3 Ways to Use a Dishwasher - wikiHow
Before cleaning the tub, use paper towels to remove food scraps, dirt, and debris from the bottom of the dishwasher. Then, set a cup of white vinegar on the top rack of the dishwasher. Make sure the cup you use is dishwasher safe. Run a full cycle with the cup in place. This should clean and deodorize your dishwasher's interior.
