Baking soda is known for being a powerful cleaner, degreaser, and odor neutralizer. It will not only help get rid of the dirt on your dishes, but will also keep your machine from smelling funky. Sodium percarbonate, or washing soda, is a kind of oxygen bleach, and it’s the active ingredient in products such as OxyBoost. It cleans, disinfects, and it’s highly soluble in water, which means it’s also environmentally friendly. Citric acid is also a powerful cleaner and, by itself, will do a great job disinfecting your washing machine, your dishwasher, and even your electric kettle. Finally, salt—if you choose to use it—will help get rid of the lime in hard water. Adding it to your tablets will help keep the tubes in your machine clean and clog-free.
