I got to say distilled vinegar its the best to get rid of mildew and odors. I'd try 1 cup of HOT vinegar, cook in the microwave or heat up on the stove until it boils and pour into a full load of hot water and run through a cycle with a white small towel, the towel grabs whatever junk is sitting on the inside. I use vinegar in our loads my husbands a chef and his clothes sometimes can really stink up the machine from combintion of food and sweat. You might want to open a window when you heat up the vinegar. Good Luck!
