How to Remove Urine Odor With Nok-Out

Remove Urine Odor

Nok-Out is Your Go-To Solution For This Problem

Urine mishaps happen. Consider that there are medical issues, pet problems, children in the home, elderly parents. No matter how it happens, if pet or human urine odor is a smelly issue in your household, turn ‘stinky’ into ‘smiley’ with Nok-Out. This non-toxic all-purpose cleanser is a game changer if you have smelly urine issues. It doesn’t matter if it is dog urine, cat urine, people urine or any other kind of urine. As long as you can get Nok-Out to come  in to direct contact with the source of the odor, you can easily remove urine odor with Nok-Out or SNiPER.

Note: As you read through these instructions, remember that Nok-Out is an oxidizer and when it comes into direct contact with something smelly, it ‘oxidizes’ (think changes) that smelly stuff into something that no longer has an odor. As an oxidizer, Nok-Out can only make this change happen if it is in contact with the smelly stuff. Direct contact with all the odor source is required for Nok-Out to be able to successfully remove urine odor.

Medical Issues

Bedridden people occasionally soil their bed. If a mattress or some upholstered furniture stinks of urine, apply Nok-Out as follows to remove urine odor:

  • Spray the mattress heavily on all sides with full strength Nok-Out. Dry quickly by using fans, or opening windows. Reapply on heavily contaminated sites. In padding, liquids wick into the nearby stuffing, even if is a synthetic material. Remember Nok-Out is working whenever it reaches the site of an odor. Wash all linens and contaminated clothing regularly with Nok-Out. (See dilution rate below.) Reapply Nok-Out to a mattress as quickly as you notice new dampness. This is how you stop the urine odor from happening!
    • In the case of furniture, remove any pillows, (If washable, launder with diluted Nok-Out. See dilution rate below.) Spray the upholstered fabric underneath, and sides, as well. Using an overhead fan and opening windows speeds the drying process. Nok-Out begins to work immediately, as it dries. Because the padding is thick and massive, this step may take several applications especially if urination has been frequent and hasn’t been treated with Nok-Out.
    • Spray your hands often with Nok-Out. It cleans and helps prevent pathogens from being passed on!
    • Spray the air after you have cleaned the mattress or other furniture. Use Nok-Out straight from the bottle to decontaminate and cleanse the air.

    Children’s Accidents

    As a teacher once told me, “Some children simply become too focused, are too engaged with an activity, or basically don’t feel the urge to urinate until it is too late!” From the beginning, babies and children are encouraged to urinate or defecate on the toilet. During toilet training, accidents simply happen! During this process, Nok-Out really is a mom’s best friend.

    Always wash children’s clothing in Nok-Out (See dilution ratio below).

    Spray tiny hands (and yours too) with Nok-Out. Air dry if possible, or use a fresh towel to wipe. Nok-Out is non-corrosive and non-abrasive and will not cause harm to the delicate skin of babies – nor yours.

    Spray the toilet bowl, toilet seat, floor with Nok-Out. More complete directions can be found at

    Clean any sites which may be urine-contaminated with Nok-Out. The sooner you discover and spray with Nok-Out, the quicker the odor is gone!

    Nok-Out is safe to use on skin. If a diaper rash occurs, spray Nok-Out (dilute 1:1 with filtered water and spray lightly on the skin. Allow to dry, and use your favorite healing ointment to speed healing.

    Spray all plastic toys with full-strength Nok-Out. Wash stuffed toys with Nok-Out. Nok-Out is “a must” for day-care facilities!

    Pet Urine Odor

    Litter box odor removal:
     Discard old litter. Wash box with warm soapy water, and rinse well. Spray the bottom and sides of the litter box with Nok-Out and allow to air dry for a few minutes. Replace litter. Spray the litter heavily with Nok-Out. (Cats will dig around after using the box, and will mix Nok-Out into the whole litter material.) Every day, remove clumped litter, and spray the box all over, inside and out with Nok-Out.

    Pet urine odor in dirt:
     When soil is dry, take a hand garden fork and begin disturbing the dirt down about 2 inches. Spray with full strength Nok-Out. Replace soil, and spray the surface heavily with Nok-Out. Let dry naturally.

    A crawl space under your house is a great place for wild animals to hide. Unfortunately, they urinate there too. You can remove urine odor in dirt easily. Apply Nok-Out using the method above, dig about 1 foot outward from the contaminated site. Dig about 2 inches into the contaminated site. Spray the entire area, let dry. Replace the dirt and disturb it before heavily spraying the topsoil. Nok-Out will not prevent animals from revisiting the site. Research online for ways to deter a return visit.

    Wood, Laminate, Tile, Linoleum, Granite, and Concrete Surfaces


    Clean the surfaces with Nok-Out, using a dilution rate of 50/50 with water. When dry, spray a stream of full-strength Nok-Out onto grout between tiles, using a soft toothbrush, scrub Nok-Out into the tile. Dry completely. If any remnant of odor remains, or if it reappears later, reapply as above. If odors have gone deeply into the grout, they will surface in a day or two, whereupon you can spray again into the grout. Even old urine odors will be neutralized permanently by Nok-Out.

