Are you an excellent couponer, always finding the best deal on whatever household item you can? Perhaps you enjoy warehouse shopping to snag deals on bulk purchases or just dislike shopping enough that you stock up heavily when you get to the store. Whatever the reason, laundry soap might be on your list of things you seldom buy. But when you do—The more you can get your hands on at once, the better.
Many, possibly including you, also enjoy creating their own laundry detergent, sometimes in batches larger than are practical before they become lumpy or difficult to use. It’s sometimes best to produce a single large batch instead of smaller ones, simply for efficiency or cost savings.
In either case, you may wonder, does laundry detergent expire?
In fact, it can and does expire. You may even notice a “best used by” date stamped on liquid detergents. While using laundry detergent after its expiration days isn’t inherently bad, doing so means the product may have lost some effectiveness and could leave your clothes less than perfectly clean. Following are more answers to this more-common-than-expected question and how to address the issue.
Does Laundry Detergent Expire?
Liquid Formula
Liquid laundry detergents typically have a shelf life of about six months to one year after opening. Over time, exposure to air and temperature fluctuations can deteriorate the detergent’s effectiveness. The key components in liquid detergents, such as surfactants and enzymes, may lose their potency, resulting in reduced cleaning power.
While laundry detergent losing some effectiveness is one issue, a more immediate concern is that lumpy soap has the potential to gum up your washing machine’s liquid dispenser.
However, if you decide to use the old soap anyway, mixing it with four to six parts water to one part soap and vigorously stirring or shaking the mixture can dilute the solution to a usable product. Pour into the drum of the washing machine, bypassing the dispenser. Check your laundry load during washing to ensure proper suds are present, indicating that the detergent is doing its job.
Single Dose or Pods
Single-dose laundry pods have a relatively longer shelf life compared to liquid detergents, usually ranging from one to two years. However, they can also deteriorate if exposed to moisture or extreme temperatures. The pod’s outer packaging is designed to protect the contents from such elements.
Powdered Formula
Powdered detergents are known for their long shelf life, often lasting up to two years or more when stored properly. Powdered detergents are less susceptible to degradation from moisture and temperature fluctuations compared to their liquid counterparts.
However, they’re not immune to the effects of airborne humidity or moisture from other sources, which can cause clumping and caking that won’t likely dissolve well in the wash and could leave a chalky residue on clothing, particularly on darker-colored items.
While you may opt to discard or repurpose the product, resurrecting the hardened or cakey powdered detergent is often possible without much difficulty. To do so, mix one part cakey powdered detergent with four to six parts water in a bowl or container with a tightly fitting lid. Vigorously stir, shake, or otherwise agitate the solution to dissolve as many clumps as possible.
Pick out and discard any leftover clumps before using the diluted mix. Administer the soapy mix directly into the washing machine drum and wash your clothes normally without adding more detergent to the load.
Laundry Detergent Sheets
Laundry detergent sheets are a relatively new product on the market. Like powdered detergents, they tend to have a longer shelf life, often lasting up to two years. Proper storage is crucial to maintain their effectiveness.
Homemade and Natural Detergents
Homemade and natural laundry detergents may not contain the same stabilizers and preservatives as commercial products. Their shelf life can vary depending on the ingredients used, but they are generally more susceptible to spoilage over time.
However, there are many benefits to using homemade detergents, such as those made with ingredients like baking soda, Borax, or other products, that are appealing despite their shorter shelf life and convenience challenges.
Allergy sufferers may not have many options except to use less harsh products than those found in commercially available detergents. Additionally, homemade laundry detergent production reduces waste and is generally more environmentally friendly than commercial alternatives.
The challenges involved with homemade laundry soap are that it can clump and cake easier than store-bought varieties, and liquid versions often separate and lose their effectiveness faster. Mold can also happen due to the lack of powerful commercial mold inhibitor additives to combat it.
In the case of mold, discard the product immediately. However, there are a couple of ways to ensure your homemade detergent is always up to the task at hand. First, create small batches that you, or you and several people you share it with, can use up within a month or two. Second, always store homemade soaps in well-sealed containers and out of sunlight or damp conditions. Taking these steps will give your homemade detergent the best chance at the longest shelf life possible and ensure it performs as it should at laundry time.
Is it OK to Use Expired Laundry Detergent?
Using expired laundry detergent is generally safe but may result in less effective cleaning. You may need to use a larger amount of expired detergent to achieve the same level of cleanliness. If your detergent is only slightly past its expiration date, it is likely still usable, especially if it has been stored properly.
What Else Can I Use Expired Laundry Detergent For?
Expired laundry detergent can serve several alternative purposes around the house. Here are a few ideas.
- Cleaning: Expired detergent can be used as a cleaning agent for various household surfaces, such as floors, countertops, and sinks.
- Pre-soak for Stains: You can use expired detergent as a pre-soak for stained clothing or as a stain remover for tough spots.
- DIY Liquid Soap: Mix expired liquid detergent with water to create a homemade liquid soap for handwashing or cleaning dishes.
- Toilet bowl: Using expired laundry detergent will work perfectly in the toilet bowl.
- Cleaning Pet Areas: You can feel safe using expired detergent to clean pet bedding, bowls, and toys.
Proper Storage Locations and Conditions
To extend the shelf life of your laundry detergent, follow these storage guidelines:
- Keep in a Cool, Dry Place: Store detergent in a cool, dry location away from direct sunlight and humidity. Extreme temperature fluctuations can cause liquid detergents to degrade.
- Seal Tightly: Ensure that the detergent containers or bags are tightly sealed to prevent moisture from entering.
- Follow Manufacturer Recommendations: Adhere to any specific storage instructions provided by the detergent manufacturer.
How Do You Know if the Laundry Detergent is Bad?
Expired or spoiled laundry detergent may exhibit the following signs:
- Separation: Liquid detergents may separate into different layers, indicating a loss of consistency.
- Clumping: Powdered detergents can form clumps or harden over time, rendering them less effective.
- Unpleasant Odor: Detergents with a rancid or foul smell should be discarded.
- Ineffectiveness: If your detergent fails to produce suds or clean clothes as effectively as before, it may be past its prime.
Does Laundry Fabric Softener Expire?
Laundry fabric softeners typically have a longer shelf life than laundry detergents, often lasting up to two years or more when stored properly. The signs of expiration for fabric softeners are similar to those of detergents, including changes in consistency, separation, or an unpleasant odor.
While laundry detergents do have expiration dates, they can often still be used safely and effectively past those dates if stored correctly. However, you may need to use more expired detergent to achieve the same results.
Before committing to using old detergent, check your watching machine’s user manual for any concerns the manufacturer may have about using more than the recommended amount of detergent, and proceed using the directions provided if any exist. Remember, you can always repurpose or discard the soap if you have concerns.
Always inspect your detergent for signs of spoilage and consider repurposing it for other cleaning tasks if it has passed its expiration date. Fabric softeners also have a shelf life but generally last longer than detergents when stored properly.
