Hi, I have had a couple loads of laundry ruined due to dark blotches that have appeared out of no where on my clothes. They are not bleach spots. I don't wash with bleach. I keep like colors together. I don't wash rags that have cleaning fluid (like dust spray) with my clothes. Is is something with my washer? Please help. At this point, it's safer to have my clothes professionally laundered, though I hate to fork out the cost for it. Thank you!
