Yes, if the care tag says W or WS and the process uses controlled moisture or a gentle garment steamer; no for S or X codes, where solvents or dry methods are required instead. The kicker is that what many people call steam cleaning is often hot-water extraction, a method the professional standard-setter IICRC notes is frequently mislabeled as “steam cleaning,” which is why confusion and damage happens.
A new American National Standard, ANSI/IICRC S300 for Professional Upholstery Cleaning, was published on September 9, 2025, formalizing best practices for fiber ID, methods, and limitations in upholstery care at a moment when DIY “steam” gadgets are surging in homes worldwide. Meanwhile, the global steam cleaner market is projected to grow from USD 3.67 billion in 2024 to USD 6.02 billion by 2032, underscoring a steady shift toward chemical-free, heat-assisted cleaning in living rooms—not just on floors and tiles but on sofas and sectionals too.
Here’s the thing: not every “steam” pass is safe for microfiber, and the wrong move can cause water rings, texture changes, and dye issues, especially on S-coded fabrics where manufacturers call for solvent-only cleaning. This primarily affects consumers trying to deep-clean pet hair and spills, retailers managing returns, and pro cleaners fielding more corrective calls when DIY attempts go sideways right before a holiday gathering, sources say.
The Data
-
The global steam cleaners market was valued at USD 3.45 billion in 2023 and is projected to rise from USD 3.67 billion in 2024 to USD 6.02 billion by 2032, at a 6.4% CAGR as households seek eco-friendlier cleaning methods that sanitize without harsh chemicals.
-
The U.S. furniture market is estimated at USD 172.33 billion in 2024 with multi-year growth ahead, which implies a larger installed base of upholstered seating that needs periodic, careful cleaning to retain value and extend life.
-
A new ANSI/IICRC S300 upholstery-cleaning standard was formally published in September 2025, consolidating best practices on fibers, methods, tools, and limitations—critical context as consumers conflate garment steamers, steam mops, and hot-water extractors.
Why It Matters
Market growth in steam appliances meets a massive and growing furniture base, so the “can I steam it?” question hits millions of microfiber couches—and a misstep can mean permanent water marks or needless service calls if the care code isn’t followed. The latest S300 standard also stresses method selection and limitations, noting that hot-water extraction is often mislabeled as “steam cleaning,” which raises the stakes for precise terminology and technique on microfiber upholstery.
Can You Steam Clean a Microfiber Couch? Step-By-Step
Note: Always verify the care code (W, S, WS, X) before any wet method and test in an inconspicuous spot; when in doubt, lean gentler, not wetter.
Guide 1: Read the Tag, Prep, and Test First
-
Start by finding the care tag under cushions or along seams; W means water-based cleaners are okay, WS means water or solvent, S means solvent-only, and X means vacuum/dry brush only with no liquids.
-
If the tag is missing, many retailers and pros advise assuming solvent-only and spot-testing cautiously in a hidden area before proceeding with any cleaner or heat tool to prevent color loss or water rings.
-
Vacuum the entire couch—including crevices and under cushions—to remove grit and hair that can smear when damp, then set up fans to ensure fast drying after any wet step to minimize watermark risk.
-
Test the least aggressive approach first: a gentle pass with a garment steamer on W/WS fabrics or a light solvent spot treatment on S fabrics, observing for any texture or color change before scaling up.
Guide 2: For W/WS Fabrics Gentle Steam and Low-Moisture Cleaning
-
On W or WS microfiber, a handheld garment steamer can be used gently to lift light soils and reduce allergens; keep the head slightly off the fabric so only vapor touches the pile rather than dripping condensation.
-
Work in small sections with slow, even passes to avoid overwetting, then immediately follow with vacuuming or a microfiber towel to pick up loosened debris and accelerate dry time to prevent rings.
-
If needed, apply a mild, water-based upholstery cleaner after steaming, but continue to keep moisture low; extract or blot thoroughly and maintain airflow until completely dry before sitting back down.
