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

This comprehensive guide is designed for Sydney residents who often find themselves examining 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 letter on that tag conveys essential information regarding the most appropriate cleaning methods for your fabric. Employing an unsuitable technique can turn a minor blemish into a permanent eyesore.

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 signifies that either type of cleaner is permissible, while X indicates vacuuming only — no water or solvent is permitted, 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 vital to exercise particular caution with S and X tags.

How to Find Your Fabric Cleaning Code

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

Most lounges sold in Australia feature a small white care tag displaying a single letter code. Start by lifting a seat cushion to inspect the underside, as this is the most common place for the tag. If it is not located there, examine inside the cushion zipper, on the back panel, or near the frame. If the tag is still missing, it is advisable to assume the fabric has an S or X code (the more cautious approach) until you can ascertain its cleaning requirements.

Understanding 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 suitable. Using water can cause damage, leading to rings, watermarks, and brown spots, even if the original stain seems 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 performed by a professional.

Identifying the Risks Linked to S and X Codes

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

When accidents happen, the natural reaction is to grab a damp cloth. This method typically works for W fabrics, but it can be detrimental to S or X fabrics. Water may spread dyes and residues to the edges of the damp area, creating a dried ring, or interact with the fibres, leading to a brown halo. This issue is particularly common with velvets, linens, viscose blends, and many contemporary designer fabrics, which are classified as S or X more often than the durable materials from two decades ago.

This common mistake underscores the difficulties associated with DIY spot cleaning — the attempted solution often causes more harm than the original spill.

Essential Steps Prior to Cleaning Your Fabric

Quick Summary: Always verify the cleaning code, blot instead of rubbing, and test any cleaning product on a hidden area first.

Step 1 — Find the tag and comprehend 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 hidden 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, cease further attempts. Additional efforts often result in setting the stain further. At this point, it is wise to consult a professional.

Frequently Asked Questions About Fabric Cleaning

What does the S tag on my sofa indicate?

An S tag signifies 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 applied. Using water on S-coded fabric can result in rings, watermarks, or brown spots, even after the original stain appears 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 sofa?

No. An X code strictly indicates 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 employ appropriate low-moisture techniques. Using water on X fabric is one of the primary causes of permanent damage to a high-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 offers 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 sofa 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?
