Do Baby Wipes Expire? (Plus How To Read The Production Code!)

If you enjoyed this article, please consider sharing it with others!

29Parents can go through hundreds or thousands of baby wipes during the first few years and but if you are worried that baby wipes will expire or go bad then you might be afraid to stock up on this incredibly necessary item. So do baby wipes expire?

We emailed 9 baby wipe manufacturers and most recommend using unopened wipes within 2-3 years of purchase and opened wipes within 2-4 weeks after opening. Baby wipes can become less effective if they dry out, mold accumulates, or the wipe solution breaks down. Parents can make baby wipes last longer by storing them in a cool, dry place.

Keep reading to learn more about what makes baby wipes go bad in the first place along with the policy from many popular brands.

How long do baby wipes last unopened?

It is common practice to check the expiration date, best by date, or use by date on food products that you buy in the store to make sure that they are safe for you and your family to eat but most people have probably never looked for an expiration date on a package of baby wipes.

Baby wipes do not typically have an expiration date listed on the package because there is no requirement for manufacturers to provide one. If you ask baby wipe companies how long their products will last, however, most will recommend that you use unopened baby wipes within about 2-3 of purchase to ensure maximum effectiveness.

So, you should expect unopened baby wipes to last several years as long as the seal is intact.

How long do natural baby wipes last?

In my house, we always opt for more natural products and that includes baby wipes. In this case, we look to avoid fragrances and chemicals that could irritate our baby’s skin or cause other issues.

It is more common for natural baby wipe brands, such as Water Wipes, to include an expiration date on their packaging because they do not include chemical preservatives to prevent mold accumulation in their product. While natural preservatives will still do a great job keeping a product fresh for more than a year, they will go bad relatively faster than baby wipes filled with synthetic preservatives.

In reality, any package of baby wipes should last for many years provided that it has been properly sealed and stored in a cool, dry place.

Next, let’s check out the most common reasons why baby wipes would go bad or expire.

Where would I find the expiration date on the package?

If you are looking for the expiration date on baby wipes in the store or ones that you already own, it is actually pretty likely that you won’t find one. As I mentioned before, most major brands don’t seem to list dates at all and instead just have a production code for their own internal use.

Among the ones that do offer dates, it’s usually printed underneath the flap on the bottom or on the edge of the packaging – basically somewhere out of the way of their marketing space. While some brands will include the expiration date directly on the package, many use a production code instead. There may be letters at the beginning of the code, but the first numbers will indicate the date of manufacture.

Here are a couple of common ways the production code may be displayed, but most will use the Julian calendar. For this example, let’s use the production code in the image below (AB16321 10130 15:23:26). This – and most production codes – use a Julian calendar, meaning that the date is shown in five digits. The first two numbers indicate the year of manufacture (2016) and the next three are the day of the year (321).

If you’re like me, you don’t know what the 321st day of the year is off the top of your head, so I recommend using this Julian Date Converter, which tells me the package was manufactured on November 16, 2016.

How to read the production code on baby wipe packaging
To find the expiration date of baby wipes, flip the package over and look around the sealed flap. Many brands include the date of production instead of an expiration date. In that case, you’ll need to convert the five digit Julian date into your preferred calendar. Most brands have an expiration date of two years from the date of manufacture.

Just in case it saves you a little time, you can check the table below to see whether or not your manufacturer includes a date along with their stated policy (if any) as well as the recommended shelf-life of each brand.

How long do open baby wipes last?

Once the seal on a package of baby wipes has been broken it is only a matter of time before the wipes will dry.

Open baby wipes will generally last several weeks before drying out. Using an airtight baby wipe container after opening can help baby wipes last even longer after opening.

If you aren’t able to use your baby wipes quickly enough after you open them then you will likely start to notice one of three things happen that we’ll discuss next.

Why do baby wipes go bad or expire?

Like I mentioned before, baby wipes don’t really ‘expire’ so much as that over time they can start to dry out, lose effectiveness, or develop mold. This is completely natural and there isn’t much you could do to eliminate these problems altogether.

So, instead of asking ‘Do baby wipes expire?’ you should probably be asking ‘Does it really matter?

To avoid having issues with product complaints and generally save their butts from any sort of legal entanglement from wipes that are past their prime, manufacturers are usually going to have some kind of policy on baby wipe expiration or at least a use-by date.

Why baby wipes go bad
Baby wipes do not usually have an expiration date, but they can become less effective over time. If baby wipes do expire, they may dry out, lose effectiveness, or even mold.

Let’s look at each of these issues and see what’s going on with them:

Wipes dry out

Even in a ‘sealed’ package of wipes, water can still evaporate and find its way out through tiny gaps and tears over time, drying out the wipes.

If you think this is impossible, try leaving a package of wipes in your trunk for a few months during the summer and see whether or not they are still as moist as the day you bought them. My guess is they will be totally dry! Once the water starts heating up, it expands into water vapor and puts extra pressure on the inside of the package, creating more tiny gaps in the process.

