I started out using Charlie's soap on just diapers and tide (whatever one had a good scent at the time) on the rest of my laundry. With Charlie's soap that defeats the alleged purpose (build up on washer supposedly). I currently use Charlie's soap on all my laundry. I find it works best across all my laundry and it was just by chance. Love that stuff. I don't think it matters too much, but I'd definitely leave out fabric softener!
