To get the smell of sick out of a sofa, first clean the affected area by blotting it with warm water mixed with a little dish soap, removing as much residue as possible without soaking the fabric. Once clean, cover the spot generously with baking soda and leave it for several hours—ideally overnight—so it can absorb the deep odor before vacuuming it thoroughly. After that, lightly spray a mixture of one part white vinegar and two parts water to neutralize any remaining smell, allowing the sofa to air-dry fully. If the odor still lingers, use an enzyme cleaner (usually sold as a pet stain remover), as this breaks down the proteins in vomit that cause long-lasting odors, giving you the most reliable and complete odor removal.
