The sink cabinet is a very easy place to store a multitude of items you don’t know where to put.

However, there are some categories of objects (and foods) you should never store in that space because of the fact that they would end up spoiled: here’s what they are and why you should never leave them under the sink.

Let’s find out together.

1. Paper and Cardboard

Even the most well-maintained sink can have small leaks that make the area underneath very humid. Therefore, the first items you should never store in the cabinet underneath are anything made of paper and cardboard: napkins, boxes, bags, and paper towels are all at risk, because the humidity not just softens the paper, but could ruin anything stored inside boxes and bags.

2. Small Appliances

For the same reason, you are not advised to store small appliances or any other electrical or rust-prone device under the sink: water and humidity are appliances’ worst enemies, which can short circuit and break. The safest way to store hand blenders, food processors, blenders, and other small appliances is in a dry cabinet, preferably in their original packaging. Additionally, be careful with rust-prone items or items made of highly absorbent materials that will come into contact with food, as humidity could deteriorate them, forcing you to throw them away.

3. Dishcloths and Sponges

If you have a kitchen towel, dishcloth, sponge, or any type of cloth, whether new or used, you should never store it under the sink because this damp, dark, and closed place is ideal for the proliferation of germs and bacteria. These types of objects, precisely due to their highly absorbent composition, would quickly become contaminated, and using them would be dangerous (for this reason, you must always remember to sanitize them thoroughly). Only sponges and dishcloths that are still sealed in their packaging and have never been opened or used can be left in the sink cabinet.

4. Dishwasher Tablets and Detergents

Storing detergent and dishwasher tablets in the cabinet under the sink is a natural progression, because this appliance is located right next to the sink in most kitchens. Be careful: it’s fine in case they’re new and unopened, but if they’re already opened, they’ll deteriorate quickly because of the humidity in the room. In addition, if you have children or pets at home, these products may be at their height and dangerously easy to access.

5. Potatoes, Onions and Other Foods

The problem is always humidity: products like potatoes and onions, flour, and even salt are very sensitive to humidity, and while they certainly need a dark place, they also need to be away from heat and humidity. Stored under the sink, they would quickly rot; it’s best to store them in a cellar or, failing that, a cupboard away from light, heat, and humidity.
