Beware of Upholstery Cleaning Codes!

by CLC Extreme Clean – Ruidoso, New Mexico
If you’ve ever looked closely at the tag on your sofa or chair, you might have noticed a small letter code that’s easy to overlook. Those upholstery cleaning codes are more important than most homeowners realize. They’re designed to protect your furniture and guide the proper cleaning method. Using the wrong approach could cause shrinking, discoloration, water rings, or even permanent fabric damage.
Where to Find the Code Upholstery cleaning codes are set by the furniture manufacturer and are usually found under seat cushions or along the frame. Each code tells you which cleaning methods are safe for that specific fabric. The most common codes are W, S, WS (or SW), and X.
What the Codes Mean W – Water-Based Cleaning A “W” code means the fabric can be cleaned using water-based solutions such as mild detergents or professional upholstery shampoos. However, that doesn’t mean soaking the fabric is safe!
Too much moisture can seep into the cushions or backing and cause browning, odors, or even mold growth. Controlled application and proper drying are key.
S – Solvent Cleaning Only An “S” code means water could harm the fabric. These materials must be cleaned using solvent-based products. Water can cause shrinking, rings, or texture changes. Many natural fibers and delicate weaves fall into this category—making professional care essential. At CLC Extreme Clean, we have the right solvents and training to clean these fabrics safely.
WS (or SW) – Water or Solvent Cleaning This flexible code means that either water-based or solvent-based methods can be used. However, caution still matters. Always test in an inconspicuous area first, and never scrub aggressively or over wet the fabric.
X – Vacuum Only The most restrictive code of all—“X”—means no water or solvents should ever be used. Light vacuuming or gentle brushing is the only recommended maintenance. Attempting to spot clean X-coded fabrics often results in irreversible damage.
Why Professional Help Matters Reading the tag is just the first step. Fabric age, previous cleanings, wear, and even hidden construction materials can affect how upholstery reacts. That’s why two chairs that look alike may require very different treatments.
