Do you know how old your furniture polish is? If you have to think back to a specific purchase and then do math, chances are it's expired. And what about those other products you have to reach way back in the cupboard for — those products you only use a few times a year?
Yep, almost all cleaning products expire — but what does that mean exactly? Simply put, it means that they'll break down and become less effective. You can still use them, you just might have to use twice as much, or put in a little more elbow grease to get them working. So if you're a coupon clipper and have a back stock of laundry detergent to last 10 years, you might want to look into donating at least 9 years worth (or open up a laundromat!).
