Household Recipes - Washing Machine Cleaning

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.
