Laundry question. I didn't realize that some juice or something spilled in my diaper bag and got some clothes wet. When I cleaned out the bag to switch clothes out I found them and they are covered in mold. I've tried soaking them in biz, washing them and spot treating them. Nothing is working. My babysitter is only one who really uses the diaper bag that's why I didn't notice. It wasn't more then a week the clothes where in there. How do you get mold off clothes? This is just one of the items.
