Perfumes that contain essential oils last around 3 years unopened, but only 2 years when opened. This is because essential oils are natural and natural ingredients often don’t have a super long shelf life. Your perfume won’t make you ill if you use it, but the smell won’t be the same or last as long.

Disposable razors

Smoke detectors

Yes, even canned foods. Certain types of food store for way less time than others, like highly acidic foods. Tomato sauce is safe for around 18 months, but other low acidic foods like green beans are good for 5 years. Any bulging, rust or discoloration is a sign to not eat any of the contents.

Makeup sponges

Often your foundation or blush stains can hide the color changes of the sponge and make it look like it’s still fine. But really, they should be replaced every 3 months as they can quickly build up bacteria or mold, especially inside where you can’t see.

Hand sanitizer

If you’ve had that one bottle in your bag for years, it’s probably best to throw it away. Hand sanitizers only have an effectiveness for around 2 years after opening, because the chemicals get exposed to air. Make sure to buy a fresh bottle for your purse.
