Freezers are a lifesaver—stashing leftovers, preserving fresh produce, and keeping the ice cream rock-solid. But just because it’s cold and convenient doesn’t mean everything belongs there. In fact, tossing the wrong items into the freezer can cause anything from a kitchen mess to a real safety hazard.
Here are five things you should never freeze—and why.
Glass Mason Jars: That leftover soup or homemade sauce may seem perfect for a Mason jar, but many glass containers aren’t freezer-safe. When liquids expand in freezing temperatures, the glass can crack or shatter. Unless your jar is labeled “freezer-safe,” opt for plastic or silicone containers instead.
Carbonated Drinks: Putting a warm can of soda or sparkling water in the freezer may seem like a quick way to chill it, but it can explode. As the liquid freezes and expands, pressure builds up quickly in sealed cans, turning your freezer into a fizzy mess (or worse, a mini bomb).
Batteries: Old-school advice suggested keeping batteries cold to make them last longer, but this myth has been debunked. Duracell recommends storing batteries at room temperature in a dry place. Freezing them can actually reduce performance and cause damage due to condensation.
Makeup & Skincare Products: That serum or lipstick might contain oils and delicate ingredients that don’t respond well to freezing. Instead of prolonging their shelf life, freezing can change their texture, separate ingredients, and introduce bacteria once thawed. Store in a cool, dry cabinet—or a beauty fridge, if you’re fancy.
Electronics: Never toss overheated phones or gadgets into the freezer. Rapid temperature shifts can cause internal condensation or crack sensitive components. Let them cool down slowly indoors instead.
Freezing is a powerful tool—just use it wisely!
