Vinegar is one of the most versatile liquids in existence—aside from water, that is. This acidic concoction can be used for cooking, killing weeds, and, yes, cleaning. When you combine vinegar with the equally-versatile substance known as baking soda, you've got cleaning gold.
Making your dishwasher smell fresher than ever is a simple task. Just take out your dishwasher's filter and soak it in soapy water for about 10 minutes. Once you replace it, toss one cup of white vinegar on the bottom of the dishwasher and use the heavy cleaning cycle.
