A Hunker report describes using baking soda to help reduce odors on some fabric couches, while stressing that it may not remove smells from deep-set spills or pet urine. Check the couch’s care label and test a hidden area before applying a light layer, then vacuum it up thoroughly.

A Hunker report outlines a low-cost way to help freshen some fabric couches: sprinkle on a light layer of baking soda, leave it for at least 20 to 30 minutes, then vacuum it away. The method is not suitable for every upholstery type, and the report cautions that baking soda may not remove odors that have soaked into fabric, such as pet urine.

Before treating a couch, check its care label, which may be beneath a cushion or on the furniture’s underside. Hunker says labels use codes to indicate appropriate cleaning methods: a “W” generally permits water-based cleaning, while an “X” usually means the fabric should only be vacuumed or brushed. The report recommends testing baking soda on a hidden area first to check for discoloration, and says the test should last as long as the planned treatment.

For a couch that passes the test, remove throws, pillows and cushions, and take small objects out of the seams. Vacuum the upholstery, including crevices, and make sure the fabric is dry. Sprinkle baking soda evenly without rubbing it in aggressively. After leaving it undisturbed for at least 20 to 30 minutes—or longer for stronger odors—vacuum it up. Check seams and cushion sides for residue and vacuum again if needed.

The report advises against using this method on leather, imitation leather, silk and delicate vintage furniture, where baking soda could dry, damage or discolor the material. It can also be difficult to remove from deep-pile upholstery and seams. Baking soda may address odor, but it does not clean away the spill or stain that caused it; visible spills need a suitable fabric cleaner, and some persistent smells may require professional treatment.

When Couch Odors Need More Than Baking Soda

The distinction between freshening fabric and removing the source of an odor matters for homeowners trying to choose a safe, effective response. A light application may help with less serious smells, according to the report, but it should not be treated as a substitute for cleaning a spill or addressing contamination within upholstery.

Checking the label and testing an inconspicuous spot can reduce the risk of fabric damage or discoloration. The extra steps also help readers avoid using a dry powder on materials the report identifies as unsuitable. For deep-set smells, professional cleaning may be more appropriate than repeating a household treatment.

Care Labels Guide Upholstery Cleaning

The Hunker report presents baking soda as one of several household approaches to upholstery odors, not as a universal couch cleaner. Its instructions center on the furniture’s care code, because fabrics vary in which cleaning methods they can tolerate. In the report’s description, a “W” indicates water-based cleaning is generally allowed, while “X” calls for vacuuming or brushing only.

The process also depends on the couch being dry before application and on removing powder fully afterward. Hunker says a longer treatment is possible for stronger smells, but recommends matching the patch test to that duration—for example, an overnight test before leaving baking soda on the full couch overnight.

Limits of the Odor Treatment

The supplied report does not provide comparative testing or a measured success rate for the method, so its effectiveness for a particular couch or odor is not quantified. Results may depend on the upholstery and what caused the smell. Hunker says odors that have soaked into fabric, including pet urine, may require professional cleaning, but the material does not specify which service or treatment will work in every case.

The report also does not identify the care codes for every couch or fabric blend. Readers should rely on their own furniture’s label and manufacturer guidance rather than assume the same treatment applies across upholstery types.

Check the Label Before Treating

For readers considering the method, the next step is to locate the couch’s care label and follow its instructions. If the material appears suitable, test a hidden patch for the full intended treatment time, then proceed only if there is no visible change. Keep children and pets away from the treated furniture while baking soda is on it.

After vacuuming, inspect seams and cushions for leftover powder. If a visible spill remains, use a cleaner appropriate for the fabric; if an odor persists or seems deep-set, the report suggests that professional cleaning may be needed. The supplied material gives no further schedule or announcement beyond these care steps.

Key Questions

What is baking soda meant to do on a couch?

According to Hunker, baking soda may help reduce or neutralize some odors on suitable fabric upholstery. It does not remove the spill or stain that may be causing the smell.

How long should baking soda stay on a fabric couch?

The report recommends leaving a light, even layer undisturbed for at least 20 to 30 minutes. It may be left longer for stronger odors, but the hidden-area patch test should match that same duration.

Can baking soda be used on leather or silk upholstery?

Hunker advises against using it on leather, imitation leather, silk or delicate vintage furniture because it could dry, damage or discolor those materials. Check the care label and manufacturer guidance.

Will baking soda remove pet urine odor?

Not necessarily. The report says odors that have soaked into fabric, such as pet urine, may need professional cleaning. Baking soda also will not remove the underlying stain or spill.