    Other Hard Surfaces:

    Laminate or natural wood flooring, linoleum or terrazzo flooring are somewhat easier to clean. Mop or sponge full-strength Nok-Out on all flooring. Pay particular attention to corners, under cupboards, around baseboards. Cats have a habit of spraying baseboards, and about three inches above. If urine odors come from the wall, such a porous surface may require more than one application, but you will find success immediately, and completely by following these directions.


    Is like a big hard sponge and it definitely absorbs urine deep into the pores where it is difficult to clean away. This can turn into a truly stinky problem when the concrete is part of you back porch slab and the heat of summer is upon us!  Pour or spray Nok-Out liberally on the concrete. Use a broom to spread the Nok-Out around evenly and to provide gentle agitation.  Allow to air dry.  This will clean the surface of the concrete, but most of the time, there will be residual stinky stuff deep  in the pores of the concrete. After 3 to 5 days, that stinky stuff will literally begin to rise out of the pores (Who would have thought that diffusion would work in concrete – but it does!).  For more detail about how to remove urine odor in concrete, see “Concrete, Tile and Brick Odors“.


    Carpets, Rugs and Urine Odors

    Carpets present a bit of a challenge because Nok-Out MUST come into direct contact with all of the stinky stuff to be able to do it’s job. With carpets, you have the fibers on top presenting you with a tremendous amount of surface area, the mat backing, perhaps a mat cover, the pad below that and finally, whatever flooring you have at the bottom. If urine has sunk down through those layers, then Nok-Out too, must go down to where the odor source lies. For full instructions, see: Remove Odors From Carpet. For rugs, see: Area-Rug Cleaning with Nok-Out.  If you have a home carpet cleaning machine, Nok-Out can work in it just fine and that is a great way to spread Nok-Out evenly throughout your carpet.  See the blog article, “Want to Use Nok-Out or SNiPER in your home carpet cleaning machine?

    In Conclusion

    Urine odors can be painful for all involved. Fortunately, Nok-Out can remove urine odor on contact. If you follow these instructions carefully, it works, every time!  Buy some today so you’ll have it on hand when you need it most!

    Sniper Eliminated Our Mold Problems!

    We’ve used SNiPER disinfectant for several years. It works great. It has eliminated our mold problems and, still, we use it to keep our wooden cutting boards safe.

    Completely Eliminate a Horrible Smell

    Mary Hunt introduced me to Nok-Out years ago and I am still amazed at how it can completely eliminate a horrible smell.

    Yesterday I hosed some dust off a plastic laundry basket. I left it outside to dry for a bit and then returned it to the garage.

    A few hours later I walked into the garage and the entire place reeked of cat pee! I did not realize that the neighborhood tom cat had come by and sprayed my basket. It was so bad that I was ready to trash it, but I thought I would try to spray it down with Sniper first. I doused it liberally and left it overnight. Ta Da! Absolutely no smell this morning!

    Even after all these years, I am still amazed every time your product works on a smell as terrible as cat spray!

    Thank you, Ted!

    “Nok-Out Saved My New Car!”

    Thank you for creating such a great product. I would and will recommend this to everyone I know. My son left raw meat in my car for 4 days and I thought that my new car was ruined, but after talking with you and using the product, I can now get in my car and the only thing that I smell is a clean, disinfected smell! Thank you for saving my new car!

    Rotten Potato Smell Gone!

    Removed All The Feral Cat Urine

    Sniper has been AMAZING. I was able to completely remove all the feral cat urine scent from the carpets, mattresses, clothing, and toys. It worked beautifully and left no smell, no fumes, and didn’t leave any discoloration. Sniper is now my cleaner of choice and I use it everywhere to clean and sanitize as well as freshen the air. I even use it in my daughter’s gym shoes and soccer bag. Thank you so much. Seriously the best product on the market.

    Sniper Removed Old Water Odors, Mold & Mildew

    I have been using Sniper in the Offshore oil industry as both a disinfectant and a deodorizer for years. It has eliminated old water smells of toilets and bathrooms not used in a year where the water sat and molded mildewed and stank. As well as being injected into our old quarters ac vents to prevent mold buildup. Always worked better than anything comparable and well worth the price.

    Christmas tree and Raggedy Ann

    We have an artificial Christmas tree that’s still gorgeous but old. Putting it up always bothers my asthma and irritation from getting scratched is not pleasant. Last year I sprayed the tree and the “old tree” smell disappeared. I had purchased Sniper on Mary Hunts advice and it really took care of the basement (moldy) smell! Great! My daughters vintage dolls with cloth bodies had spots of mold or mildew, these are dolls my grandchildren play with. Oh my goodness! Sprayed the doll’s bodies and yarn hair, and the next day they all smelled great, moldy spots gone ! These dolls were over 30 years old and now look soooo good! Would recommend Sniper for other uses, too. Doggy rug smells gone! Smelly shoe odors gone. Grateful to Mary Hunts column for letting us know. 😊👍⭐️

    My Mildew Stain Disappeared!

    I brought in the plants for winter and when it was time to move them back outside in the spring, I had a mildew stain on the carpet. I received my Nok-Out Carpet cleaner and sprayed the stain and let it sit for 10 minutes. When I returned to scrub the stain it was completely gone!! Woo hoo!! Thank you, Mary Hunt, for introducing me to this wonderful product!
