The dark, damp environment under the sink is a breeding ground for germs and bacteria. Dishcloths, sponges, and kitchen towels—whether new or used—should never be kept there. Their absorbent materials quickly become contaminated. Only unopened, factory-sealed packs of sponges or cloths are safe to store in this spot.
4. Dishwasher Tablets and Detergents
It’s common to place cleaning products under the sink since the dishwasher is nearby. While unopened packages are fine, opened ones degrade quickly due to humidity. There’s also a safety concern: children or pets can easily reach them, creating a dangerous situation.
5. Potatoes, Onions, and Other Foods
Humidity is also the reason food items don’t belong here. Vegetables like potatoes and onions, or pantry staples such as flour and salt, spoil quickly in this environment. While they need darkness, they also require a cool, dry place—such as a cellar or a cupboard away from heat and moisture.
