The easiest way to tell if your cleaning supplies are expired is simply to check the date printed on the bottle or box. If there isn't any expiration date, there may be a manufacture date—then use the general guide below to determine if the product is expired. Pro tip: The next time you open a new cleaning product, use a permanent marker to date it so you never have to wonder how long it's been opened. If you're storing your hand sanitizer in a hot car, it could be losing potency faster and may end up containing less than 60 percent alcohol the amount needed to be sufficiently effective, according to the CDC before it even reaches its expiration date.
If you find some decades-old bleach in the back of your cleaning cabinet, how do you get rid of it safely? A small amount can typically be diluted in water and poured down the sink. For larger amounts, check if there are any disposal instructions printed on the container.
If not, call your local hazardous waste disposal facility for their recommendations. Keep in mind that certain cleaning chemicals should never be combined —such as bleach and ammonia—and that holds true when disposing of them, too. Pouring these chemicals down the sink at the same time can create a toxic gas. Cleaning and disinfecting products also have a "best by" date, and swiping, spraying or squeezing them past their prime could mean they're killing fewer germs if any at all.
Read on to discover how long you can expect hand sanitizers, disinfectant sprays and bleach solutions to last. As we mentioned in our overview about why you shouldn't store your hand sanitizer in your car , the active ingredient in hand sanitizer, alcohol, can begin to evaporate when exposed to high heat or air.
That means the alcohol percentage drops below what is touted on the label, making it less strong at fighting off germs. All hand sanitizers are regulated by the Food and Drug Administration FDA , and go through testing to guarantee how long they are effective. Most often, the dates on the bottle refer to when the alcohol falls below 90 percent of the total potency percentage stated on the label.
Store-bought hand sanitizers generally last two or three years, max, and the WHO formula for homemade hand sanitizer has been tested and proven to have a shelf life of 19 months. Cleaning products are more likely to lose their potency than actually spoil.
For example, bleach will begin to go bad between six months to a year after you've opened it. After that six month mark, the disinfectant loses an estimated 20 percent of its effectiveness. However, products like glass cleaners have a longer shelf life; some are able to maintain peak effectiveness for close to two years. With the exception of bleach and other short-lived products, most of your favorite cleaning supplies should last long enough for you to get your money's worth.
If you're worried that some of the products lurking under your kitchen sink or in the back of your linen closet have expired, you can always check with the manufacturer to be sure. Some laundry detergents , like All, have the date they were manufactured stamped on the cap or bottle to help you keep track of storage time.
Using detergents passed their prime may not get your clothes as clean as fresh detergents will. Oxi Clean Powde r: In order for the product to deliver on its unlimited shelf life , the powder must remain dry and kept in a cool location.
