Fermenting is a science, and a bit of an art. It requires care in a few specific things, but doing it right is not particularly complicated. We provide instructions that are accurate to the best of our knowledge, and which are based on the methods we successfully practice ourselves. There are no guarantees of success or safety with fermented foods. While properly fermented foods are not only safe, but healthy to eat, it is up to you to follow instructions to ensure safety, and to trust your eyes and nose, and don't eat things that do not look or smell like food. We offer no guarantees of success with our product. We do warrant that it is as described, and will do what we say it will, but how you use it is your choice.

I am allergic to just about every chemical out there that promises to sterilize surfaces. I also find that they do NOT in fact sterilize surfaces, they just kill the friendlies and leave the resistant nasties to grow. So if you are frantically bleaching every surface in your home in a fevered effort to keep things clean, you’ve defeated yourself.

There is, in fact, no such thing as truly sterile except at very high heat and only while objects STAY at very high heat. Once they cool off, germs inevitably collect again.

The most important thing about cleaning is to simply remove the stuff in which microbes grow. The yucky visible stuff. Water, then, is our most important cleaning substance!

Some things just come OFF a bit better with a cleaner. And a good cleaner can help reduce grease, dry more evenly on smooth surfaces (like glass), and leave a pleasant smell behind.

What if the cleaner also left behind a nice complement of friendly microbes? Even better than a sterile kitchen or bathroom – one that naturally fights harmful microbial lifeforms.

The natural solution then, is a Probiotic Cleaner, hop over to this site and learn its effects on home cleaning. A quick web search shows that this is not at all a new idea. Many companies produce cleaners into which they have dumped a concentration of specific bacterial strains. They usually suspend them in substances in which they cannot possibly survive for very long, and then package them entirely in plastic, which helps kill the good ones and fosters a few nasties.

Not really an effective Probiotic Cleaner!

A fermented cleaner is entirely different, and has some particularly wonderful benefits.

  • Completely non-toxic. If your kid drinks the stuff, it would not be any worse than having him drink some vinegar water. Made from food ingredients, the cleaner is simply safe!
  • Very earth friendly. Nothing in it that cannot be dumped on the garden, into the compost pile, or even into animal feed dishes.
  • Easy to make. Just takes some time to ferment.
  • Inexpensive to make. Simple ingredients that you can purchase almost anywhere.
  • Creates a general all-purpose cleaner. Use for counters, windows, floors, and any surface that you’d normally disinfect.

The Recipe

Fermented Pro-biotic Cleaner

  • 1 cup lemon juice
  • 1/2 cup RAW apple cider vinegar
  • 1/2 an orange
  • non-chlorinated water that has NOT been sitting for weeks in a plastic container (plastics in contact with water do leach chlorides into the water, which inhibit some types of microbial growth). Freshly filtered water, or well water is best.
  • 1/2 gallon mason jar
  • Fermenta Lock or Fermenta Free airlock lid
  • Fermenta Cap cloth cover or other cloth cover for the jar
  • Blender or Food Processor

Cut the orange into small pieces, and toss it into a blender or food processor, along with the lemon juice and vinegar. Blend until the orange is finely chopped.

Pour out into the mason jar, and fill to the 6 cup mark with non-chlorinated water.

Put the Airlock lid on the jar.

Let sit for 2 weeks. You will first smell a pleasant orange smell on the airlock, and then an alcoholic orange smell. This is normal, and how it should be.

Remove the airlock lid, and strain the liquid. Squeeze out the solids completely.

Return the liquid to the mason jar. Add more non-chlorinated water, just to return it to the 6 cup mark.

Place the Cloth Cap on the jar.

Let sit for 4-8 weeks, or until all of the alcoholic smell is gone, and the smell is more orange vinegar.

Replace the Cloth Cap at that point with a storage lid, and your cleaner is ready to use.

To use, dilute with a ratio of 1 part cleaner to 3 parts water for spray cleaner. Dilute at a 1:10 ratio for other cleaning tasks.

For cleaning that involves a significant amount of grease, add a few drops of dish detergent to cut the grease. Not advised to do this otherwise, as it will interfere with the probiotics.

Now you can clean your way to a truly healthy home.

The ORIGINAL one-way valve fermenting airlock! Imitation IS the sincerest form of flattery, and we have noticed that our product has been copied by other sellers of fermenting products. Remember, if you see someone else selling a one-way valve airlock for fermenting, THEY copied US, not the other way around! Fermenta Lock is still the only original invention, handmade in the US. If it isn't orange, it isn't the original!

We invented Fermenta Lock, Fermenta Free, and the valve used for Fermenta Fido and other Fermenta Airlock products. We invented Fermenta Dunk Extender. Patents are prohibitively expensive, and designed by the government not to protect the rights of individuals, but to provide another source of revenue and control for the government and lawyers. We are good at what we do. We have endless ideas and endless creativity, and competition does not scare us. Impatient thieves do not scare us - they are too busy taking shortcuts to make a success of it anyway, and they won't want to take the effort to actually MAKE a product and fill orders.

So if you want to copy our idea, go right ahead. If you want to market and sell a competing product, you are welcome to do so, as long as you do not patent our idea - we had it first, and our posts on FaceBook announcing the invention and launch of it will prove that. This idea is officially in the public domain, placed there by us. We will NOT release supply sources, or part names unless you want to buy them - we'll be happy to sell you an instruction kit. If you buy our product, or look at the images and figure it out for yourself, good on you. Compete with us if you like, just don't screw us, and we'll get along just fine. Big companies who might want to screw us may have more money, and more lawyers than we do, but we have more to gain by suing the pants off a big company, and believe me, we will be well motivated to do so if anyone patents our idea and claims it as their own - this is a free idea. Everybody now owns it.

Customer Comments

“Living down in Guatemala, we have quite a lot of dampness in our houses and mold is an ongoing battle. After a long dose of antibiotics due to a parasite, I absolutely required probiotics to get my gut back in order and I know homemade sauerkraut has more probiotic content than anything else I could find here. I wasn’t able to make my beloved sauerkraut or even Kombucha in my kitchen because mold would start growing immediately on the top. Your Fermenta Locks have literally been a lifesaver for me! No more mold, and PERFECT Kraut EVERY time!!! Thank you for creating such a wonderful product!!!”

“Oh how I wish I had found you first!! Too many experts and too many bucks later I discovered your “Lock” and the sheer elegance and simplicity of your system.Thank you for your help and affordability, it makes healthy food attainable.”


“I came back to order more FermentaCaps. A wonderful innovation. I have not lost a single batch of sauerkraut since I started using the original Fermenta Locks.”


“Please continue your good work on producing such a great product. I’ve tried lots of other kinds of airlocks- the 3 piece water lock, pickle pipes, fermilid, boss pickler, and I think yours is the best design and quality. I’d like to order another 100 of them right now, but I’ll have to wait a bit. I’ve had lifelong health challenges. I’m 38 and about 20 years ago my health was so bad I didn’t feel like living most of the time. Now my health is the best it’s ever been and it wouldn’t be possible without fermented vegetables, they have made a huge improvement in my health.”
