8 Things You Shouldn’t Leave in the Car
Medication
Most medicine should be left at room temperature, but a car will rarely stay at that point when not in use. Heat probably won’t make your drugs directly harmful, but it could make them less effective.
Electronics
Beyond the expense of the devices themselves, gadgets like laptops, cell phones, and thumb drives contain information that could be easy to steal.
Sunscreen
Ironically, the active ingredients in sunscreen break down in high heat. Leaving it in the car on a hot day could reduce its effectiveness.
Water bottles
Letting a bottle sit in the sun and heat up could cause these chemicals to leach into the water.
Handbag
Leaving a purse or wallet in plain sight makes your car a target for thieves, even if you’ve locked your doors or taken the valuables out of your bag.
Glasses
Heat can warp plastic frames and make metal ones too hot to wear. Leaving your glasses or sunglasses on the dashboard is even worse because the windshield could attract sunlight like a magnifying glass,
Passport
Never leave a passport in the car while traveling, even if it seems like it’s too bulky to carry around. Identity theft is even easier with a passport than with a driver's license,
Wine
If the bottle gets too hot, the flavor could be affected, and the liquid could expand enough to seep around the cork or push the cork out a bit, contaminating the wine inside.
