Clean a couch at home by vacuuming it, blotting spills, checking the care tag’s cleaning code, and using only the cleaner that code allows.
Cleaning a couch without checking its upholstery code first is how fabric gets ruined. The fix for how to clean a couch at home comes down to a single letter on the manufacturer’s tag — “W,” “S,” “WS,” or “X” — and the right steps around it.
Read the Care Tag First
The letter on the tag tells you exactly what liquid, if any, can touch the fabric. Manufacturers sew these codes into the cushion or under the frame for a reason.
- W: Water-based upholstery cleaner only. A mild soap solution works.
- S: Dry-cleaning solvent only. Water will stain or shrink this fabric.
- WS: Either water-based or solvent-based products are safe.
- X: Vacuum or light brushing only. No liquid cleaner of any kind.
Ashley Furniture’s cleaning-code guide spells out the same system. When the tag is missing or illegible, pretest any cleaner on a hidden spot under the cushion and give it a full 24 hours to dry.
Vacuum Weekly, Blot Spills Immediately
Regular vacuuming does more for a couch than any deep cleaning. Use the upholstery attachment to vacuum the back, arms, skirt, cushions, seams, buttons, and under removable cushions. Weekly is ideal; monthly is the minimum for a lightly used couch.
Blot the spot with a clean cloth, working from the outside toward the center so the stain doesn’t spread. Keep blotting until the cloth picks up nothing more, then let it dry completely.
Deep Clean by Fabric Code
Once the tag says a liquid cleaner is safe, spot-test it on a hidden area first and wait for it to dry. This test catches color bleeding before it ruins a visible cushion.
For water-safe fabrics, a mild solution of 1/4 teaspoon dish soap in 1 cup of warm water handles most stains. Bissell’s upholstery guide confirms that a gentle, soap-based mix applied with a cloth beats harsh chemicals. Dip the cloth, wring it well, and blot the stain — the cloth should be damp, never soaked.
For solvent-only “S” fabrics, use a dry-cleaning solvent product and follow its label exactly. Work in a ventilated room, apply lightly, and blot with a clean cloth. You can find upholstery care specifics from Good Housekeeping’s guide to cleaning any couch, which walks through the same code-based approach.
If the couch smells musty and the code allows moisture, a light steam pass followed by another vacuum can lift odors and refresh fibers. Skip this step entirely on “S” or “X” fabrics — steam is water, and those codes forbid it.
Leather is a different animal. Wipe it with a soft, damp cloth and dry it with a second cloth. Conditioning every 6–12 months keeps the leather supple and prevents cracking. Never apply a water-based upholstery cleaner to leather.
What To Skip Every Time
Rubbing stains, over-wetting the fabric, ignoring the care tag, and using the wrong cleaner for the code are the usual culprits. One more: removing cushion covers when the manufacturer says not to. When the label says the cover is removable and washable, follow its laundering instructions precisely.
Before you buy any cleaner, a quick check of the tag saves a couch. And when the stains are beyond what a cloth can fix, a proper upholstery cleaner or steam extraction might be the call — but only for the fabric codes that permit it.
If you are shopping for a new couch and want one that holds up to daily life, the right fabric makes cleaning easier. Our tested picks for the best at-home couch compare materials, durability, and what each one takes to keep looking fresh.
FAQs
What does the “W” and “S” on my couch tag mean?
“W” means the fabric accepts water-based upholstery cleaners only, so a mild soap solution is safe. “S” means the fabric requires dry-cleaning solvent only, and any water will likely stain or shrink it. A “WS” code allows either type.
How often should I clean my couch?
Vacuum the couch weekly, or at least monthly for light use, to keep dust and grit from grinding into the fibers. Blot spills immediately as they happen. Reserve a deeper cleaning with a liquid product for visible stains or an annual refresh, and only on fabrics whose code permits it.
Can I use baking soda to deodorize a couch?
It works on any upholstery because it involves no liquid. Just be sure to vacuum thoroughly so no white residue remains.
