Okay so my MIL told me she washes ALL her clothes in cold. I said "what about personal items like underwear, towels, bras and such?" She said "the detergent sanatizes them." I'm sorry but personal items go in hot water for me. Also I only wash clothes in hot or cold no warm. Me and my DH wear a lot of black and jeans so most of our clothes go in the cold. But what do you ladies do? Do you use all the temp washes or just one, maybe two? I still can't get over the fact that my MIL washes all her clothes in cold. I want my undies sanitized in hot water!