Considering the fact that a lot of baby wipes these days are 99% or more water, this is the biggest potential threat.

Losing effectiveness

Depending on the ingredients included in the baby wipe solution, the formulation can lose its effectiveness over time due to evaporation (chemicals can evaporate too!) or interaction with the air. This issue can be especially true with baby wipes that are meant to condition or moisturize because natural oils can settle out of the solution or accumulate in the bottom portion of the stack of wipes.

This issue probably ranks lowest on the list because most natural wipes are very mild and contain relatively few ingredients in the first place.

Developing mold

Unfortunately, this is a real issue that does happen, especially in natural wipes that don’t include a lot of chemically antibacterial agents, alcohol, or other sanitizers.

Usually, these wipes are made using highly filtered and sanitized water in the first place, but some bacteria are bound to stick around and, of course, contamination can happen to anything. Over time, these bacteria can gain a foothold and develop as visible mold. If this happens, it’s best to just throw them out.

Remember that even if you take excellent care of your wipe supply once you get it back to the house by avoiding hot car trunks and the like, your baby wipes have already had quite the journey to get there. They have probably been sitting in a hot warehouse, transported in a hot truck, and then sitting in the retail store for who-knows-how-long before you decided to restock.

So, don’t freak out if you open up a fresh package, even within its use-by date, and it’s not looking so good!

Are expired baby wipes still safe to use?

The good news for your wallet is that overall, baby wipes that have expired are probably still completely safe to use. Remember, these dates are really more like a ‘best by’ date in the first place and after the date is passed it’s really up to you to make a judgment call on whether or not you want to use them.

Expired baby wipes are safe to use as long as they are still sealed before you open them, they do not have any mold accumulation, and they haven’t dried out completely.

Just like brand new wipes, the biggest concern that you would have about expired baby wipes is that they have some mold accumulation that could irritate your baby’s skin or make them sick. Like I said before, it’s probably best just to discard these wipes and start over with a fresh pack. There’s no sense in taking chances there.

For old wipes that are just dried out and not looking so hot, you could still get a lot of use out of them even if they aren’t your go-to for your baby’s bottom. They can still be called into service to clean up spills or other messes around the house. In fact, a little dryness might be an added benefit here when it comes to absorbing liquid messes!

If you are looking to replace some old wipes, I urge you to check out my diaper wipe resource that includes affordable, high-quality, and biodegradable options that don’t include harsh chemicals that could irritate your baby’s skin. The environment will thank you!

What if my baby wipes smell bad?

If you just opened up a package of baby wipes and they stink or otherwise smell off then you might be worried that something is wrong.

Usually, a smelly baby wipe will have two causes:

  • Mold –┬áThe first thing you should do is check for mold inside the package. Most people can identify the musty, mildewy smell of mold fairly easily and a quick visual inspection will confirm that there is something growing inside the wipes and it is time to throw them away.
  • Fragrance-free – If you think that your fragrance-free wipes stink then you won’t be the first parent to think so, I promise. In fact, I’ve tested many, many fragrance-free wipes over the years and almost all of them smell horrible to me because there is no fragrance to cover up the natural smell of the wipe fabric or other ingredients.

Again, mold is a definite reason to go ahead and throw away your wipes. Using a moldy wipe on your little one could lead to a diaper rash, or worse!

Can I rehydrate baby wipes that have dried out?

Yes, absolutely!

Of course, it depends on the situation, but in general, it is completely fine to rehydrate dried-out baby wipes to let them live another day. I’m not about to buy more baby wipes to replace the ones I have unless I absolutely have to.

In fact, I actually created an entire resource all about rehydrating dried-out baby wipes if you want a complete guide.

Briefly, the best way to bring old baby wipes back to life is just to mix a few drops of baby shampoo and lotion into water, pour it into the baby wipe package, and shake it up! You could also add a drop of essential oil for fragrance but be careful to ensure that it will not irritate your baby’s skin.

Even though you are adding a little soap with this method, however, you will still be adding water that hasn’t been filtered or sanitized nearly the same way as the original manufacturer so you could be introducing some foreign bacteria or contaminants into the mix, spending on the quality of your home tap. It’s likely not a huge deal but it’s probably best to use up the rest of the wipes within a couple of weeks just to be safe!

One caveat when it comes to rehydrating wipes: At least one major manufacturer recommends against adding water to dried-out wipes because it would dilute their original solution and could make them less effective. Of course, they are also in the business of selling more baby wipes so use your best judgment!

Related Questions:

Can baby wipes expire before I purchase them in the store? Yes, they can. Products like baby wipes can sit on store shelves for a long time and aren’t checked as often as food because of their long shelf life. If you find that you’ve purchased an expired product, hang on to your receipt and reach out to the store you bought it from or the manufacturer for a refund or replacement!

Will a wipe warmer affect the life of a baby wipe? Yes, wipe warmers can cause wipes to dry out faster due to the heating element in the unit. It is recommended that you use wipes in a warmer quickly to avoid running into this issue and keep the majority of the wipes in the original container, replacing them as needed.
