Upholstery Cleaning Codes

Somewhere on your couch, usually under a cushion or stapled to the bottom of the frame, is a tiny tag with a single letter on it. That letter is the most important cleaning instruction your furniture will ever give you, and almost nobody reads it until after they've left a water ring the size of a dinner plate on the sofa.

Upholstery cleaning codes work like the care labels in your clothes. They tell you what kind of cleaner the fabric can handle, and what will ruin it. There are only four, and once you know them, you'll never have to guess again.

Where to Find the Cleaning Code

Look in these spots:

• Under the seat cushions, on the deck of the couch
• On a tag sewn into a cushion seam or zipper
• On the underside of the couch or chair
• In the paperwork or online product page from the store

The code is usually a single letter or pair of letters, sometimes in a box, sometimes next to the words "cleaning code."

The Four Upholstery Cleaning Codes

W: Water-Based Cleaner

• Use: Suds from 1/4 teaspoon of clear dish soap whisked into a cup of warm water, an upholstery shampoo or a W-safe foam cleaner.
• Avoid: Soaking it. Even W fabric can mildew or leave a ring if you saturate the cushion.
• Steam cleaning: Usually fine, with a light touch and fast drying.

S: Solvent Only

S fabric can't handle water. Water can leave rings, shrink the fabric or make the colors bleed. Clean it with a water-free dry-cleaning solvent instead. Microfiber, rayon, many velvets and some natural fibers are often coded S.

• Use: A water-free upholstery or dry-cleaning solvent, applied to a white cloth first, never straight onto the fabric. Rubbing alcohol works well on most microfiber.
• Avoid: Water, dish soap, steam cleaners and water-based spot removers. Yes, even "just a little water" on a spill.
• Safety: Open a window, and keep solvents away from flames.

W/S: Water or Solvent

he most forgiving fabric. You can use mild suds or a solvent, whichever works best on the stain in front of you. Water-based for juice and coffee, solvent for grease and ink.

• Use: Either dish soap suds or a dry-cleaning solvent. Not both at once.
• Avoid: Overwetting, same as W.

X: Vacuum Only

X means no cleaners at all, wet or dry. You can vacuum and brush it to remove surface dust and dirt, and that's it. Anything more, including spot cleaning, is a job for a professional upholstery cleaner. X is common on delicate natural fabrics and some specialty weaves.

• Use: A vacuum with a soft brush attachment.
• Avoid: Water, solvents, spot removers, fabric fresheners and steam.
• Spills: Blot gently with a dry white cloth and call a pro.

Code Variations You Might See

• S/W, SW or WS: Same as W/S. Water or solvent.
• W-S or W or S: Also the same as W/S.
• Care symbols or written instructions: Some furniture, especially from overseas, uses clothing-style symbols or a sentence like "professional cleaning only" instead of a letter. Follow whatever it says. "Professional only" is the same as X.
• "Removable, machine washable covers": Only trust this if it's written on the tag. A zipper alone doesn't mean the cover is washable. Zippers are usually there for a snug fit.

What If There's No Cleaning Code?

Old couches, vintage finds, hand-me-downs and the chair from your aunt's garage often have no tag at all. Here's how to play it safe:

1. Start with vacuuming. It's safe for everything.
2. Treat the fabric like an S until you know otherwise.
3. Test any cleaner on a hidden spot, like the back, the underside of a cushion or inside a skirt. Let it dry completely, then check for rings, fading or stiffness.
4. If the fabric is silk, velvet, antique or anything you'd cry over, call a professional.

Check the Code Before You Buy

Here's the tip I wish someone had given me before I bought my first white couch: check the cleaning code in the store. With kids, pets or a husband who eats chili in front of the game, look for W or W/S. An S couch can work, but every spill becomes a solvent project. An X couch in a family room is a sofa-shaped professional cleaning bill.

While you're at it, ask about durability. Furniture fabric is rated in "double rubs," the number of times a machine can rub back and forth across it before it shows wear:

• Under 9,000 double rubs: Delicate. Fine for a formal living room chair nobody actually sits in.
• 9,000 to 15,000: Light duty. Good for occasional use.
• 15,000 and up: Heavy duty for a home. This is what you want for the family room couch.
• 30,000 and up: Commercial grade. Built for hotel lobbies, and for teenagers.

Tight weaves, solid colors in mid-tones, and patterns hide wear and stains best. More furniture buying advice is in my furniture shopping ideas.

Upholstery Cleaning Codes: Quick Answers

What do upholstery cleaning codes mean?

W means water-based cleaners are safe. S means solvent only, no water. W/S means you can use either. X means vacuum only, and anything more needs a professional.

What does S mean on a couch tag?

S means clean only with a water-free dry-cleaning solvent. Water can leave rings or stains on S fabric. Apply the solvent to a cloth, not directly to the couch, and test a hidden spot first.

Can I use water on an S couch?

No. Even a little water can leave a ring. For microfiber S couches, rubbing alcohol is the standard fix because it evaporates fast and doesn't leave a mark.

What happens if you use water on an X couch?

You risk water rings, shrinking, color bleeding or a stiff, matted patch. If it's already happened, let it dry without rubbing and call a professional upholstery cleaner.

What's the best upholstery cleaning code for families?

W or W/S. Both can be spot-cleaned with mild soap suds, so spills are easy to handle at home.
