Bob is cleaning his dishwasher with white vinegar by putting a bowl of this mixture in the top of an empty dishwasher and running a cycle.

Baking Soda

A mixture of white vinegar and baking soda in a bowl will produce a paste that is helpful in removing stains and sanitizing a dishwasher. To meticulously clean your dishwasher, spread the mixture onto the build-up crust in the bottom basin of the washer itself then let it sit for 15-20 minutes before running a short cycle using the hottest water. The baking soda will further absorb the unpleasant odors and will leave your dishwasher smell fresh.
