How to Sanitize Your Dishwasher

Step 1 -
Get rid of any odor that may be coming from the plumbing pips your dishwasher shares with the sink. Pour a half of cup of baking soda down each sink drain. Pour cups of vinegar down each drain until all of the baking soda is washed away. After five minutes, run very, very hot water down each of the drains.

Step 2 -
Clean out your garbage disposal. Slice a lemon/lime and put the slices down your disposal drain. Run your disposal with cold water running.

Step 3 -
Pour two cups of vinegar into the dishwasher and let it sit for an hour and then let the dishwasher run through a cycle with the hottest water possible. Repeat the process is that does not clean up all of the build and film. You can use baking soda and bleach instead of vinegar - just sprinkle the baking soda in the bottom of the dishwasher tub, and pour bleach inside the tub as well.

Step 4 - Between washes, pour 1/4 cup of lemon juice into the dishwasher cup and run a short, but complete wash cycle. This will not only deodorize the dishwasher but will also help get rid of any metal build-up.
