How to Get Weed Smell out of an Apartment
12.07.2026
To get weed smell out of an apartment, open every window you can, run a fan blowing air outward, and wash the fabrics that trapped the smoke: curtains, throw blankets, couch covers. Wipe hard surfaces with a degreasing cleaner, empty ashtrays and trash outside, and set out bowls of baking soda or activated charcoal to absorb what lingers.
What you'll need
- A box fan or any fan you can point at an open window
- Baking soda and, if you have it, activated charcoal
- A degreasing all-purpose cleaner and microfiber cloths
- Your washer, or a trip to the laundromat, plus laundry detergent
- A fabric refresher spray or a spray bottle of water with a little white vinegar
- Trash bags you can carry straight out to the hall chute or bins
- An upholstery-safe cleaner for the couch (check the tag first)
Step by step
- Move the air out. Open every window that opens and put a fan in one of them facing outward. That pushes smoky air into the street instead of just stirring it around. If only one window opens, crack the apartment door to the hallway to create a path.
- Deal with the source. Empty ashtrays, grinders, and any trash holding butts or roaches into a bag and carry it out of the unit now, not later. The smell keeps refilling the room as long as the source sits there.
- Wash the soft stuff. Smoke settles into fabric. Strip curtains, throw blankets, pillowcases, and removable couch covers and run them through the wash. These hold more odor than any surface in the room.
- Wipe the hard surfaces. Smoke leaves a thin, sticky film on walls, cabinet fronts, the inside of window glass, and light fixtures. Go over them with a degreasing cleaner and a microfiber cloth. In a small apartment this makes a bigger difference than people expect.
- Treat the couch and rug. Sprinkle baking soda over upholstery and carpet, leave it a few hours or overnight, then vacuum it up. Spot-test an upholstery cleaner on a hidden seam before doing the whole cushion.
- Absorb the rest. Set bowls of baking soda or activated charcoal on shelves and near the couch. They pull residual odor from the air over a day or two while everything airs out.
- Finish with a light mist. Once surfaces are clean, a fabric refresher or a light vinegar-water mist on aired-out upholstery helps. Don't drench anything.
What NOT to do
Don't just spray air freshener over the smell. It layers perfume on top of smoke and fades in an hour. Don't scrub painted walls with an abrasive pad or a strong solvent, especially in a rental. You'll cut through the paint and owe your landlord a repaint. Don't soak a fabric or microfiber couch with water or vinegar. It can leave rings and mildew, and some upholstery is marked "S" for solvent-clean only. Keep liquids off your steam radiator and its valve. Don't burn incense to cover the smell near a smoke detector, and don't block a non-opening window's trickle vents thinking that traps odor. It just traps it in with you.
When to call a pro
DIY handles a session or two of smoke in a room you use. But if the smell is baked into a unit after months of smoking, has soaked into the carpet padding and behind the walls, or you're trying to get a security deposit back before a move-out inspection, home methods hit a wall. Smoke residue on high ceilings, inside HVAC returns, and deep in upholstery often needs equipment and time most renters don't have. If you're at that point, book apartment cleaning with CleanWhale and let a crew do the deep pass.
FAQ
How long does weed smell take to leave an apartment?
Fresh smoke from one session usually clears in a few hours with windows open and a fan running. Odor that has settled into fabric and walls can take a couple of days of airing out, washing, and absorbing with baking soda before it's gone.
Does baking soda actually remove weed smell?
Baking soda absorbs odor rather than masking it, which is why it works on couches, carpets, and open air. It won't fix smoke ground into walls on its own, but as part of washing fabrics and wiping surfaces it makes a real difference.
How do I hide the smell from my landlord or neighbors?
The honest answer is you clean it out rather than cover it. Wash fabrics, wipe surfaces, and air the unit. A towel along the bottom of your door slows smoke from drifting into the hallway during a session.
Will the smell come back after I clean?
Only if the source stays. If you removed the butts and trash and washed what held the smoke, it won't return on its own. Residual odor from deep in upholstery or walls can resurface in humidity until it's fully cleaned.
