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

This comprehensive guide is designed for Sydney residents who often find themselves inspecting the small fabric tag hidden beneath their lounge cushions, contemplating the meaning of the letter displayed before reaching for a cleaning cloth. At Wundaguard, we frequently receive inquiries about this subject, especially after someone has attempted to clean a stain and unintentionally worsened the situation.
The single letter on that tag conveys vital information about the safest cleaning methods for your fabric. Selecting an inappropriate technique can turn a minor blemish into a permanent eyesore.

Quick Overview: 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 specifies vacuuming only — no water or solvent, necessitating professional cleaning.
Using plain water on S or X fabrics can lead to irreversible watermarks.

Let’s delve deeper into the meaning of each code and understand the importance of special care required for S and X tags.

How to Find Your Fabric Cleaning Code

Quick Overview: Look beneath a seat cushion, on the back of the lounge, or on the tag sewn into a seam near the base.

Most lounges sold in Australia come with a small white care tag that displays a single letter code. Start by lifting a seat cushion to check underneath, as this is the most common location for the tag. If you don’t find it there, inspect the inside of the cushion zipper, the back panel, or near the frame. If the tag remains elusive, assume the fabric has an S or X code (the more cautious approach) until it can be identified.

Understanding Each Fabric Cleaning Code

Quick Overview: W = water-based, S = solvent only, W-S = either cleaner type, 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 damage, leading to 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 permitted. These fabrics should only be vacuumed or lightly brushed. Any liquid cleaning should be performed by a professional.

Understanding the Risks Associated with S and X Codes

Quick Overview: Many instinctively reach for 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 grab a damp cloth. This method usually works well for W fabrics, but it can be damaging for S or X fabrics. Water 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, creating a brown halo. This issue is common with velvets, linens, viscose blends, and many modern designer fabrics, which are more frequently classified as S or X compared to the durable fabrics from two decades ago.

This common mistake illustrates why DIY spot cleaning can worsen stains — the attempted remedy often causes more harm than the original spill.

Crucial Steps to Take Before Cleaning Your Fabric

Quick Overview: Always check the cleaning code, blot rather than rub, and test any cleaning product on a hidden area first.

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

Step 2 — Blot the spill immediately 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 (such as the back corner or beneath 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 more firmly. At this point, it is advisable to consult a professional.

When to Contact a Professional Cleaning Service

Quick Overview: Any S or X fabric, any stubborn stain, and delicate materials like velvet or linen should be entrusted to a professional to avoid 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 utilise methods that comply with the cleaning code and the fibre type, conduct tests prior to 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 handling 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 certainly 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 About Fabric Cleaning

What does the S tag on my couch mean?

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

Is it safe to 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 intended 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) signifies that either water-based or solvent-based cleaners can be safely employed. W-S offers more 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 lacks a cleaning tag?

If you cannot find a code on the cushions, seams, or back panel, treat the fabric as though 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 can be 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?

Costs vary depending on the fabric type, the size of the lounge, and its condition. The best approach is to request a quick quote rather than making assumptions. Our fabric protection services start from $44 per seat, and we will provide a clear cleaning price after assessing your lounge’s specific needs.
