4. Mild Humidity Control
Salt is hygroscopic, meaning it attracts and absorbs water. In damp environments, the lemon-salt combo can reduce slight excess moisture in the air—helping to prevent mold or that “damp smell” in tight spaces.
How Long Does It Last?
A salted lemon will stay effective for about 2–3 days before drying out. After that, toss it and make a fresh one. It’s eco-friendly, compostable, and incredibly inexpensive to replace.
Bonus Tip: Clean With It!
Before discarding the lemon, don’t waste it—use it to clean your sink or cutting board. The salt acts as a gentle abrasive, and the lemon’s acidity helps disinfect. Just rub it over the surface, let it sit for a few minutes, and rinse with warm water.
