W, S, W-S, and X Tags Explained for Lounges

This detailed guide serves Sydney residents who often find themselves inspecting the small fabric tag tucked beneath their lounge cushions, pondering the importance of the letter displayed before reaching for a cleaning cloth. At Wundaguard, we frequently receive questions regarding this matter, particularly after someone has attempted to clean a stain, only to inadvertently exacerbate the issue.
The single letter on that tag conveys crucial information about the safest cleaning methods for your fabric. Using an inappropriate technique can transform a minor blemish into a lasting eyesore.

Quick Summary: The letter denotes the manufacturer’s cleaning code. A W signifies that water-based cleaners are appropriate, S indicates that only solvent-based cleaners are permitted (no water), W-S indicates that either type of cleaner is acceptable, and X signifies vacuuming only — no water or solvent, with professional cleaning required.
Using plain water on S or X fabrics can result in irreversible watermarks.

Now, let’s explore what each code signifies and why specific attention is necessary for S and X tags.

Locating Your Fabric Cleaning Code

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

Most lounges sold across Australia feature a small white care tag containing a single letter code. Begin by lifting a seat cushion to check the underside, as this is the most common placement for the tag. If the tag is not located there, look inside the cushion zipper, on the back panel, or near the frame. If you still cannot find a tag, it’s safer to assume the fabric has an S or X code (the more cautious stance) until it can be identified.

Interpreting 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 safely clean it with a water-based product, such as 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 suitable. Using water can cause significant damage, resulting in rings, watermarks, and brown spots, even if the stain seems to have been removed.
• W-S (or S-W): Either water-based or solvent-based cleaners are permissible. This option offers the most flexibility, but remember to blot and conduct a test rather than soaking the fabric.
• X (vacuum only): No water or solvent is permitted. These fabrics should only be vacuumed or lightly brushed. Any liquid cleaning needs to be performed by a professional.

Recognising the Hazards of S and X Codes

Quick Summary: Many people instinctively grab water and a cloth, which often results in permanent marks on S or X fabrics.

When spills occur, the natural instinct is to reach for a damp cloth. This method may work for W fabrics, but it can be detrimental for S or X fabrics. Water can transport dyes and old residues to the outer edges of the wet area, leaving a dried ring, or it may react with the fibres, creating a brown halo. This issue is particularly common with velvets, linens, viscose blends, and many contemporary designer fabrics, which are more frequently classified as S or X compared to the durable materials from two decades ago.

This common error highlights why DIY spot cleaning can intensify stains; the attempted solution often causes more harm than the initial spill.

Essential Steps to Take Before Cleaning Your Fabric

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

Step 1 — Locate the tag and understand the code. If it indicates S or X, avoid using water.

Step 2 — Immediately blot the spill with a clean, dry, light-coloured cloth. Press, lift, and repeat. Rubbing is a mistake — it can push the spill deeper into the fabric and flatten the fibres.

Step 3 — If the code permits 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. Further attempts often lead to setting the stain deeper. At this point, it is advisable to consult a professional.

When to Engage a Professional Cleaning Service

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

Since 1983, we have provided this indispensable 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 employ methods compatible with the cleaning code and the fibre type, conduct tests before treatment, and carefully manage moisture to ensure the fabric dries evenly without unsightly rings.

This is why several leading 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 demands meticulous care for showroom presentation, it deserves the same level of attention in your home. You can explore our complete range on our furniture cleaning page, with fabric protection starting from $44 per seat.

Common Queries About Fabric Cleaning Codes

What does the S tag on my couch signify?

An S tag indicates that only solvent-based cleaning is allowed. This fabric should only be treated with a water-free, solvent-based (dry) product, and water must never be applied. Using water on S-coded fabric can result in rings, watermarks, or brown spots, even after the original stain seems to vanish. For anything beyond a gentle, tested spot clean, it is advisable to leave cleaning of S fabrics to professionals.

Is it safe to use water on an X-coded lounge?

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

What distinguishes 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 utilised. W-S offers greater options, but always remember to blot instead of soak and test any product on a hidden area first.

What should I do if my lounge lacks a cleaning tag?

If you cannot find a code on the cushions, seams, or back panel, treat the fabric as though 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 lead to costly damages. If you’re uncertain, send us a photo or call us before applying any cleaning method.

What is the cost of professional upholstery cleaning in Sydney?
