Okay, so I will admit, I've never thoroughly cleaned or sterilized my washing machine before, but I recognize that my machine is probably gross as heck! We wash cloth diapers in there as well. We have a top loading washer and I'm always aware of the dirty clothes/diapers that touch the top of the agitator where the water doesn't get to it, and that kinda grosses me out! How do you wash your washing machine? How often? What cleansing solution do you use and what is the water setting you use?
