W, S, W-S, and X Tags: Essential Guide for Lounges

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

Quick Overview: The letter denotes 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, while X indicates that only vacuuming is permitted — no water or solvent is allowed, necessitating professional cleaning instead.
Applying plain water to S or X fabrics can lead to irreversible watermarks.

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

How to Find Your Fabric Cleaning Code

Quick Overview: Look 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 displaying a single letter code. Start by lifting a seat cushion to check the underside, as this is the most common location for the tag. If it is not there, inspect inside the cushion zipper, on the back panel, or near the frame. If the tag remains elusive, it is wise to treat the fabric as if it has an S or X code (the more cautious approach) until you can ascertain its cleaning requirements.

Decoding Each Fabric Cleaning Code

Quick Overview: W = water-based, S = solvent only, W-S = either type of cleaner, and X = vacuum only.

• W (water-based): This code permits 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 suitable. Using 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 offers the most flexibility, but always blot and conduct a test rather than soaking the fabric.
• X (vacuum only): No water or solvent is allowed. These fabrics must solely be vacuumed or lightly brushed. Any liquid cleaning should be performed by a professional.

Understanding the Risks of S and X Codes

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

When spills occur, the natural reaction is to grab a damp cloth. This method generally 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, resulting in a brown halo. This issue is particularly common with velvets, linens, viscose blends, and many modern designer fabrics, which are classified as S or X more frequently than durable materials from two decades ago.

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

Crucial Steps to Take Before Cleaning Your Fabric

Quick Overview: 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 promptly 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 a hidden area (such as the back corner or under a cushion) and wait for it to dry before treating visible areas.

Step 4 — If gentle blotting does not remove the stain, stop further attempts. Additional efforts often result in setting the stain further. At this point, it is advisable to consult a professional.

When to Seek Professional Cleaning Services

Quick Overview: 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.

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 create rings, watermarks, or brown spots, even after the original stain seems to have disappeared. 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?

Costs vary based on fabric type, lounge size, and its condition. The best approach is to request a quick quote instead of 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.
