What is the shelf life on these? Is there an expiration date? Do they become less effective over time?

Hi J. Steichen -- Yours are very interesting questions. Yes, there is an expiration date on the package. The questions are interesting, because the instructions are very specific for the amount of contact time the wipe should have to kill certain bacteria (30 seconds) versus certain other bacteria (1 minute) versus certain virsuses (1 minute). One would certainly sense from these instructions, then, that shelf life would be important to the efficacy of the product. However, for the best answers, may I recommend to you that you telephone the manufacturer at 1-800-234-7700 or go to www.cloroxhealthcare.com to see if you might be able to submit your questions.

yes there is a shelf life I guess. Mine said Oct. 2014 which probably wasn't even a year after I got it.

Yes, an expiration date is stamped on the package. The one I just purchased has an expiration date of 30 October 2016. I spoke to Clorox Healthcare Customer Service and was told the effective life is 24 months from the date of manufacture. The label also says, "Store this product in a cool, dry area away from direct sunlight and heat to avoid deterioration."

the container I just received says November 2016. I have no idea if they lose effectiveness - I never have them around long enough to wonder ! there is ample liquid - they don't dry out. perhaps contact Clorox re: effectiveness over time. I love this product.

I have no idea what the shelf life is. I just buy about a 2 month supply at a time. Check the expiration date on the package.

I honestly don't think they have a use-by date. They're wheat-based so I'd say they stay fresh for at least 4-6 weeks. I wish I could tell you more but my husband never lets them stay on the shelf too long. He eats them upwell within their expiration date!

As long as they stay in a fairly dry environment, I haven't found a shelf life. I've had mine for a few months now, living in humid Florida with no AC, and I've had no issues. Keep the packages dry, and they keep for months.

I don't believe there is any expiry date. In my experience, the product remains effective even if it ages to the point of becoming a bit dry (although it rarely lasts that long).

According to the company, they have a shelf life of 4 years. However, there's no way of knowing exactly how long the batch you buy has been sitting around...

Hi Sean. You know that is an excellent question; I assume you are speaking to shelf life?. I actually do not know the answer to that. When I purchased mine, I used them right away and never looked to see any dates of expiration.

I have had mine for several months and the expiration date 7/20/2018. It is my understanding that they are actually useful foe much longer then they are dated for. Hope this helps!

My wife has been eating them for a year with no effects. There is not an expiration date listed on the individual packages and we have moved them to a different container. I would not be concerned about a few months whatsoever.

The "date best used by" has always been at least one year from the date I've purchased these. I am not sure about the "shelf life" because they ALWAYS get eaten within a few months - I buy them by the case. I store them in the cupboard in the kitchen, and they have never lost their crispiness, flavor or any quality.

I'm not a seller, but a customer like you. That being said, I have used these products for a few years and have never had any problem with shelf life.

I've had them last for years, with no adverse effects, so long as they are dry when stored. Hope this helps.

I don't know of an actual expiration date. But, they have a shelf (unused) life of 10 years.

From investigating on the internet, the shelf life is 5.5 years from date of manufacture. I would expect that it probably is effective much longer than that if kept in its original unopened pouch. At worst, I would expect it to be much better than nothing even after seven or eight years.

Not real sure about shelf life. Might want to check on-line for more information.

If you order from a reputable company, the shelf life are well within safe sell dates. Some expiration dates are from 3 months to next year.

Excellent question, because I thought the same thing. I could not find an expiration date anywhere on the box they came in, nor on the syringes. I have tooth sensitivity when I use them, (which is common with me), so they must still be active. I do keep them stored in the refrigerator.
