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.
