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

This comprehensive guide is tailored for residents of Sydney who often find themselves scrutinising the small fabric care tag discreetly positioned beneath their lounge cushions, contemplating the meaning of the letter displayed on it before reaching for a cleaning cloth. At Wundaguard, we regularly receive inquiries on this topic, especially after someone has attempted to remove a stain and inadvertently worsened the situation.
The single letter on that tag holds vital information regarding the most appropriate cleaning methods for your fabric. Using an incorrect technique can turn a minor blemish into a permanent flaw.

Quick Summary: The letter signifies 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 signifies that either type of cleaner is acceptable, while X indicates that only vacuuming is permissible — no water or solvent is allowed, necessitating professional cleaning instead.
Applying plain water to S or X fabrics can result in irreversible watermarks.

Let’s delve into what each code signifies and why it is crucial to handle S and X tags with particular care.

Finding Your Fabric Cleaning Code Made Easy

Quick Summary: Check beneath 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 its underside, as this is the most common location for the tag. If it’s not found there, inspect inside the cushion zipper, on the back panel, or near the frame. If the tag is still missing, it is wise to assume the fabric has an S or X code (the more cautious approach) until you can 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 appropriate. Using water can cause damage, resulting in 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 acceptable. This option offers 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 must only be vacuumed or lightly brushed. Any liquid cleaning should be managed by a professional.

Understanding the Risks of S and X Codes

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

When accidents happen, the natural instinct is to grab a damp cloth. This method may work for W fabrics, but it can be detrimental to S or X fabrics. Water can disperse dyes and old residues to the edges of the wet area, creating a dried ring, or interact with the fibres, resulting in a brown halo. This issue is particularly common with velvets, linens, viscose blends, and many modern designer fabrics, which are frequently classified as S or X, unlike the more durable materials from two decades ago.

This prevalent mistake underscores the challenges of DIY spot cleaning — the attempted solution often causes more damage than the original spill.

Crucial Steps to Take 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, do not use 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 concealed 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 fails to remove the stain, stop further attempts. Additional efforts often result in setting the stain further. At this stage, it is advisable to consult a professional.

Frequently Asked Questions About Fabric Cleaning

What does the S tag on my couch signify?

An S tag indicates that only solvent-based cleaning is permitted. This fabric should solely be cleaned with a water-free, solvent-based (dry) product, and water must never be used. Applying water to S-coded fabric can cause rings, watermarks, or brown spots, even after the original stain appears to have vanished. 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 appropriate low-moisture methods. Using water on X fabric is one of the primary causes of permanent damage to a quality lounge.

What distinguishes W 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 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 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?
