It sounds like a strange kitchen experiment, but placing a simple bowl of salt in your refrigerator is one of the most effective, “old-school” hacks for a cleaner, fresher home. Before expensive deodorizers and high-tech air filters existed, this was the go-to secret for keeping a kitchen running perfectly.
Once you see what it does for your food and your energy bill, you’ll never want to have an “empty” shelf again!
What Happens When You Add Salt?
- Eliminates Stubborn Odors: Salt is naturally hygroscopic, meaning it attracts and absorbs molecules from the air. Instead of just masking smells (like a spray does), salt actually pulls the odors into itself, leaving your fridge smelling like… well, nothing!
- Moisture Control: Excess humidity is the enemy of fresh produce. Salt helps absorb the extra moisture in the air that causes your cucumbers to get “mushy” and your berries to grow mold. It acts like a natural dehumidifier for your crisper drawer.
- Frost Prevention: In older fridges, excess moisture leads to ice buildup on the back wall. By reducing the humidity, salt can actually help prevent that annoying frost from forming, which keeps your fridge running more efficiently.
- Keeps Milk Fresher: Because it stabilizes the environment and reduces the growth of moisture-loving bacteria, many people find their dairy products stay fresh right up until their expiration date.
How to Do the “Salt Hack” Correctly
You don’t need fancy sea salt for this; the cheapest table salt works perfectly!
- The Container: Find a small, open bowl or a shallow jar.
- The Amount: Fill it with about ½ cup of salt.
- The Placement: Place it toward the back of the middle shelf. This is usually where the airflow circulates the most.
- The Refresh: Every 2 to 3 weeks, you’ll notice the salt might look a bit clumped or damp. That means it’s working! Toss it out and replace it with fresh salt.
Pro Tip: For an extra boost of freshness, mix a few drops of lemon juice or a piece of dried lemon peel into the salt. It will act as a natural, subtle air freshener every time you open the door.
A Cleaner Fridge for Pennies
