The dish rack and dishwasher
For slightly different reasons, the place where your dishes go after you've used them should get a bit more of your cleaning attention. Drying racks will absolutely develop mold and mildew because of their constant exposure to water. That means you're ostensibly clean plates, bowls, cutlery, and drinkware are going back in the cabinets with bacteria on them that you probably don't want in your mouth.
The dishwasher, in contrast, is likely to suffer from food particle build-up, as well as from mold or mildew. Both things can be treated with either white vinegar or bleach, easy peasy.
