What do you think? Do you find it completely disgusting to not use detergent at all? I don't know, I'm kind of curious about it. I think the first few times it would be okay since there is probably some soap residue left on them anyway. I already separate and bleach underwear, because of a different article I read about bacteria living in your washing machine. So that would take care of that concern. Hm....I might try it. At least every OTHER time.
