You’d never leave a gallon of milk in your trunk during a July heatwave, right? Well, winter has its own set of car-destroying, mess-making, regret-inducing mistakes.
Leaving the wrong stuff in your car when it’s below freezing can be just as bad – or worse – than when it’s too hot. If your car turns into an accidental walk-in freezer, bad things happen.
Here are six things you should never leave in your car when it’s below freezing.
Aerosol Cans
You know those cans of hairspray, deodorant, or air freshener rolling around your trunk? Yeah, they’re basically little pressurized time bombs in cold weather. Extreme temps can make them explode. Nothing says “good morning” like a can of Febreze blowing up in your backseat.
Canned Food
Bring those groceries in asap! Freezing temps can make the food inside expand, which can cause tiny cracks or even cause the can to swell. That’s how bacteria sneaks in and ruins Taco Tuesday. The USDA says if it looks swollen, toss it. If it doesn’t look swollen, maybe still toss it. Just don’t trust a cold can.
Eggs
Yes, eggs freeze. And no, they don’t bounce back from it. If you leave them in the car after a grocery run and they freeze and crack, they’re no longer safe to eat. Also, egg goo in your back seat is no fun at all.
Electronics
Phones, tablets, laptops – basically your entire digital life – is not a fan of the freeze. Cold weather can make batteries act weird, screens go wonky, and when they warm back up, condensation inside can fry them. So unless you want your iPad to become a very flat, very useless ice cube, bring it in.
Medication
Some medications, like insulin, can become unstable or even useless if they freeze. The rule of thumb with any frozen meds is: don’t guess, just toss – or talk to your pharmacist before you end up with more problems than you started with.
Loved Ones
This should go without saying, but just in case: don’t leave pets, kids, or anyone else in a freezing car, even for “just a sec.” If the idea of sitting in an ice-cold vehicle makes you miserable, don’t subject Grandma or the golden retriever to it. Your car turns into a walk-in freezer with seatbelts faster than you think.
