If your mattress has been exposed to smoke from a fireplace, it can retain odors, soot, and residue that are difficult to remove without proper care. Smoke particles are tiny and can penetrate deep into the fabric and padding, making it essential to act quickly and methodically. Begin by taking off all linens—sheets, pillowcases, and any mattress covers and wash these items separately using the hottest water safe for the fabric and a strong detergent. Toss in half a cup to a full cup of vinegar to dissolve smoke-based residues.

Next, vacuum the mattress thoroughly. Opt for a vacuum equipped with a soft-bristle upholstery tool to cover every inch paying special attention to seams, crevices, and any areas where soot may have settled. Clean or replace the collection system immediately to stop residual odor from re-depositing. A HEPA-equipped vacuum is ideal for trapping microscopic smoke debris.

After vacuuming, sprinkle a generous layer of baking soda over the entire mattress. Baking soda acts as a powerful, non-toxic odor magnet for smoke residues. Make sure to cover the surface evenly, including the sides if accessible. Let the baking soda sit for at least eight hours, or overnight if possible. For stronger odors, you can leave it on for up to 24 hours.

Once the time has passed, vacuum the mattress again to remove all the baking soda. Use multiple passes, especially along seams and edges, to guarantee complete removal. If the smell persists, you can lightly mist the mattress with a solution of equal parts water and white vinegar. Do not soak the mattress—just spray a fine, even layer. Allow it to air dry completely before using. Use box fans or ceiling fans to circulate air around the mattress. Avoid using the mattress until it is fully dry to prevent mold or mildew.

If there are visible soot stains, you can gently dab them with a damp cloth and a small amount of mild dish soap. Never rub or scrub aggressively—it risks embedding soot into the fibers. Change the water often and use a patting motion instead of dragging the cloth. After cleaning, let the mattress dry again.

To prevent future smoke issues, sofa shampooing services consider using a high-quality, breathable mattress protector. It acts as a barrier against odors and spills. Additionally, ensure your fireplace is properly vented and cleaned regularly to reduce the chance of smoke entering your living space. With consistent care and the right cleaning techniques, you can restore your mattress to a fresh, odor-free state.
