I would strongly advise against using a steam cleaner on a sofa that is labeled "dry clean only." It's a tempting idea for a deep clean, but you are running a very high risk of causing permanent and irreversible damage to your furniture. That label is a critical warning from the manufacturer for a very good reason.
A "dry clean only" tag, often shown as a "Code S" on the care label, specifically means the fabric is intolerant to water. The material might be a natural fiber like silk, rayon, or wool, or a synthetic blend that reacts poorly to moisture and heat. Introducing the hot water vapor from a steam cleaner can trigger a host of problems, including severe water stains and rings, fabric shrinkage that pulls at the seams, and color bleeding that leaves the material looking faded or blotchy. For fabrics with a delicate texture, like velvet, steam can instantly crush the pile, leaving it flat and permanently altered.
The safest and most effective course of action is to heed the manufacturer's warning. Your best option is to contact a professional upholstery cleaning company that specializes in using water-free, solvent-based cleaning methods. These experts have the right equipment and specialized chemicals to safely lift dirt and oils from the fabric without the risks associated with water. While it may seem like an extra expense, the cost of a professional cleaning is a wise investment compared to the potential cost of having to reupholster or completely replace a ruined sofa.
