Put a glass of salt in your car. This is a vital hack every driver should know. Cop told me about this

💡 Pro Tip from the Cop:

“If your car sits for a few days, especially in damp weather, leave a cup of salt inside. It keeps the air dry and helps prevent mold. You’d be surprised how many people come in complaining about foggy windows or weird smells that could’ve been avoided with something as simple as salt.”

✅ Final Thoughts: Smart, Cheap, and Actually Works

I was honestly skeptical at first, but now? I always keep a little glass of salt in my car — especially during winter. It’s cheap, natural, takes no effort, and makes a noticeable difference in air quality and visibility.

It’s the kind of old-school tip that works so well, you’ll wonder why no one ever told you about it sooner.

Thanks to that friendly officer, I’ve added this to my list of essential car care hacks — and now you can too.
