11 Everyday Uses for Nok-Out—the World’s Best Odor Eliminator

Nok-Out and I met quite by accident. While searching for ways to deal with offensive odors—that musty smell of an old book or the stench of pet urine—we found each other online. Twenty years later I’m still convinced that there’s just nothing else like the amazing product called Nok-Out.

Nok-Out eliminates odors scientifically through a process known as oxidation. Nok-Out is completely non-toxic, contains no chemicals or fragrance and no odor of its own. It is safe to use in the kitchen and around children because it is harmless to humans and animals.

I’ve used Nok-Out and now its companion SNiPER continuously in my home since then and have recommended it to readers facing serious and potentially expensive odor issues. Thousands of people have reported back how Nok-Out has saved the day on more than a few occasions!

In the beginning, I hoarded my precious gallon of Nok-Out, somehow assuming that I must save it for serious, super smelly situations. After all, one just never knows when oh, let’s say a skunk might wander into the house, become startled, and then do what skunks are known to do. Or the power goes out while you’re on vacation and the freezer turns into a big nasty garbage dump. Or pet odors, sick rooms, mold and mildew, and any number of other smelly situations.

I don’t hoard my Nok-Out anymore since I’ve learned how useful it is, not only for major challenges but to maintain a safe, sweet-smelling, sparkling clean home.

I keep a spray bottle handy filled with a 50/50 dilution* of Nok-Out and water under the kitchen sink. And I reach for it often, keeping in mind that for Nok-Out to work, it must reach the source of the odor or contamination and then sit undisturbed for 5 to 15 minutes or until dry. It is during that time that the odor becomes oxidized and then vanishes.


1. Mattresses and pillows

Every week when I change our bed linens, I spray the mattress and pillows with Nok-Out (my trusty 50/50 dilution in a spray bottle). It’s a routine that has kept our mattresses and pillows fresh and clean smelling without any tell-tale fragrance.


2. Refrigerator

I don’t know what it is about refrigerators (maybe the food?!), but no matter its age, a refrigerator can quickly turn into a stinky place. An unnoticed milk spill, a tiny leak from meat, poultry, and fish, and in no time at all the thing gets smelly.

Cleaning those spills with baking soda or dishwashing detergent is a good idea, but doesn’t always take care of the problem. But doing that with Nok-Out is a surefire way to eliminate every hint of odor. I spray every square inch of every surface, even into the vents. And I use Nok-Out to clean the outside water and ice dispensers, too.

3. Shoes

Oh my, yes. Shoes! I routinely mist the inside of our shoes and boots with Nok-Out. No more stinky shoes. And I like knowing that I’m not burying odors—I’m forcing odors to first neutralize then vanish in the simplest but most effective way.

4. Trash cans

I keep my Nok-Out spray bottle with me when I empty trash cans and wastebaskets, giving each one a misting before replacing the plastic liner. I do the same for the inside of the trash container cabinet in the kitchen and the big cans in the garage.

5. Sink overflow and drains

You know that little overflow hole in most bathroom sinks? I spray Nok-Out into it because I’ve discovered that over time, it can get smelly in there. Check yours to see if I’m not right about that. I spray into the drains, too.

6. Storage

I figure that anything that is packed away in storage—seasonal decorations, books, toys, bedding, clothes, etc.—is prone to developing a funky smell, especially if you live in an area prone to high humidity. A fine mist of Nok-Out when bringing things out of storage takes care of that in short order.

7. Cutting boards

A wooden cutting board is the most beloved but also the most polluted thing you use daily. After cutting up vegetables, fruits, meats, or seafood, wash with soap and warm water. Dry thoroughly then spray with Nok-Out. Do not disturb for 5-15 minutes. Now it’s good to go until you chop meat again.

8. Car interior

Want to get rid of that funky odor in the car? Nok-Out! Lightly mist every surface—leather and cloth upholstery, the headliner, doors, carpet, floor mats, console, dashboard, all of it—even into the ventilation system.


9. Litter boxes

If you have cats you need Nok-Out to clean those boxes and then remove odors in the areas around them. If there’s an odor, you’ve got more than a bad smell—we’re talking bacteria and nasty germs, too. Empty the litter, wash the box with soap and warm water. Dry thoroughly then spray with Nok-Out. Do not disturb for 5-15 minutes. Now that box is fresh and clean, ready to be refilled with fresh litter.


