When the temperature rises, leaving certain items in your car can spell disaster. Knowing what to avoid can protect both your belongings and your well-being. High heat can cause various products to melt, lose effectiveness, or even become dangerous.
It’s not just about comfort; some items can pose serious safety risks when left in a hot vehicle. From medications to electronics, being aware of what not to store can save you from unnecessary headaches down the road.
1. Disposable lighters

Leaving disposable lighters in a hot car isn’t a good idea. The heat can build up pressure inside them. This might lead to explosions, which can damage your car.
Even if you think they’re safe, accidents can happen. A lighter might not explode every time, but it’s better to avoid the risk.
Instead, keep your lighters in a cooler, safer place. That way, you won’t have to worry about unwanted surprises. Just think about your safety and your car’s interior!
2. Laptops

Leaving your laptop in a hot car can cause serious damage. High temperatures can ruin your battery life and even affect the screen.
If your laptop gets too hot, it might overheat and lead to internal component failure. It’s best to take your laptop with you or store it in a cooler place.
Using an insulated cover can help, but the safest bet is to keep it out of the car altogether. Protecting your tech means longer life and better performance!
3. Cameras

Leaving your camera in a hot car can cause some serious damage. Most cameras are rated for temperatures between 32°F and 104°F. It’s best to avoid leaving them in extreme heat for long periods.
Heat can warp the internal electronics and damage sensitive components. Lenses may be safe for short bursts, but prolonged exposure can lead to issues, especially if they’re in direct sunlight. To keep your gear safe, take it with you whenever you can.
4. Overnight bags

Keeping an overnight bag in your car might seem practical, but it’s a bad idea. The heat can damage items like electronics, toiletries, and clothing.
Toiletries like shampoo or lotion can break down or lose effectiveness in high temperatures. Clothing can also get musty or wrinkled.
If you need an overnight bag, store it in a climate-controlled area. This way, your essentials stay in good shape and ready for when you actually need them.
5. Concealer

Leaving concealer in a hot car can be a bad idea. The heat can cause it to separate or change texture, making it harder to apply later.
You want your concealer to go on smoothly, not in clumps. High temperatures can also affect the ingredients, which might lead to skin irritation.
To keep it in top shape, store it in a cool, dry place. Your makeup routine will thank you for it!
6. Moisturizer

Leaving your moisturizer in a hot car can change its formula. High temperatures can break down the ingredients, making it less effective.
You might notice changes in texture or smell. If it feels weird or smells off, it’s best to toss it.
To keep your skin hydrated, store moisturizers in a cool, dry place. This way, they’ll stay fresh and do their job properly when you need them.
7. Lipstick

Leaving lipstick in a hot car can lead to some messy consequences. High temperatures can cause it to melt and lose its shape.
When lipstick melts, it can become hard to apply smoothly and may affect its color and texture.
If you’ve left your lipstick in the heat, check its consistency before using it. It’s better to be safe and get a new one if it’s unusable.
8. Hairspray

You might think it’s convenient to leave your hairspray in the car, but that’s not a good idea. Aerosol cans are sensitive to heat and can explode in high temperatures.
In a hot car, the pressure inside the can rises and can lead to dangerous situations. To keep yourself safe, always store hairspray in a cool, ventilated place away from direct sunlight.
When you’re heading out, take it with you instead of leaving it in the vehicle. Staying safe is what matters!
9. Wine bottles

If you’re a wine lover, keeping wine bottles in a hot car can really ruin your day. Heat can cause chemical reactions that change the flavors and aroma of the wine.
Ideally, wine should be stored at temperatures below 78 degrees Fahrenheit. Anything hotter can lead to “cooked” wine, which may taste off.
Pay attention to signs like changes in color or the cork pushing out. If you’ve left a bottle in the heat, it’s best to check before serving.
10. Soda cans

Leaving soda cans in a hot car can lead to some messy situations. As the temperature rises, the pressure inside the can increases due to the expanding gas.
This can result in the can warping or even exploding, creating a sticky mess in your vehicle.
It’s best to keep soda cans out of your car during summer heat to avoid any surprises when you return.
