How to Clean a Fabric Couch (Step-by-Step, By Cleaning Code)

Couches collect a surprising amount of dust, crumbs, pet hair and body oils, even if they look clean. Before you start scrubbing, there's one thing you must check, because the wrong cleaner can leave permanent water rings or damage the fabric.

Step 1: Find the Cleaning Code

Look for a tag under the cushions or under the couch. You'll see one of these letters:

W: Use water-based cleaners. Most common and easiest to clean.
S: Use solvent-based cleaners only (no water). Water can leave stains.
W/S or SW: Either water or solvent cleaners are fine.
X: Vacuum only. Don't use any liquid cleaner. Call a professional for stains.

If there's no tag, test any cleaner on a hidden area first, like the back or underside.

What You'll Need

A vacuum with an upholstery attachment
Baking soda
Clear dish soap and warm water (for W codes)
Rubbing alcohol in a spray bottle (for most S codes)
White microfiber cloths
A soft-bristle brush

Step 2: Vacuum Everything

Remove the cushions and vacuum the cushions, the frame, the arms and all the crevices. Use the crevice tool to reach deep into the seams where crumbs and pet hair hide.

Step 3: Deodorize with Baking Soda

Sprinkle baking soda over the fabric and let it sit for 20–30 minutes (or a few hours for strong smells). Vacuum it up thoroughly. This step is safe for all codes except X.

Step 4: Clean the Fabric

For W or W/S Codes

Mix 1 teaspoon of clear dish soap into 2 cups of warm water.
Dip a cloth, wring it out well, and gently wipe the fabric. Don't soak it.
Blot stains rather than rubbing them.
Go over the area with a cloth dampened with plain water to remove soap.
Blot dry with a clean towel.

For S Codes (Including Many Microfiber Couches)

Lightly spray rubbing alcohol on a small section.
Gently scrub with a white cloth or soft sponge. You'll see dirt lift onto the cloth.
Let it dry (alcohol evaporates quickly), then brush the fabric with a soft-bristle brush to fluff it back up.

For X Codes

Vacuum and use baking soda only. For stains, hire a professional upholstery cleaner.

Step 5: Let It Dry Completely

Open windows or point a fan at the couch. Don't sit on it or put cushions back until everything is fully dry, to avoid water marks and mildew.

Tips for Common Couch Stains

Food and drinks: Blot right away, then use the method for your code.
Greasy spots (from hair or hands): Sprinkle cornstarch, let it sit, brush off, then clean.
Pet accidents: Use an enzyme cleaner made for pet urine on W-code fabric, following the label.

How to Keep Your Couch Fresh

Vacuum it weekly.
Flip and rotate cushions every few weeks so they wear evenly.
Use a washable throw where pets or kids sit most often.

FAQ

Can I wash removable cushion covers in the washing machine? Only if the care tag says so. Many covers shrink or lose their shape. When in doubt, spot-clean.

Why did my couch get water rings after cleaning? Usually because too much water was used, or the fabric was an S code. Clean the whole cushion evenly, not just the spot, to avoid rings.

How often should I deep clean a couch? Every 6–12 months, more often if you have pets or kids.
