1. Fill the washer using the highest load size and hottest water setting.
2. Add a quart of vinegar and allow the washer to agitate for about a minute. After a minute, open the lid and let it sit for an hour.
3. When the cycle is done, start again. This time add a cup of baking soda. Don't forget to use the hottest water setting.
4. You're all done!
I bet your laundry machine will be smelling so fresh after this! You can also use the time between cycles to clean the exterior and knocks and crannies under the lid.
Good Luck!
