1. Refrigerators
Studies show that the vegetable crisper drawer is often one of the dirtiest spots in the kitchen, since moisture and food bits linger. Ironically, that’s where people keep “healthy” produce that can become contaminated. Refrigerator shelves are regularly exposed to raw meat juices, dairy drips, and other organic food items that can breed harmful bacteria over time—making deep cleaning an important part of proper refrigerator care.
