Two sofas that look like the same fabric can require different care. The upholstery cleaning code and cushion construction set the method.
Vacuum before adding moisture
Remove loose cushions when possible and vacuum seams, folds, and the deck beneath them. Wetting dust and crumbs can turn them into grime.
Find the cleaning code
On common North American tags, W generally allows water-based products, S calls for solvent, WS allows either, and X limits cleaning to vacuuming or professional methods. Follow the actual manufacturer label on your furniture.
Test any cleaner in a hidden area
Check for dye transfer, texture change, or a ring before treating a visible stain. Put a small amount on the cloth rather than saturating the cushion.
Work from the stain edge inward
Blot instead of scrubbing sideways. Repeat with small amounts and remove cleaner residue as the product directs. Large stains may require treating a slightly wider controlled area to avoid a water line.
Drying is part of cleaning
Ventilate and stand cushions so air reaches multiple sides. Filling that stays damp for many hours can develop odor or mold.
Large stains, delicate upholstery, S/X codes, or valuable furniture are good reasons to use a qualified upholstery cleaner instead of continuing to add products.
