I've been buying detergent that claims you can wash in cold and get your clothing clean. It seems to work. The downside is that even with that one time a month "Washer Clean" cycle with real bleach, the machine developed a funky smell and ick in the drain tubing. Of course, except for when I am running the machine, the door remains open, and I never, ever let wet clothing sit in the washer. I tried everything to clean it. Eventually I saw something on line, and we all know if it is on-line, it must be true. Ha ha But this worked well for my stainless interior washer. I used dishwasher detergent and the hottest setting. I had to do this a few times, but it is all better now.
