Will cleaning alone get all the cigarette smell out of my apartment?

For light, short-term smoking, a thorough cleaning of the walls, fabrics, carpet, and filters usually does it. For heavy or long-term smoking, the residue sits too deep in drywall, carpet padding, and ductwork for surface cleaning to reach, so you'll typically need professional source-level treatment to clear it for good. A simple test: if the smell comes back once the place warms up or the HVAC runs, it's coming from somewhere your cloth can't reach.

Can a landlord keep my deposit over cigarette smoke smell?

Yes. A landlord can deduct for cleaning, repainting, sealing, or replacing carpet and padding that holds odor past normal wear and tear. Your best protection is cleaning well before move-out, taking dated photos of the unit, and keeping receipts for any professional odor removal so you can show the work was done.

Is professional smoke odor removal safe to do while I still live there?

Yes. Source cleaning, enzymatic and oxidizing treatments, thermal fogging, hydroxyl generators, and HEPA carbon air scrubbing are all safe for occupied spaces and around kids, pets, and electronics. We never use ozone or chlorine gas, because both are toxic and risky, and we never just mask the smell. Our methods are green and non-toxic, and we're fully insured, so you can stay home while we work.

How to Get Cigarette Smoke Smell Out of an Apartment (Renter's Guide)

Smoke · By Odor Removal Experts · Updated June 2026 · Cleveland and Northeast Ohio

If you're trying to figure out how to get cigarette smoke smell out of apartment walls, carpet, and air, you've picked one of the most stubborn odors in any rental. Cigarette smoke isn't a single smell sitting on the surface. It's thousands of tiny tar and nicotine particles that work their way into paint, drywall, carpet fibers, the backs of cabinets, and the HVAC system, then leak odor back out for months. On most jobs we walk into, the tenant has already scrubbed and aired the place out, and the smell is still there because the residue underneath never moved. That's why an open window or an air freshener never holds. This guide is for renters: what actually works, what to skip, and how to keep your security deposit.

The short answer

Cigarette smoke soaks into paint, drywall, carpet, and the HVAC, so airing out never holds. Ventilate hard, wash every hard surface with a degreasing cleaner, launder all fabrics, deep-clean the carpet, and add a carbon filter and HEPA purifier. Light smoking clears with careful DIY, but heavy or long-term smoke needs professional source-level treatment to fully remove and protect your deposit.

Why cigarette smoke smell is so hard to remove

Smoke leaves a sticky residue, sometimes called thirdhand smoke. It clings to porous and semi-porous materials and keeps off-gassing long after the last cigarette is out. Soft stuff like carpet, drapes, upholstery, and mattresses soaks it up deep. Hard surfaces pick up a yellow-brown film you can usually see once you wipe a clean cloth across them.

Here's the part people miss. Smoke moves with the air, so it gets pulled into return vents and coats the inside of the ductwork. After that the system blows the smell back out every time it kicks on, even in a room you've cleaned top to bottom. The spot we find it hiding most often is above doorframes, on the ceiling over where someone sat, and inside the kitchen cabinets nearest the smoker.

Air fresheners, plug-ins, and candles just stack a second scent on top of the first. To actually get rid of the odor you have to pull the residue out at the source and clear the airborne particles. Covering it up never works for long, which is why we never mask odors, we remove them.

How to get cigarette smoke smell out of apartment: the DIY plan

Start with a real cleaning, because pulling out the residue pulls out most of the smell. Work top to bottom so anything you knock loose lands on a surface you haven't done yet. Here's a DIY plan that holds up.

