3 Products You Shouldn't Leave in a Hot Car

January 22, 2019

Once you park at the pool, you can’t wait to cool off with a dive into the deep end. But while you’re cooling off, your car is heating up to a scorching 140 degrees. And just like you during yard work, dental items start to sweat. Don’t leave these 3 items in the summer’s sun.


Plastic water bottles contain low levels of bisphenol A (BPA).—Though the FDA has deemed the amount of BPA safe, the levels skyrocket from safe to dangerous after being left in extreme heat. This includes bottled water bought in bulk from your wholesale store. Enlist an assistant to help haul the water out of your trunk and into your fridge. When we’re thirsty, we’re desperate—sometimes desperate enough to drink from the bottle you found rolling around on your floorboard. Keep H2O indoors or buy a BPA-free bottle instead. Learn how to drink more water.


Thankfully with toothpaste, chemicals aren’t a concern but quality can be. Hot temps can cause ingredient separation and a melted mess. Brands made with natural ingredients are more susceptible to melting. And the mint flavoring in your favorite tube may start to disintegrate, leaving you with less-than-fresh breath.


If you keep your brush in your bag (next to your lipstick and in-case-of-emergency crayons), other items can melt on and around your toothbrush. Brushes are a breeding ground for bacteria to begin with. Not to mention germs are more active in warmer weather, so it’s best to let your backup brush breathe. Safely store out of the sun and in a second location—your desk drawer, for example.

Make a conscious choice to keep products indoors this summer. But if you must leave them in the car, park in the shade and make your stop snappy.
