What you need:
- Vinegar* or Lemon Juice
- Cleaning Cloth
- Small Brush (toothbrush)
2. Pour two cups of lemon juice or vinegar into the tub and run a full cycle on the hottest setting. (If you have a front-loading machine then put the vinegar/lemon juice in the detergent dispenser instead).
3. Scrub the lid/door and all the corners with vinegar using the small brush and/or the cleaning cloth.
You are done!!!
Note: Remember to always leave the door open after you finish a load to allow the washing machine to dry out completely. This is specially important with front-loading machines to prevent mildewing.
*White vinegar is ideal, but you can definitively use cider vinegar if you wish (just keep in mind that it is a bit more expensive). Cider Vinegar is more likely to be organically produced, which is better for the environment.
