How To Remove Odor from Concrete,
Tile or Brick with Nok-Out or Sniper
Even When Sealed, Concrete, Tile, and Brick are Like a Big Hard Sponge
It may be urine odor on a hot summer day. The dog has been peeing on the concrete slab by the back porch and now that it is summer, it is starting to stink. Or maybe it is something that spilled and now smells horrible. Concrete, tile, brick and grout can get to be really stinky. With Nok-Out, you can remove odor from concrete or other hard floors successfully, even when everything else you have tried failed.
Concrete is a strong, durable, and easily cleaned semi-porous surface. This material is actually very much like a big hard sponge–it absorbs odors, even if the concrete has been sealed. These odors may come from pet urine, oil spills, food spills, mold, mildew, and many other odor problems. Brick, some tile and grout also absorb odors deep into the pores, making it difficult to remove. With Nok-Out, you can permanently get rid of odor in concrete, tile, brick or grout.
Treating Odors in Concrete Flooring Without Grout
Bear in mind that our products are oxidizers and do their work when they come into direct contact with the odor source. When contact is achieved, that stinky stuff is oxidized, changing it into something that no longer has an odor. Often, that stinky stuff has entered and filled the pores in the grout, tiles or concrete. When you initially treat it, Nok-Out (or SNiPER®) will successfully remove the odor from the surface, but the pores may be so full of stinky stuff that Nok-Out literally cannot get in there and make direct contact, so there may be some small amount of odor remaining. Wait a couple of days, however, and that stinky stuff that has filled the pores will literally rise to the surface, where a second application will remove it as well. (This is diffusion at work!) Follow these guidelines to successfully remove odor from concrete, tile, brick and grout.
- Spray, or pour Nok-Out onto the flooring. Gently agitate with a broom or brush. You are trying to encourage penetration into the concrete with this step.
- Spray Nok-Out into corners, along baseboards, under boxes, furniture, game tables, etc.
- Using a sprayer with a fine mist, spray the air and ventilation system in this area.
- Allow to air dry for up to 24 hours.
- Re-treat, if necessary. You may dilute Nok-Out with water in a 50/50 ratio for this step.
REMEMBER: Sniper® and Nok-Out are oxidizers and only do their job when in direct contact with the source of the odor.
Direct contact with ALL of the stinky stuff is essential to remove odor from concrete, tile, brick or grout permanently.
Remove Odor on Grouted, Hard or Porous Surfaces:
- Follow steps 1, 2, 3 above
- Take a stiff brush, apply Nok-Out, and briskly rub grout, paying special attention to areas where you know contamination exists.
Allow to air dry naturally. Re-spray Nok-Out without brushing.
- Allow to dry for up to 24 hours.
- Remember that diffusion will take place. Wait several days and if odor has returned, this is the stinky stuff rising up out of the pores.
Another treatment will take care of it and you should be done.

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. 😊👍⭐️
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!
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!
Cats Get Old!
Cats get old. Things happen. Nok-Out was recommended to me by a friend in another state. I Will never go to the pet store again to try any other product. Nok-Out is IT! I told my Veterinarian about it. I love how fast it arrives after ordering. I ordered three times because we are still working on issues, but at least the house doesn’t SMELL! Amazing product. THANK YOU!
Nok-Out Removed Old Dog Urine Odor
I have an Electrolux rug shampooer and was trying to remove old odors of dog urine in my oriental carpets. I shampooed them then put a concentration of 4-1 water to Nok-Out in the tank and went back over them. No more odor!! Worked great! Was sooo happy!
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.
“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!

I learned about Nok-Out from Mary Hunt’s Everyday Cheapskate column and had to try it. Shipping was so fast and your customer service is OUTSTANDING! I am amazed at the results!

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.
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.
Rotten Potato Smell Gone!
There cannot be anything worse than potatoes that are forgotten and rot. Any pet I have ever had that had an accident cannot compare. Nok-Out eliminated the odor quickly. What a wonderful product!
