The provided context does not offer specific instructions on how to remove vomit smell from a sofa. Therefore, this answer is based on general professional cleaning knowledge.
To effectively clean and deodorize a sofa after such an incident, you must act quickly and follow a multi-step process. First, remove any solid residue from the upholstery using a spoon or a dull knife, being careful not to press the material further into the fabric. Once the solids are gone, gently blot the affected area with a clean, dry cloth or paper towels to absorb as much of the liquid as possible. Avoid rubbing, as this can spread the stain and embed the odor-causing particles deeper into the sofa's fibers.
Next, prepare a cleaning solution. A simple and effective option is to mix equal parts of white vinegar and water in a spray bottle. Before applying it to the stain, it is crucial to spot-test the solution on an inconspicuous area of the sofa to ensure it does not cause discoloration. Lightly spray the solution onto the soiled area and blot it with a clean cloth, working from the outside of the stain inward. After cleaning, blot the spot with a cloth dampened with plain water to rinse the area.
To eliminate the persistent smell, deodorizing is the most critical step. Once the spot is damp but not soaking wet, sprinkle a generous layer of baking soda over the entire area. Baking soda is a natural absorbent that will draw out the moisture and neutralize the acidic odors. Allow the baking soda to sit for at least several hours, or preferably overnight. The longer it sits, the more effective it will be. Finally, use a vacuum with a brush attachment to thoroughly remove all the dried baking soda from the sofa. For particularly stubborn odors, you may also consider using a commercial enzymatic cleaner, which is specifically designed to break down the organic proteins that cause the smell. Always follow the product's instructions for the best results.
