W, S, W/S, X: read the label before you clean.

Find the instructions for the whole item

Check under a loose seat cushion or beneath the furniture for a care tag. If the tag is missing, look up the model and fabric on the maker’s website or contact the retailer. Keep a photo of the label with your purchase details so you can find it before the next spill.

Read beyond the letter. The cover, lining, cushion filling, and construction can affect the allowed method. If a fabric supplier’s generic advice differs from the furniture maker’s instructions, ask the maker to resolve the difference before cleaning.

What the common codes tell you

W

A water-based upholstery shampoo or foam is the usual permitted spot-cleaning category. Avoid over-wetting. W does not automatically authorize washing a cover or using an extraction machine.

S

A water-free dry-cleaning solvent is the usual category. Do not substitute water. This code is not an invitation to experiment with household solvents; obtain product-specific advice.

W/S

Also written WS or SW. The instructions may allow a water-based upholstery product or a suitable solvent. The stain, product directions, and item’s restrictions still matter.

X

Vacuum or lightly brush as directed. Do not apply water-based, solvent-based, foam, or liquid cleaners.

These summaries draw on Ashley’s cleaning-code definitions and La-Z-Boy’s fabric instructions.

A zipper does not mean machine washable

Being able to remove a cushion cover does not tell you whether it can go into a washing machine. Look for explicit laundering instructions for that exact cover, including the cycle, temperature, detergent, and drying method.

For example, IKEA’s KIVIK Gunnared cover has specific machine-washing instructions and says not to tumble dry. That is a product-specific allowance, not a rule for other removable covers. If washing is not expressly allowed, leave the cover on and seek advice.

Check the method, not just the cleaner

Steam, hot-water extraction, and spot cleaning are different processes. A machine’s upholstery attachment does not prove the furniture can tolerate that machine. La-Z-Boy’s W instructions advise against hot-water extraction and steam cleaning. Other manufacturers may allow a different approach for particular products.

Before any allowed treatment, test a hidden area as directed. Check it again when dry. A successful small test is useful, but it cannot guarantee that every part of an aged or previously treated item will react identically.

Make uncertainty easier to resolve

Send the manufacturer or cleaner a full-item photo, a clear label photo, the model or fabric name, and close-ups of the concern. Explain previous treatments. If there is no readable label, say so rather than choosing the nearest-looking fabric online.
