Put a Glass of Salt in Your Car – A Vital Hack Every Driver Should Know
Maintaining a comfortable and well-functioning vehicle doesn’t always require expensive tools or fancy gadgets. Sometimes, the simplest solutions can make the biggest difference. One little-known yet highly effective trick is placing a glass of salt in your car. It may sound unusual, but this cost-effective hack can help combat humidity, prevent foggy windows, and reduce mold growth—making your driving experience safer and more comfortable.
A police officer shared this tip, and it’s something every driver should consider! Let’s explore why this works and how you can easily apply it.
Why Humidity in Your Car Is a Problem
Excess moisture inside a vehicle can lead to multiple issues, including:
🚗 Foggy Windows – Reduced visibility, increasing the risk of accidents.
😷 Mold & Mildew Growth – Can cause musty odors and trigger allergies.
🛋️ Interior Damage – Moisture can deteriorate upholstery and even damage electronics.
Humidity builds up from wet weather, leaks, or moisture brought in by passengers. If left unchecked, it creates an uncomfortable and potentially hazardous driving environment.
How Salt Works as a Natural Dehumidifier
🧂 Salt is hygroscopic, meaning it naturally absorbs moisture from the air. This makes it an effective, natural, and chemical-free way to reduce humidity inside your car. Unlike store-bought dehumidifiers, salt is:
✔ Affordable – No need for expensive moisture absorbers.
✔ Non-Toxic & Eco-Friendly – Safe for you and your car.
✔ Easy to Use – Requires little to no maintenance.
How to Use Salt in Your Car (Step-by-Step Guide)
🔹 Step 1: Take a clean, dry glass or cup.
🔹 Step 2: Fill it with about a cup of salt (coarse or rock salt works best).
🔹 Step 3: Place the glass in a secure spot—such as a cup holder or under a seat.
🔹 Step 4: Leave it there to absorb moisture. Replace the salt every few weeks as needed.
This simple setup requires no effort but provides noticeable results in just a few days!
