Cleaning upholstery at home starts with checking the manufacturer’s cleaning code (W, S, W/S, or X) on the furniture tag, then vacuuming thoroughly and spot-cleaning with the method that code requires.
Most people grab any spray and start scrubbing. That’s how upholstery fabric gets ruined. The real system is simple but exact: find the tag, match the code, blot — don’t rub. This guide walks through the code method, the step order, and the spot treatments that actually work for the stains that show up most often.
What Do The Upholstery Cleaning Codes Mean?
Every piece of furniture has a cleaning code stamped on its tag, usually under the cushion or attached to the frame. The code tells you exactly what liquid or cleaner the fabric can safely handle. Ignoring it is how water rings and shrinkage happen.
| Code | Safe Cleaner | How To Clean |
|:— |:— |:— |
| **W** | Water-based cleaner | Mild dish soap foam or BISSELL Little Green formula, applied and extracted dry |
| **S** | Solvent only (water-free) | Rubbing alcohol or a dry-cleaning solvent — never water |
| **W/S** | Either water or solvent | Pick the method that fits the stain type |
| **X** | Vacuum only | No liquids, foams, or solvents at all — just vacuuming and light brushing |
If the tag is missing, test a hidden area (under a cushion is best) with your chosen method before touching the visible fabric.
How To Spot Clean Upholstery The Right Way
Spot cleaning works if you catch the spill fast and follow the code. The mistake people make is rubbing — that pushes the stain into the padding. Blotting is the only action that removes the stain.
Blot fresh spills immediately with a clean white cloth, working inward from the outer edge. For W or W/S fabric, mix equal parts white vinegar and water or use a dish-soap foam (just the foam, not the liquid). Lightly mist the area or dab with a damp microfiber cloth — never soak. For S-coded fabric, dab with rubbing alcohol on a cotton ball. For any stain, let the solution sit for a minute, then blot dry.
Deep Cleaning Every Two Months
For W and W/S fabric, a deep-clean machine like the BISSELL Little Green pulls out dirt that vacuuming and spot treatment miss. Fill the clean tank to the fill line with warm water, add formula to the formula line, and start at the top edge. Spray enough to dampen the fabric and backing, use the bristle tool to work the solution in gently, then turn off the sprayer and pull the machine back to extract. Let the furniture air dry completely — 4 to 6 hours — with a fan pointed at it. Damp cushions left to sit grow mold.

Targeted Stain Treatments That Work
Different stains need different methods. One approach does not handle grease, coffee, and ink the same way.
- Grease or oil: Sprinkle cornstarch on the spot, let it sit for 15 minutes to absorb the oil, then vacuum the powder away.
- Coffee, tea, or wine: Blot the excess liquid, dab with warm water and a drop of mild dish soap, let it sit for a minute, then blot dry with a clean cloth.
- Blood or food stains (protein): Use cold water only with a little mild soap. Heat sets protein stains permanently.
- Ink: Dab carefully with rubbing alcohol on a cotton ball, then blot. Do not rub — ink spreads fast.
- Odors: Sprinkle baking soda over the surface, leave it for 15–20 minutes, then vacuum thoroughly.
For any stubborn stain on an S or X code, or for large pieces with old damage, call a professional upholstery cleaner. Spot treating antique or heirloom fabric at home carries real risk.
FAQs
Can I use a steam cleaner on upholstery?
Only on fabric with a W or W/S code, and only with the machine set to low moisture. A steam cleaner that soaks the cushions can damage the backing and promote mold — keep the contact brief and follow with air drying.
What happens if I use water on an S-code fabric?
Water causes the backing to shrink, the fabric to wrinkle, and in many cases permanent discoloration. Once water hits S-coded fabric, professional repair may be the only option.
How often should I vacuum my couch?
Weekly for high-use areas like the center cushions and armrests, and every two weeks for the rest. Use the upholstery attachment with long, slow strokes, and the crevice tool to get crumbs and dust out of the seams.
