When should you throw away your mascara? Your pillowcase? Did you know that smoke alarms should be replaced after a certain amount of time? If not, you’re not alone. Many household items don’t have expiration dates, making it difficult for most of us to know when it’s time to toss them. Fret not! Here are nine items sitting around your house that you should probably get rid of right this minute.
1. Pillowcases
Replace your pillowcase every year. Otherwise, your face is coming into contact with all your hair and body oils, which causes bacteria. Even worse? Bacteria is a breeding ground for dust mites. Gross!
2. Mattress
While it can be a little pricey, mattresses should be replaced every five to 10 years, especially if you have trouble sleeping.
3. Smoke alarms
Smoke detectors become less sensitive after 10 years. Here’s a scary statistic: One-fifth of U.S. homes have smoke alarms that don’t work, according to the National Fire Protection Association. Don’t be one of those households! Test your smoke detectors regularly and be sure to replace the batteries every year.
