Despite my best efforts to keep the washer door open for it to dry between loads and avoid getting that musty smell, my washer was developing an odor. I considered buying one of those expensive options from the store. Then I found the following:

1. Pour 2 cups vinegar into the machine
2. Run it for 3 minutes on hot
3. Stop the machine (pause the load)
4. Let it sit overnight
5. The next morning, resume the cycle
6. Run a rinse cycle on cold

I do this process on the first of the month.
