Understanding W, S, W-S, and X Tags on Your Lounge

This guide is for anyone in Sydney who finds themselves examining the small fabric tag hidden beneath their lounge cushion, pondering the meaning of the letter it displays before they reach for a cloth to start cleaning. At Wundaguard, we frequently receive inquiries about this, particularly after someone has attempted to tackle a stain and inadvertently made it worse.
That single letter provides crucial information on the safe cleaning methods for your fabric, and using the wrong approach can transform a minor mark into a permanent blemish.

Quick Summary: The letter signifies the manufacturer’s cleaning code. A W indicates that water-based cleaners are acceptable, S means only solvent-based cleaners should be used (no water), W-S permits either type of cleaner, and X specifies vacuuming only — no water, no solvent, and professional cleaning is necessary.
Using plain water on S or X fabrics can result in watermarks that become irreparable.

Let’s explore what each code signifies and why the S and X tags require particular attention.

Locating the Fabric Cleaning Code

Quick Summary: Look under a seat cushion, at 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 displaying a single letter code. Start by lifting a seat cushion to check the underside, as this is the most common location. If the tag isn’t there, examine the inside of the cushion zip, the back panel, or the area near the frame. If you still can’t locate a tag, treat the fabric as if it has an S or X code (the safer option) until you clarify its identity.

Understanding Each 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 using a water-based product, such as a foam or upholstery shampoo that's been lathered up. This is the most forgiving code for careful spot cleaning at home.
• S (solvent only): Only use a water-free, solvent-based (dry) cleaner. Water can cause damage here, leading to rings, watermarks, and brown spots on these fabrics, even if the stain itself appears to be removed.
• W-S (or S-W): You can use either a water-based or a solvent-based cleaner. This gives you the most flexibility, but you should still blot and conduct a test rather than soaking the fabric.
• X (vacuum only): No water and no solvent allowed. These fabrics should only be vacuumed or lightly brushed at home. Any liquid cleaning should be carried out by a professional.

The Challenges of S and X Codes

Quick Summary: Many instinctively reach for water and a cloth, which is precisely what creates permanent marks on S or X fabrics.

When spills occur, the immediate response is often to grab a damp cloth. With W fabrics, this approach typically works without issue. for S or X fabrics, the water itself is problematic — it can carry dyes and old residues to the edges of the wet area, resulting in a dried ring, or it can react with the fibres and create a brown halo. We observe this frequently with velvets, linens, viscose blends, and many contemporary designer fabrics, which are considerably more likely to be classified as S or X compared to the durable fabrics prevalent twenty years ago.

This common mistake highlights the issue we discussed regarding why DIY spot cleaning can exacerbate stains — the attempted fix often inflicts more damage than the original spill.

Essential Steps Before Cleaning

Quick Summary: Read the cleaning code, blot instead of rubbing, and test any product on an inconspicuous area first.

Step 1 — Locate the tag and understand the code. If it’s labelled 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 the use of a cleaner, test it first on a hidden area (such as the back corner or underneath a cushion) and wait for it to dry before treating visible sections.

Step 4 — If the stain does not lift with gentle blotting, stop. Subsequent attempts usually lead to further setting of the stain. At this point, it’s best to consult a professional.

When to Seek Professional Cleaning Assistance

Quick Summary: Any S or X fabric, any entrenched stain, and delicate materials like velvet or linen should be handed over to a professional to avoid risking permanent damage.

Since 1983, we have provided this crucial service. An X-coded lounge cannot be wet-cleaned at home, and an S-coded lounge requires the correct solvent and technique, not just a supermarket cleaner. We employ methods that align with the cleaning code and the type of fibre, perform tests before treatment, and carefully control moisture to ensure the fabric dries evenly without unsightly rings.

That is why several leading furniture retailers — including Freedom, Lounges Plus, and Strictly Comfort — recommend us for addressing marks post-delivery and ongoing maintenance. They trust us with the cleaning and protection of their showroom stock. If a delicate fabric deserves meticulous care for showroom display, it certainly merits the same attention in your home. You can explore our full range on our furniture cleaning page, with fabric protection starting from $44 per seat.

Common Queries Answered

What does the S tag on my couch indicate?

An S tag signifies solvent only. This fabric should only be cleaned with a water-free, solvent-based (dry) product, and water should never be used. Applying water to S-coded fabric can result in rings, watermarks, or brown spots, even after the original stain appears to be removed. For anything beyond a light, tested spot clean, it’s best to leave S fabric cleaning to the professionals.

Can I apply water to an X-coded lounge?

No. An X code strictly means vacuum only — no water and no solvent are permitted at home. These fabrics are meant to be vacuumed or lightly brushed, with any liquid cleaning reserved for professional services utilising appropriate low-moisture methods. Using water on an X fabric is one of the most frequent causes of permanent damage to a good lounge.

What distinguishes W and W-S cleaning codes?

W means that only water-based cleaners are suitable. W-S (which may also be written as S-W) indicates that either water-based or solvent-based cleaners can be safely used. W-S provides more options, but always remember to blot rather than soak and test any product on a concealed area first.

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

If you cannot locate a code on the cushions, seams, or back panel, treat the fabric as if it has an S or X code to err on the side of caution — vacuum and dry-blot only, avoiding water. Many designer and imported fabrics are sensitive to water, so misjudging the cleaning method can be costly. 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?

The cost varies based on the fabric, the size of the lounge, and its condition. the best course of action is to request a quick quote rather than relying on assumptions.
