I live in Los Angeles where the bar soap for clothes washing is generally made in Mexico. Zote is the big name. I am totally not into hand washing. I pretreat my white scrubs and undergarments. I like to use hot water that would be extremely unfriendly to my hands. I have known people in Arizona who use laundry water for the garden (non vegetable).