-
Remember that “steam cleaning” in pro contexts often refers to hot-water extraction, which isn’t live steam and uses pressurized water and vacuum; the IICRC notes this distinction because over-wetting and wicking are common pitfalls on upholstery.
Guide 3: For S-Coded Microfiber Solvent-Only Spot Cleaning
-
If the tag shows S, skip water altogether and use a solvent-based upholstery cleaner or isopropyl alcohol for spot cleaning to avoid water rings and fiber distortion that can occur with moisture on solvent-only microfiber.
-
Apply the solvent to a clean cloth rather than directly to the fabric, then dab the stain from the outside in, swapping to fresh sections of the cloth to avoid redistributing soil and dye.
-
Let the area dry quickly with a fan, then lightly brush to restore the nap if the spot feels stiff; repeat in thin, patient passes rather than flooding the area, which can create halos or texture changes.
-
This solvent-first protocol is standard advice among upholstery pros for S-coded microfiber because water-based methods on these fabrics are a primary cause of visible rings and blotchiness after DIY cleaning.
Guide 4: Handling Stains, Odors, and Texture Without Rings
-
For water-safe (W/WS) fabrics, treat spots with a mild formula after steam preconditioning; apply to a cloth, blot, then follow with a damp towel to lift residue, keeping passes light and airflow high to avoid halos.
-
On S fabrics, use alcohol or a designated solvent in light layers, then brush the nap when dry; never saturate the cushion, and consider inserting a barrier behind removable covers to prevent migration to foam.
-
To manage lingering odors on W/WS fabrics after drying, consider a fabric-safe sanitizing spray as a finishing step, again ensuring the tag allows water-based products and that drying is complete.
-
Between deep cleans, frequent vacuuming and lint-rolling reduce soil load so fewer aggressive interventions are needed later, which helps preserve the even look and soft hand of microfiber.
Guide 5: Drying, Grooming, and Protecting for the Long Run
-
No matter the code, fast drying is half the battle; use fans, open windows, and light towel blotting to reduce dwell time and watermark risk after any wet step, including gentle steam on W/WS fabrics.
-
When the fabric is fully dry, revive the nap with a soft-bristle brush in circular motions to restore the uniform, velvety look that gives microfiber its appeal in high-traffic living rooms.
-
Consider a fabric protector only if the tag allows it and the product passes a colorfastness test on a hidden area; used properly, it can help repel future spills and extend the time between deep cleans.
-
Schedule light maintenance cleans monthly for heavy-use sofas and every few months otherwise, which keeps soils from binding to fibers and reduces the need for intensive spot correction later.

The People
“A former executive told Forbes” would be tidy, but the more useful field rule comes from Carolyn Forté of the Good Housekeeping Institute: “Always start with the gentlest method first and work your way up,” which is exactly how to approach microfiber by code and by risk. Pros and retailers echo the same caution in their how-tos—test in a hidden spot, go low-moisture, and avoid water on S-coded microfiber because consumers often underestimate how quickly rings form and how long they linger.
The Fallout
Analysts now predict based on the new S300 standard’s publication and consumer gadget uptake that mislabeling and method mix-ups will continue to drive service calls for halo and watermark correction after DIY “steam” attempts on S-coded or over-wet WS fabrics. Pro trainers are scaling courses for upholstery cleaning technicians, signaling that demand for certified help is not just a restoration story but a maintenance trend as sofas remain a core, growing slice of U.S. furniture spend.
Look, this smells like a guidance gap as much as a technology boom: the market pushes more “steam” tools while the standard-setter reminds everyone that hot-water extraction isn’t steam, and homeowners still must check a one-letter code before pulling a trigger. If retailers and brands tack clearer care code education onto product pages and delivery packets, the industry could cut preventable returns and preserve microfiber’s reputation for durability and easy upkeep in busy households.
Closing Thought
If the S300 standard catalyzes clearer labeling and better consumer education on W/WS versus S/X and if steam brands emphasize method limits instead of blanket claims will microfiber finally get the low-drama cleaning playbook it deserves, or will another holiday season of water rings keep pro calendars full?