10. Washer gasket

When I’m done with the laundry for the week, I open that big rubber gasket on my front loading machine and use a microfiber cloth to soak up all of the water that remains in there. Then I hold it open and spray it well with Nok-Out, leaving the door open for a few hours to allow it to dry. No more odors.


11. Sofa and chair cushions

Yep, I mist all the upholstered furniture in our house with Nok-Out—not every week, but every time that I vacuum the upholstery.

    Hi Mary, I just had to add, that I did call the 866 number a few years ago and who ever I talked to was extremely helpful!!!! xoxo

  2. marlene merrill says:

    Hello Mary!!!! I bought Nok-out and Sniper after reading about it on your column. This stuff is INCREDIBLE!!!!!! I had a fridge that just died on me. (a beautiful large side by side) I emptied it out and closed the doors. Oy what a smelly mistake!!!! LOL. The smell was horrible. I sprayed the entire insides and drawers with either the Nok-Out or Sniper and that smell was totally gone!!!! Even used it on things that smelt moldy. Thank you for the great advice, can never go without these products ever!!!!

  3. lee says:

    is the nok out on amazon just as good a product as the nok out you refer to. the bottle looks the same but just wondering if the formula is the same. Thank you

  4. Martha Heagany says:

    Hi Mary….it’s me again…hope you’re well.
    question….so I just purchased (via YOUR link… yeah!) the 16oz spray bottle of Nok Out..is this what I want to split 50/50- or do I use it as is? My mom has had radiation and the bacteria smell is awful on sheets/ blankets etc. so I gather this will work. MY QUESTION…can this be used on skin??? Would love to remove the bacteria order on her skin…but a bit nervous? Many thanks. Stay well.

    • Mary Hunt says:

      Yes you can dilute the product that comes in the 16-oz bottle with sprayer attachment. You’ll need a second bottle or container to create that 50:50 dilution. Nok-Out is not toxic or harmful to humans or animals. As for applying it to one’s skin, I am going to refer you to Ted at Nok-Out. I’m hesitant to give specific medical-like advice. You can call 866-551-1927 to speak directly with him.

  5. Gina Stevens says:

    I’ll take you up on the tip to use 50/50 Nok-Out/Water in a spray bottle to squirt the trash cans. Thanks Mary!

  6. Jacqui says:

    I have two issues that I’ve tried Nok-Out on that I have not had success with. I have a metal thermos with a silicone seal in the lid that has a permanent coffee creamer odor to it and my Instant Pot silicone seal has a permanent cumin smell. I have soaked both in full-strength Nok-Out for days to no avail. Do you have any recommendations? And thank you for all of your advice and handy tips & tricks. I love your website!

    • Mary Hunt says:

      Bake that Instant Pot silicone seal (the thermos one as well if it is removable) in a 250F oven for 45 – 60 minutes. That’s the best way to kill the food odors it absorbs! Then I suggest you purchase a second seal to be used for desserts and non-savory recipes. Thanks for your kind words, Jacqui!

      • Jacqui says:

        Thank you Mary. I appreciate you taking the time to respond and always for the great advice! I’m going to bake some silicone. Blessings!

    A few years ago, my daughter returned from NY state to VA (about a 7 hour trip) with her cat in our van that had velour seats. When she got home, the van reeked so bad from the cat urine and spray that you couldn’t open the door…it was absolutely disgusting. I used the Nok-out on the seats (I had read that they needed to be soaked). I did the best I could and the next day…ALL odors were gone. I’m not kidding you…it was unbelievable.

  8. Barbara J Pire says:

    I am so happy that you turned me on to Nok Out and Sniper! I have a gallon of each they are awesome. Example of my dog got sprayed by a skunk years ago (before Sniper came out) and I had to go to work that morning. Well I sprayed Jesse head to toe with straight Nok Out and rub it in with a towel and when he was dry NO MORE SKUNK SMELL!!! I have moved since and am not by the woods but all of my neighbors that their dogs got sprayed would ask me for a spray bottle of Nok Out. I love both Nok Out and Sniper!!!

  9. Angela F says:

    Do you think if I combined Nok-Out with hot water in my carpet cleaner after shampooing, it would eliminate any pet urine residue/smell that the shampoo didn’t get?

    • Mary Hunt says:

      Yes with this caution: Nok-Out should not be heated so add it to room temperature water. And I would add to lightly extract, because you need the Nok-Out to remain for at least 15 mins and then air dry. That might be tricky because you don’t want to leave carpet overly saturated for a long time.
