Wait, does baking soda actually help with the odor or is it more for the seals? I tried it once on my old GE and ended up with white powder caked in every crevice for weeks. My sister swears by vinegar rinses instead, but I'm scared to try that on my new unit. Last year I used a store-bought cleaner that promised no residue and it just made everything sticky. Now I just wipe down the drum with a damp cloth after every load and hope for the best. It's not scientific but it keeps the musty smell away better than anything else I've tried.
