Smoke/carbon monoxide detectors and their batteries


As per the U.S. Fire Administration, the rule of thumb is to typically replace the entire smoke or CO alarm by the date of manufacture printed on the alarm itself. Test the alarm every single month and replace batteries twice a year, at least. Here are the little things that could be making your home a fire hazard.



Dental company Oral-B recommends replacing your toothbrush every three months. If you notice the bristles are frayed, replace it sooner. It's also a good idea to replace your toothbrush after you're sick to avoid spreading germs to fellow toothbrushes nearby. While you're at it, avoid these common toothbrushing mistakes.




Most makeup has a printed recommendation on the package for how long you should use it from the time you open the package. Most powders and eye shadows can last 12-15 months (some powders list 30 months), but liquids like mascara and eyeliner have a shorter shelf life. Always replace makeup if you've had a cold sore or pink eye. Here are ways you didn't realize your makeup could be making you sick.

Makeup brushes


We use these almost every day and rarely wash them; never mind replace them. If you notice the bristles on the brush are fraying or can't remember the last time you replaced them, toss them! Here are some gross things that can happen when you don't wash your makeup tools.



Sunscreen has a shelf life too. To be safe, replace those half-filled leftover bottles every season. Expired sunscreen may not be as effective. Here's what all those labels on your sunscreen really mean.



The folks at Safebee recommend replacing your hairbrushes every one to two years, but the best gauge is wear and tear, not the calendar. Round brushes, especially if you use them while you blow-dry your hair, tend to have the shortest lifespan. If a plastic-bristle brush is losing the little round balls at the end of the bristles, it's time to toss it. Your hairbrush wishes you knew these secrets for having healthier hair.



Most people try to squeeze as much use out of their razors and switch when they start to get razor burns or nicks. Grooming Lounge recommends replacing your multi-blade razor cartridges out every three to four shaves. Here's the real difference between men's and women's razors.

Cabinet liners


Have you taken a look at those ratty cabinet liners underneath your dishes? They are probably discolored, ripped, or full of crumbs or other dirt. Gross. Toss them and put some new ones under there which will help protect your dishes, mugs, and glassware from chips.

Bed pillows


You spend hours on it every night drooling, sweating, and jamming your face and hair up into your pillows. Similar to mattresses, pillows harbor dust mites. Allerease recommends replacing your bed pillow every two to three years, but every year if they are used nightly. This is the secret to getting fluffy hotel-like pillows at home.

Kitchen sponges


According to WebMD, your kitchen sponge is one of the biggest germ magnets in the whole house because the moist, micro-crevices that make a sponge such an effective cleaning device also make a perfect home for germs (and more difficult to disinfect). Clean your kitchen sponge by wetting your sponge and putting in the microwave for two minutes to disinfect and replace your sponge at least every three weeks.
