My dipes are starting to smell a little "off." They don't really stink and it's not an ammonia problem....they just have an odd smell. When I stop and think about it, I guess I could say that I started noticing it since she started solids and her poop changed. I do use a diaper sprayer for poops. Any idea on what the problem might be? Not enough detergent? Some kind of buildup? I have a top loading machine and I do a cold rinse, hot wash with Ruby Moon detergent, usually just a single rinse, but sometimes add an extra rinse, line dry when I can.
