Upholstery Cleaning Codes and Fabric Risk Guide
Decode W, S, WS, SW and X fabric tags, then use the decision tool to identify the safest next step before a spot, odor or cleaning attempt becomes permanent damage.
What W, S, WS and X mean
Look under a seat cushion, beneath the platform, or on the manufacturer’s care sheet. SW is normally read the same way as WS. Record the exact wording because extra instructions can narrow what the letter allows.
Water-based spot cleaning
Use only the water-based shampoo or foam category allowed by the maker. Do not over-wet. Solvent spot cleaners are outside this code.
Water-free solvent
Use only a water-free cleaning-solvent category allowed by the maker. Do not use water. Ventilation and professional handling matter.
Water or mild solvent
The maker allows a water-based upholstery shampoo or foam, or a mild cleaning solvent for spot work. Pretest and avoid saturation.
Vacuum or light brush only
No water-based or solvent-based cleaner should be applied. Routine care is limited to vacuuming or light brushing as directed.
Build a safer next-step plan
Choose the closest verified answer. The result is a conservative planning lane, not a stain-removal guarantee or a substitute for the furniture manufacturer’s instructions.
When the tag is missing or the history is uncertain, choose the cautious answer. Do not combine products while trying to identify the remaining mark.
Quick cleaning-code comparison
| Code | Permitted category | Do not assume | Best next step for overall soil |
|---|---|---|---|
| W | Water-based | Not permission to soak, launder covers, use bleach or automatically use hot-water extraction | Have the full furniture and fabric construction assessed before overall cleaning |
| S | Water-free solvent | Water, steam and water-based foam are not authorized | Use a professional familiar with solvent-cleaning limitations and ventilation |
| WS / SW | Water or mild solvent | The code does not make every product, method or stain-removal chemistry compatible | Match the process to the complete care sheet, soil and construction |
| X | No liquid cleaner | Professional service does not override the no-water, no-solvent boundary | Vacuum or light brush only unless the manufacturer issues different instructions |
| Missing | Unverified | Fiber appearance alone cannot prove compatible chemistry or construction | Identify the maker and fabric, or arrange inspection and testing before treatment |
Why the same letter can still require different plans
The tag usually describes the face fabric
A finished furniture piece can also contain backing, cushion fill, batting, decking, welt cord, trims, adhesives, wood, metal and different fabrics on hidden panels. A compatible spot cleaner for the face fabric does not automatically settle the risks for the entire assembly.
Spot-cleaning instructions are not laundering instructions
A zipper provides access for manufacturing and cushion service. It does not prove that a cover may be removed, washed or dried separately. Removing and laundering a cover can change fit, backing, color or texture even when the visible code includes W.
Six conditions that change the risk
Color movement
Dye transfer onto a white towel, spreading color or a new light area means stop. More moisture or chemistry can enlarge the change.
Rings and browning
A ring, tide line or brown area after drying may involve residue, uneven wetting, soil movement or a material reaction. Identify it before adding product.
Pile and texture
Velvet, chenille and other pile or specialty constructions can show pressure, shading, distortion or texture change that soil removal alone will not correct.
Unknown prior products
Household sprays, protectors, soaps and disinfectants can leave residues or react with the next process. Record the product before treatment.
Pet contamination
Odor can extend beyond the visible face fabric into cushion fill or hidden construction. The care code does not show how deep the contamination traveled.
Damage or wear
Sun fading, abrasion, cracking coatings, weak seams and worn fibers are material conditions. Cleaning cannot rebuild missing color or strength.
Printable pre-cleaning record
Photograph the whole piece and the exact tag before any product is applied. This record helps a retailer, manufacturer or cleaner evaluate what happened later.

Sources and methodology
This guide converts industry guidance into a conservative consumer decision path. The Association for Contract Textiles publishes the W, S, WS and X definitions and repeatedly emphasizes pretesting, moisture control and manufacturer-specific recommendations. Its reference also explains that the cleaning codes are useful but do not provide enough information by themselves for every upholstery decision.

Method note: This tool does not identify fibers, establish dye stability, approve a chemical, interpret a warranty or guarantee removal. The furniture maker’s current care instructions and an on-site inspection take priority.
