W, S, W-S, and X Tags Explained for Your Lounge

This comprehensive guide is designed for Sydney residents who find themselves inspecting the small fabric tag hidden beneath their lounge cushions, questioning the significance of the letter displayed on it before reaching for a cleaning cloth. At Wundaguard, we often receive inquiries about this topic, especially after someone has attempted to clean a stain and inadvertently worsened the situation.
The single letter on that tag holds essential information regarding the safest cleaning methods for your fabric. Using the wrong technique can turn a minor mark into a permanent eyesore.

Quick Summary: The letter represents the manufacturer's cleaning code. A W indicates that water-based cleaners are suitable, S signifies that only solvent-based cleaners should be used (no water), W-S means either type of cleaner is acceptable, and X designates vacuuming only — no water or solvent, with professional cleaning required.
Applying plain water on S or X fabrics can lead to irreversible watermarks.

Let’s delve into what each code means and why special attention is required for S and X tags.

How to Find Your Fabric Cleaning Code

Quick Summary: Check under a seat cushion, on the back of the lounge, or on the tag stitched into a seam near the base.

Most lounges sold in Australia come with a small white care tag featuring a single letter code. Start by lifting a seat cushion to examine the underside, as this is the most common location for the tag. If it’s not there, look inside the cushion zipper, on the back panel, or near the frame. If you still cannot find a tag, assume the fabric has an S or X code (the more cautious approach) until you can identify it.

Deciphering Each Fabric Cleaning Code

Quick Summary: W = water-based, S = solvent only, W-S = either type of cleaner, and X = vacuum only.

• W (water-based): You can clean it safely with a water-based product, like a foam cleaner or upholstery shampoo that has been lathered. This code is the most forgiving for careful spot cleaning at home.
• S (solvent only): Only a water-free, solvent-based (dry) cleaner is appropriate. Using water can cause damage, resulting in rings, watermarks, and brown spots, even if the stain appears to be removed.
• W-S (or S-W): Either water-based or solvent-based cleaners can be used. This option provides the most flexibility, but always blot and conduct a test instead of soaking the fabric.
• X (vacuum only): No water or solvent is allowed. These fabrics should only be vacuumed or lightly brushed. Any liquid cleaning needs to be performed by a professional.

Understanding the Risks of S and X Codes

Quick Summary: Many instinctively grab water and a cloth, which is exactly what leads to permanent marks on S or X fabrics.

When spills happen, the natural reaction is to reach for a damp cloth. This method usually works for W fabrics, but it can be detrimental for S or X fabrics. Water can transport dyes and old residues to the edges of the wet area, leaving a dried ring, or it can react with the fibers, resulting in a brown halo. This issue is common with velvets, linens, viscose blends, and many modern designer fabrics, which tend to be classified as S or X more than the durable fabrics from two decades ago.

This frequent misstep underscores the issue of why DIY spot cleaning can worsen stains — the attempted remedy often causes more damage than the initial spill.

Critical Steps Before Cleaning Your Fabric

Quick Summary: Always read the cleaning code, blot instead of rubbing, and test any cleaning product on a hidden area first.

Step 1 — Find the tag and understand the code. If it indicates S or X, do not use water.

Step 2 — Blot the spill immediately with a clean, dry, light-colored cloth. Press, lift, and repeat. Rubbing is a mistake — it can push the spill deeper into the fabric and flatten the fibers.

Step 3 — If the code allows for a cleaner, test it first on an inconspicuous area (like the back corner or underneath a cushion) and wait for it to dry before treating visible areas.

Step 4 — If gentle blotting does not lift the stain, stop. Additional attempts often lead to further setting of the stain. At this stage, it is wise to consult a professional.

When to Hire a Professional Cleaning Service

Quick Summary: Any S or X fabric, any stubborn stain, and delicate materials like velvet or linen should be entrusted to a professional to prevent permanent damage.

Since 1983, we have offered this essential service. An X-coded lounge cannot be cleaned with water at home, and an S-coded lounge requires the correct solvent and technique, not just any supermarket cleaner. We utilize methods that are compatible with the cleaning code and the fiber type, perform tests before treatment, and carefully control moisture to ensure the fabric dries evenly without unsightly rings.

This is why several top furniture retailers — including Freedom, Lounges Plus, and Strictly Comfort — recommend us for addressing marks after delivery and for ongoing maintenance. They trust us to clean and protect their showroom stock. If delicate fabric deserves meticulous care for showroom presentation, it definitely warrants the same attention in your home. You can explore our complete range on our furniture cleaning page, with fabric protection starting from $44 per seat.

Frequently Asked Questions

What does the S tag on my couch mean?

An S tag indicates that only solvent-based cleaning is permitted. This fabric should only be cleaned with a water-free, solvent-based (dry) product, and water must never be used. Applying water to S-coded fabric can create rings, watermarks, or brown spots, even after the original stain seems to disappear. For anything beyond a light, tested spot clean, it is advisable to leave S fabric cleaning to the professionals.

Can I use water on an X-coded lounge?

No. An X code strictly means vacuum only — neither water nor solvent is allowed at home. These fabrics are designed to be vacuumed or lightly brushed, with any liquid cleaning reserved for professional services using suitable low-moisture methods. Using water on an X fabric is one of the leading causes of permanent damage to a quality lounge.

What is the difference between W and W-S cleaning codes?

W indicates that only water-based cleaners are suitable for use. W-S (which may also be referred to as S-W) means that either water-based or solvent-based cleaners can be safely utilized. W-S provides increased options, but always remember to blot instead of soak and test any product on a concealed area first.

What should I do if my lounge does not have a cleaning tag?

If you cannot find a code on the cushions, seams, or back panel, treat the fabric as if it possesses an S or X code to err on the side of caution — vacuum and dry-blot only, avoiding water. Many designer and imported fabrics can be sensitive to water, so misjudging the cleaning method can be costly. If you’re unsure, send us a photo or call us before applying any cleaning method.
