My husband and I just purchased our 1978 mountain fixer-upper, and we have entered into this process with many repair and home improvement projects on our to-do list.

Our first priority, though, (even before moving any of our belongings inside) was to remove the cigarette smoke smell.

Our house was previously a rental.

When we would walk through the door, we were met with a heavy waft of cigarette smoke, dirty-big-dogs smell, and old cooking grease. We aren’t sure how long people smoked inside our house.

The main level smelled the worst with all the wooden paneling in the living room and the oak cabinets that have been soaking up smells for years, but the basement was only slightly better.

The view makes up for all that, though, right?!

The smell made our new house feel uncomfortable and downright dirty (okay, it was actually downright dirty too).

We didn’t want to hire out the odor removal with all the other fixes we have on our list.

But thankfully, after doing our research, we were able to find some solutions for actually removing the smells ourselves instead of just masking them (and we probably saved a couple thousand dollars at the same time!)

Although it is difficult to achieve perfect results when you’re dealing with years of stuck-in smells, we are pleased with the results we have attained through cleaning, ozone treatment, and our next and final step: odor blocking primer before we repaint!

Our house feels more like a home already.

If you want to know how to deal with odor issues in your own home in true DIY fashion, I’ll show you the steps we took!

(And be sure to do your own research for your particular situation before deciding how you will treat your home!)

Pin for later!

1. Thoroughly Clean all Hard Surfaces with a Vinegar Solution

We started with a very thorough cleaning, and it took some elbow grease.

Thankfully our house has new carpet and we started out with no window treatments or upholstered items that have absorbed smells.

We would have wanted to replace or wash these types of items, if we had any.

I made a 1:1 ratio of vinegar and water in a spray bottle and used that as my cleaning solution.

Vinegar reacts with smells on a molecular level to eliminate them while also dissolving grease, grime, and any film left on the surfaces from tobacco smoke.

We found some substantial debris and grease in the bottom of some of our kitchen cabinets and under the refrigerator and oven.

There was also a lot of grime around the baseboards and lower cabinets (from dogs, maybe?), and a bit of mouse excrement…

Ew, I know, TMI.

At least I’m not going to show you pictures of those areas.

Once I cleaned those areas, I immediately noticed an improvement in the smell.

I even went so far as to scrub every kitchen and bathroom cabinet and drawer inside and out.

(We also evicted Mr. and Mrs. Mousling and their niece and nephew, and sealed their points of entry. Phew)

I scrubbed the insides of all the closets, scrubbed the walls, and mopped the ceilings. It was a lot, but it was necessary to remove that tobacco smoke film.

After the cleaning, I opened every cabinet door, drawer, and closet door in preparation for the next step.

2. Ozone Treatment

Then it was time for the real kicker, the Ozone Generator.

An ozone generator breaks down oxygen molecules in the air so they can bind to other organic molecules (that cause the odors) and change them into ozone, ultimately eliminating those odors.

Ozone generators are frequently used in rental trucks and hotel rooms to eliminate cigarette smoke smell, and they really work!

We could have rented a generator, but we ultimately chose to purchase one.

Only one local equipment rental business even had an ozone generator available to rent—we didn’t want to take a chance and not be ready to go once we closed on our house.

We also knew we would need it for a few days, plus, we can think of a few other scenarios where we will want to be able to use it again in the future.

We went with the OdorStop brand of ozone generator for a few main reasons:

  • The company is really upfront and honest about the ozone output on their generators,
  • The plates in the generator can be removed easily to clean or replace
  • Their generators are made in the USA and have a good warranty.

For the space we needed to treat, we went with their 3500 Sq Ft + UV model.

I then went to the National Ozone Association website to find out how to use the ozone generator safely and effectively.

If you use an ozone generator, I would highly recommend that you follow the guidelines on their site, as using it incorrectly or excessively can cause health problems or unwanted lingering ozone smell in your house.

You will want to vacate your house during treatment, and make sure you get all pets and houseplants out as well. Ozone is not something you should be breathing, and certain household items can be damaged by ozone if not removed from the premises.

There is no perfect way to determine the length of treatment time when every situation is different, but the National Ozone Association suggests 10,000 mg/hr for every 1,000-1,500 square feet that you need to treat.

I did the math and figured out that for our 2,000 square foot house and the 1400 mg/hr output for our generator on the highest setting, we would need to treat our house for a little over 12 hours.

That was over 6 hours for the main level and over 6 hours for the basement.

(If our generator would have had a lower output, we would have needed longer treatment times.)

We turned the generator on high with our air blower fans set up to circulate the ozone (any large fans would do), and moved the generator room by room as necessary while wearing a respirator mask.

3. Air Out the House

After the ozone treatment, we didn’t return to the house for a couple of days, and once we did, we opened up the windows to air everything out well while we were inside.

It wasn’t long before the ozone smell (which smells similar to chlorine) was completely gone.

4. Paint Last with Zinsser B-I-N Shellac-Base Primer

Our final step in this process will be applying a fresh coat of paint to the entire interior to seal in any remaining odors that will seep through the walls as time goes on.

We’ll be using Zinsser B-I-N Shellac-Base Primer in place of normal primer on our wood paneling and in difficult rooms (like our back bedrooms and bathroom) before painting.

This primer is pricey, but highly recommended by professional painters to block stains and odors. I will have to update this posts with our results using this primer when we get to that point.

(Note: I had previously mentioned in this post that we were going to use Kilz Restoration Primer. This primer also gets pretty good reviews for blocking stains and odors and is less costly, however, it seems like the B-I-N Primer is probably the top choice, so that is our new plan.)


If you’re looking to remove odors in your home yourself without hiring professional odor remediation, I hope you found this post helpful. With the right information, supplies, and equipment, you really can get decent results doing the work for yourself and save a good amount of money in the process.

I wish you the best with your home!
