Upholstery Cleaning Codes Explained: W, S, W/S and X

Before you attack a stain on your sofa, find the manufacturer's tag โ€” usually under a seat cushion or on the deck. It has a letter code that tells you how the fabric can safely be cleaned.

W โ€” Water-based cleaners

The fabric can be cleaned with water-based products. This is the easiest code to clean, but over-wetting can still cause browning or shrinkage, so less is more.

S โ€” Solvent only

Use only water-free dry-cleaning solvents. Water can leave rings, spots or shrink the fabric. Many microfiber sofas are S-coded โ€” this is where most DIY disasters happen.

W/S โ€” Either

Water-based or solvent cleaners can be used. Professionals choose based on the type of soil.

X โ€” Vacuum only

No liquid cleaners at all โ€” vacuuming or light brushing only. Call a professional before trying anything else.

Tips for spills

  • Blot, don't rub.
  • Test any product on a hidden area first.
  • Avoid colored cloths that can transfer dye.
  • If the stain doesn't budge, stop โ€” heat and scrubbing can set it permanently.
