The answer to 'upholstery odor' is that common causes include pet accidents, spills, mold, mildew, or lingering odors from food, smoke, or other sources. Symptoms may include a persistent, unpleasant smell that doesn't go away with normal cleaning. Solutions can range from DIY spot cleaning to professional deep cleaning and deodorizing, depending on the severity of the issue.
For mild odors, homeowners can try DIY methods like blotting up spills, using a fabric cleaner, or sprinkling baking soda and letting it sit before vacuuming. For more stubborn odors or widespread issues, it's best to call in a professional upholstery cleaning service to properly identify and treat the source of the problem.
