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

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

Quick Summary: The letter represents the manufacturer's cleaning code. A W suggests that water-based cleaners are suitable, an S indicates that only solvent-based cleaners are permitted (no water), W-S signifies that either type of cleaner can be used, while X denotes vacuuming only — no water or solvent is acceptable, necessitating professional cleaning instead.
Applying plain water to S or X fabrics can result in irreversible watermarks.

Let’s delve into what each code means and why it is crucial to treat 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 the tag stitched 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 examine the underside, as this is the most common location for the tag. If it is not found there, inspect inside the cushion zipper, on the back panel, or near the frame. If the tag remains hidden, it is wise to assume the fabric has an S or X code (a more cautious approach) until you 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 allows 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. 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 provides 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 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 mishaps occur, the natural response is to grab a damp cloth. This method usually works well for W fabrics, but it can be detrimental to S or X fabrics. Water can spread dyes and 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 contemporary designer fabrics, which are more frequently classified as S or X compared to the durable materials used two decades ago.

This frequent error underscores the difficulties of DIY spot cleaning — the attempted fix 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 — Locate 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 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 lift the stain, cease further attempts. Additional efforts often worsen the situation. At this stage, it is advisable to seek professional assistance.

Frequently Asked Questions About Fabric Cleaning

What does the S tag on my sofa signify?

An S tag indicates that only solvent-based cleaning is allowed. This fabric should exclusively be cleaned with a water-free, solvent-based (dry) product, and water must never be used. Applying water to S-coded fabric can result in rings, watermarks, or brown spots, even after the original stain seems to have disappeared. For anything beyond a light, tested spot clean, it is best 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 intended to be vacuumed or lightly brushed, with any liquid cleaning reserved for professional services that employ appropriate low-moisture methods. Using water on X fabric is a primary cause 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.
