W, S, W-S, and X Tags: Essential Guide for Your Lounge

This comprehensive guide is designed for Sydney residents who often find themselves examining the small fabric care tag hidden beneath their lounge cushions, questioning the meaning of the letter displayed on it before reaching for a cleaning cloth. At Wundaguard, we frequently receive inquiries about this topic, particularly following attempts to remove stains that inadvertently worsen the situation.
The single letter on that tag holds vital information regarding the most appropriate cleaning methods for your fabric. Using the wrong technique can turn a minor stain into a permanent blemish.

Quick Summary: The letter indicates the manufacturer's cleaning code. A W denotes that water-based cleaners can be used, S specifies that only solvent-based cleaners are permitted (no water), W-S means either cleaning method is acceptable, while X indicates that only vacuuming is allowed — no water or solvent, requiring professional cleaning instead.
Using plain water on S or X fabrics can lead to irreversible watermarks.

Let’s delve into the implications of each code and discuss why it is crucial to handle S and X tags with particular care.

How to Find Your Fabric Cleaning Code

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

Most lounges sold in Australia include a small white care tag that displays a single letter code. Start by lifting a seat cushion to inspect the underside, as this is the most common location for the tag. If you do not find it there, examine inside the cushion zipper, on the back panel, or near the frame. If the tag remains elusive, it is wise to assume the fabric has an S or X code (the more cautious approach) until you ascertain its cleaning requirements.

Decoding 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): This code permits safe cleaning with a water-based product, such as a foam cleaner or upholstery shampoo that has been lathered. It is the most forgiving code for careful spot cleaning at home.
• S (solvent only): Only a water-free, solvent-based (dry) cleaner is acceptable. The use of water can cause damage, leading to rings, watermarks, and brown spots, even if the original stain appears to have been removed.
• W-S (or S-W): Both water-based and solvent-based cleaners are permissible. This option provides the most flexibility, but always blot and conduct a test instead of soaking the fabric.
• X (vacuum only): Neither water nor solvent is allowed. These fabrics must only be vacuumed or lightly brushed. Any liquid cleaning should be reserved for a professional.

Understanding the Risks of S and X Codes

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

When spills occur, the natural instinct is to grab a damp cloth. This method usually works for W fabrics, but it can be detrimental to S or X fabrics. Water can spread dyes and old residues to the edges of the wet area, creating a dried ring, or interact with the fibres, leading to a brown halo. This issue is especially common with velvets, linens, viscose blends, and many modern designer fabrics, which are more frequently classified as S or X compared to the durable materials of two decades ago.

This common mistake underscores the difficulties of DIY spot cleaning — the attempted remedy often causes more damage than the initial spill.

Crucial Steps Before Cleaning Your Fabric

Quick Summary: Always check 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, 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 allows for 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 gentle blotting does not lift the stain, stop further attempts. Additional efforts often lead to setting the stain deeper. At this stage, it is best to consult a professional.

When to Seek Professional Cleaning Services

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 avoid permanent damage.

Since 1983, we have offered this essential service. An X-coded lounge cannot be cleaned with water at home, while an S-coded lounge requires the correct solvent and technique, not just any supermarket cleaner. We employ methods that align with the cleaning code and 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 our services for addressing marks after delivery and for ongoing maintenance. They trust us to clean and protect their showroom stock. If delicate fabric deserves careful attention for showroom presentation, it certainly merits the same consideration in your home.

Frequently Asked Questions About Fabric Cleaning

What does the S tag on my couch represent?

An S tag indicates that only solvent-based cleaning is permitted. This fabric should be cleaned exclusively with a water-free, solvent-based (dry) product, and water must never be applied. Using water on S-coded fabric can create rings, watermarks, or brown spots, even when the original stain seems to have been removed. 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 permitted at home. These fabrics are designed to be vacuumed or lightly brushed, with any liquid cleaning reserved for professional services that utilise suitable low-moisture methods. Using water on X fabric is one of the leading causes of permanent damage to a quality lounge.

What sets W apart from 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 either water-based or solvent-based cleaners can be safely utilised. W-S provides greater flexibility, 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 be cautious — 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 damage. If you’re uncertain, send us a photo or call us before attempting any cleaning method.

What is the cost of professional upholstery cleaning in Sydney?
