Our dark colored clothes are coming out of the laundry with wet or oily looking small, round stains. We do not wash oily clothes or rags -- either shop grease or kitchen grease. This does not happen to our light colored loads. You cannot see the stains while they are on wet clothes, so they are set in by the dryer before we can see them. We have a used Maytag Neptunefront-loading washing machine and dryer. This has been happening for the several months we have had it.
We have run several empty loads: some with hot water and bleach, some with hot water and baking soda, with vinegar in the softener dispenser. We use Sun "free&clear" environmentally friendly detergent "safe for HE machines" and cut down to using 1-2 tbs instead of the full recommended amount. Then we added about an equal amount of dish liquid to the detergent and cut the amount we use down to 1 tbs. We have tried large and small amounts of OxiClean in each load. We have always used vinegar instead of fabric softener. Nothing seems to prevent the oily stains showing up when we wash colored clothes in cold water. I'm stumped!
