1/4 cup baking soda
1/4 cup water
Start by mixing together the baking soda and water in a small bowl. This is going to be the detergent for cleaning the washing machine. Pour the vinegar into a measuring cup and head over to your washing machine.
Add the baking soda mixture to the detergent container of your machine and pour the vinegar into the drum. Set your washer to normal load at the hottest water setting. Close the door and start the machine, letting it do all the hard work for you. The baking soda and vinegar naturally break up mineral deposits and any mold growth while cleaning and refreshing your washing machine.
Use a clean scrubber to rub around the opening of the washing machine, removing stubborn mold or residue. Wipe clean with fresh water.
