I've already tried Sport Wash. Any thoughts?
