How to Eliminate Stubborn, Horrible Household Odors—Pet, Smoke, Mold, Mildew

I love the smell of a campfire mixed with the scent of pine trees on a cool summer night. But stale cigarette smoke odor in a car or apartment; or the smell of an old house fire? That’s different and a problem my dear reader Lisa is finding to be anything but pleasant.

Help! I have a chance to go back home—to buy the home I grew up in. In the years since I’ve lived there, the house has had a fire so there is smoke damage. Can you recommend something we could use to get the smoke smell out? We are tearing out all the damaged wood from the home but still we have the smoke odor.

I’m curious to know if Nok-Out, the product that you talk about often, would work to eliminate that odor. I appreciate your column and enjoy reading it each day. Love, love the tips and use them often. Thanks so much. You have blessed my life in so many ways. Lisa


Good news for Lisa (and many thanks for her kind, encouraging words)! Yes, without a doubt, Nok-Out will eliminate the smoke odor and every other kind of odor Lisa—or you—may be dealing with.

The science

Unlike supermarket room fresheners that do little more than try to cover up odors with fragrance, Nok-Out is an “oxidizer.” When it comes into direct contact with the source of the odor, it oxidizes that smelly stuff, changing it into something that no longer has an odor—pure oxygen. But it can only do this when it comes in direct contact with surfaces that have been touched by the stinky stuff, be that an entire room, a garbage can, or a teen’s shoes.

Cool mist

The cheapest and most effective way to get Nok-Out to every surface in a room that the smoke has touched—even those areas that may be inaccessible, is with an ordinary household humidifier that delivers cool mist. Then wait for the simple science that makes Nok-Out work. Results will not be instantaneous.

Prepare for the oxidation process to give off its own odor in some situations, as the smoke smell gets elimiinated. I’ll tell you now during the process of oxidizing the offensive odor, it’s going to smell like a stinky swimming pool with a hint of chlorine. Don’t be surprised by this. It’s part of the process. Just wait.

Sweet smell of nothing

Once the oxidation is complete you’ll be left with the wonderful smell of—nothing! The odor will be gone and it will not come back. Just know that depending on the severity of the situation you are dealing with, this could take days, not only hours.

Dispense with a humidifier

The Best Inexpensive humidifier for this purpose—when an entire room or large area has been penetrated by the smoke and it is nearly impossible to hand-spray Nok-Out in order to touch all of the areas— is a cool mist room humidifier like this Honeywell model. Its large capacity allows it to run for many hours between fill-ups.

Large, closed areas

To eliminate old and persistent smoke odor in a room or car, first spray Nok-Out full strength in the corners, cracks, baseboards; on door-jams and casings.

In a jug or other large container, pour 1 cup  (8 oz.) Nok-Out and one-gallon room temperature tap water. Use this to fill the humidifier. Operate it in the room as needed with all windows and vents closed for up to four hours at a time.

    I washed a load of clothes that had my favorite black gym pants in it. I forgot about them and left the whole load in the washing machine overnight. When I got them out the next day, the pants had that soured smell to them. I was so disappointed! I tried washing them several more times but could not get the smell out. Then I remembered my Nok-Out. I sprayed it full strength on the pants and washed them and the smell was not as bad so I washed them again and it took it out completely! I am totally sold on this product!