Ventilate hard. Open the windows and put a box fan in one of them facing out so it pushes smoky air outside instead of just stirring it around the room.
Wash every hard surface. Wipe down walls, ceilings, trim, doors, cabinet interiors, and the insides of closets with a degreasing cleaner, or a mix of warm water and white vinegar. Change your rinse water often, because once it goes brown you're just smearing residue back on. Watch the cloth: brown means it's working.
Launder all the fabric you can. Curtains, slipcovers, bedding, and washable clothing go through the wash, ideally twice. For things you can't launder, set out shallow bowls of baking soda or activated charcoal in closets and drawers to pull leftover odor from the air over a few days.
Deep-clean carpet and upholstery in the right order. Sprinkle baking soda, leave it a few hours, then vacuum with a HEPA filter. Only steam clean after you've cleaned, because steam can drive odor deeper and set it if there's still heavy residue in the fibers.
Handle the air and the HVAC. Swap the furnace or AC filter for a carbon-rated one, and run a HEPA air purifier with a real activated-carbon stage. HEPA alone catches particles but won't grab the gas-phase odor, so the carbon layer is the part doing the smell work.

What renters should skip or handle carefully

Be careful painting over stains. Roll paint straight onto nicotine-stained walls and the yellowing and odor usually bleed right back through within days. A dedicated stain-blocking, odor-sealing primer is the bare minimum, and even then, deep odor sitting in the drywall can keep coming through. Sealing is a step, not a cure on its own.

Skip the masking products. Plug-ins, sprays, and scented candles cover the smell for a few minutes, and once they fade the underlying odor often reads worse because your nose had reset. They also cost you time you could spend on the cleaning that actually helps.

Don't run a DIY ozone machine in a lived-in unit

Ozone is a reactive gas, and it attacks rubber, plastics, soft wiring insulation, and houseplants, and it's a respiratory irritant. It should never run with people or pets anywhere nearby. We don't use ozone at all on our jobs, because it's toxic and risky, and there are green, non-toxic methods that do the work safely. The same goes for chlorine gas, which we never use either.

Getting smoke smell out before move-out and protecting your deposit

A cigarette smell that won't quit can turn into a real deposit dispute. Landlords can deduct for cleaning, repainting, sealing, or replacing carpet and padding that holds odor past normal wear and tear. To protect your money, do three things:

Clean methodically before your move-out date
Take dated before-and-after photos of the unit
Keep receipts for any professional odor removal work

Documentation is what wins these arguments. Here's the honest dividing line we use. If someone smoked lightly near an open window over a short lease, careful DIY cleaning is often enough. If there was heavy or long-term smoking, the residue is usually too deep in the walls, carpet padding, and ductwork for surface cleaning to reach, and no amount of scrubbing the visible surfaces will get the last of it out. That's the point where professional treatment is the move that actually saves the deposit, not the one that costs you.

How professional smoke odor removal works

Pros go after smoke at the molecular level instead of masking it, and the right method depends on the surface and how deep the odor sits. At Odor Removal Experts we start with source cleaning of the residue, because no treatment can finish a job the cleaning didn't start. From there we match the tool to the problem: enzymatic and oxidizing treatments to break down odor compounds on and in materials, thermal fogging that turns a deodorizer into a vapor so it travels the same paths the smoke took into hidden gaps and porous surfaces, and hydroxyl generators that are safe to run in occupied spaces while they neutralize airborne odor.

We pair that with HEPA and activated-carbon air scrubbing to pull particles and gas-phase odor out of the air, and we seal porous surfaces when the drywall or framing is holding odor that cleaning can't fully reach. We never use ozone or chlorine gas, because both are toxic and risky, and we never just cover odors up. Everything we use is chosen to do the work without putting your household at risk.

Our methods are green and non-toxic, safe around kids, pets, and electronics. Most jobs wrap in 1-4 hours, with same-day or next-day availability, and the work carries a 100 percent guarantee: if the odor isn't gone, the job isn't done. Technicians are uniformed, fully insured, and discreet, which matters when you're dealing with a landlord or a building front desk. We serve Greater Cleveland and Northeast Ohio.

What professional smoke removal costs

The honest answer is there's no single price, and you should be wary of anyone who quotes one sight unseen. Cost comes down to a handful of real factors, and a quick walk-through is what gives you an accurate number.

The size of the apartment and how many rooms are actually affected.
How heavy and long-term the smoking was, since that sets how deep the residue goes.
Which surfaces are involved, because carpet, padding, and HVAC take more work than bare painted walls.
Whether sealing or more than one treatment method is needed to finish it.
How fast you need it, like a rush job ahead of a move-out inspection.
