Quick Takeaways

Vacuum: Always start by vacuuming your sofa to remove dirt and debris that can contribute to odors.
White Vinegar: Use for neutralizing odors on non-removable fabric covers or for washing removable covers.
Baking Soda: Best for absorbing odors from the sofa’s surface, especially in high-use areas.
Activated Charcoal: Ideal for long-term odor absorption in well-ventilated areas, but avoid direct contact with the sofa. It also helps absorb moisture to prevent mildew.
Ozone Machine: Use for strong, persistent odors, but only when the room can be ventilated, and no one is present during the process.
Steam Cleaning: Effective for tackling stains and stubborn odors caused by dirt buildup.
Air Fresheners: A quick, temporary solution when you’re in need of immediate relief.
Leather Conditioner: Use specifically for leather sofas to clean and neutralize odors without damaging the material.

Check the Cushions and Identify the Source of the Odor

Look for stains, spills, or trapped moisture in the cushions, seams, or fabric.
If you don’t find any visible stains, check areas that are used heavily, such as the seat cushions, armrests, and the back of the sofa. These spots can accumulate oils, sweat, and other residues that cause odors.
Knowing the exact source will help you choose the most effective cleaning method and prevent odors from returning.

Check To Cushions To Find The Odor Source

Vacuum Thoroughly

Use the upholstery attachment to vacuum all areas of the sofa, including underneath the cushions and along seams.
If the cushions and pillows are removable, take them off the sofa and vacuum both the cushions and the sofa frame separately. This ensures a more thorough cleaning and removes dust, dirt, and debris from hidden areas that can contribute to the odor.

Directly Machine Wash Removable Covers

For removable sofa cushion covers, machine wash them in cold water with one cup of white vinegar to eliminate odors and bacteria. This helps freshen up the covers and remove any trapped moisture or odors caused by daily use.
Be sure to check the care label on the sofa cover to ensure it’s safe for machine washing.

Apply Baking Soda

Sprinkle a generous amount of baking soda over the entire sofa, including the cushions and armrests.
If the sofa covers are washable, you can also sprinkle a light layer of baking soda directly on the inner cushion and gently pat it in. This helps to absorb odors deep within the cushions.
Let the baking soda sit for 15–20 minutes, then vacuum it up. It will help absorb odors and leave your sofa smelling fresh.
Repeat if needed, especially in areas with stubborn smells.

Spray White Vinegar on Non-Removable Fabric Covers

For non-removable fabric upholstery, mix the following solution in a spray bottle and lightly spray the sofa:

For fabric upholstery: Mix 0.5 cups (120 ml) white vinegar, 0.5 cups (120 ml) rubbing alcohol, and 1 cup (240 ml) of water.
For leather upholstery: Mix 0.25 cups (59 ml) white vinegar and 0.5 cups (120 ml) olive oil in a spray bottle.
For synthetic upholstery: Mix 0.5 cups (120 ml) white vinegar, 1 cup (240 ml) of warm water, and a splash of dish soap in a spray bottle.
Optional: Add a few drops of lavender essential oil or lemon juice to freshen the scent. Shake the bottle well before spraying.

If you prefer a ready-made solution, store-bought deodorizers like Febreze can work on most couch materials, except for suede and leather.

Water Vinegar Spray For Sofa Deodorizing

Use Activated Charcoal

Activated charcoal is excellent for absorbing odors from fabric and the air. It works well for both short-term and long-term odor management.
To maximize its effectiveness, remove the cushions and place charcoal bags in the corners of the sofa, where odors tend to accumulate. This will help absorb even the most hidden sources of smells.
In addition to odor absorption, activated charcoal also helps absorb excess moisture, preventing mold and mildew growth in your sofa.
Important: Do not let the charcoal come into direct contact with the sofa, as it could stain the fabric. Make sure the charcoal bags are placed in a well-ventilated area where they can efficiently trap odors and moisture.

Use an Ozone Machine (With Caution)

Ozone machines are a powerful cleaning tool that releases ozone to break down odor-causing molecules in the air and on surfaces. However, they should be used with caution as ozone can be harmful in high concentrations.
Place your sofa in a large plastic bag or in a room where you can leave the ozone machine running.
Once the machine is turned off, leave the room and allow the space to ventilate for at least 30 minutes. For best results, wait at least an hour before re-entering the room. This ensures that the ozone has dissipated and the air is safe to breathe.
Important: Never use an ozone machine while people or pets are in the room, as high levels of ozone can be harmful.

Steam Clean for Stubborn Odors

Steam cleaning can effectively remove dirt and sanitize your sofa, especially when odors are caused by stains.
Use a steam cleaner with an upholstery attachment, following the manufacturer’s instructions.
Always spot-test the fabric to avoid any damage before steaming the entire sofa.

Air Fresheners for Quick Relief

If you need a fast solution, use an air freshener to mask odors temporarily.
Lightly spray an air freshener designed for fabric, and let it dry. While this works in a pinch, it’s best to pair it with more thorough cleaning methods for long-lasting results.

How to Remove Odors from Leather Sofas?

White Vinegar: Vinegar is especially effective for neutralizing smoke or musty odors on leather. Simply mix a small amount of vinegar with water and use a soft cloth to wipe down the surface. While the leather may smell like vinegar briefly after cleaning, this odor will dissipate quickly.
Baking Soda: Another option is baking soda. Gently shake a small amount of baking soda over the affected area and let it sit for 15–20 minutes. It will absorb the odor and leave your leather sofa smelling fresh.
Leather Conditioner: If the odor persists, use a specialized leather conditioner designed to neutralize smells without damaging the leather. Be sure to follow the manufacturer’s instructions for best results.
