Upholstery Cleaning Guide — What Works for Each Fabric Type

Understanding upholstery cleaning codes

Every upholstered piece of furniture manufactured after 1969 in the US is required by law to carry a cleaning code tag. This code specifies which type of cleaning agent is appropriate for the fabric and is the starting point for any cleaning decision. Ignoring the cleaning code — or using the wrong type of cleaning agent — can result in permanent damage including shrinkage, color bleeding, fiber distortion, and water marking.

The four cleaning codes are: W (water-based cleaning only), S (dry solvent cleaning only), W-S or S/W (either water or solvent-based cleaning), and X (vacuum only — no cleaning products or water). Look for the tag on the underside of cushions or the back or underside of the piece.

When the tag is missing or faded, a professional cleaner performs a fiber burn test and solvent spot test in an inconspicuous area before full cleaning. Never assume synthetic appearance means water-safe chemistry — blends of natural and synthetic yarns can carry unexpected sensitivities that only lab-style identification reveals reliably.

• W: Water-based cleaners only — most common code on synthetic fabrics
• S: Dry solvent (dry cleaning) only — no water; risk of water marking
• W-S: Either water or solvent-based cleaning acceptable
• X: Vacuum only — no water or cleaning products; professional cleaning only

Cotton and linen upholstery

Cotton and linen are natural cellulosic fibers with moderate water tolerance but significant shrinkage risk when over-wet and not dried carefully. For W or W-S coded cotton and linen, spot cleaning with a mild upholstery shampoo applied sparingly with a soft brush, blotted (never rubbed), and dried quickly with a fan is appropriate for fresh stains.

Cotton and linen wrinkle easily when wet and may require fluffing and reshaping while damp. Professional hot water extraction with low moisture and thorough extraction is effective for overall cleaning. These fabrics can also be susceptible to cellulosic browning — a yellowing caused by dissolved soil wicking to the surface as the fabric dries. Professional cleaning with appropriate rinse agents prevents this.

Polyester, nylon, and synthetic upholstery

Synthetic upholstery fabrics (polyester, nylon, olefin/polypropylene, acrylic) are the most water-tolerant and cleanable of the upholstery materials. Most carry a W or W-S code and respond well to mild upholstery cleaners or diluted dish soap solutions. They resist shrinkage and color bleeding and dry relatively quickly.

Professional upholstery cleaning with low-moisture hot water extraction leaves synthetic upholstery clean and fresh with drying times of two to four hours. Microfiber upholstery — a fine polyester weave — requires specific attention: clean with water-based cleaners (if W-coded), dry quickly with a hair dryer on cool setting, and immediately brush with a soft-bristle brush while drying to prevent the fabric from drying flat and losing its texture.

Velvet upholstery, whether synthetic or natural, requires professional cleaning. The pile can be permanently crushed or distorted by incorrect cleaning, and the surface sheen altered by improper product choice.

Wool upholstery

Wool is a protein fiber with high natural soil and stain resistance (due to the naturally waxy lanolin coating on the fiber) but significant sensitivity to heat, alkaline cleaning agents, and mechanical agitation. Wool upholstery typically carries an S or S/W code.

For wool, use dry solvent spotters for oil-based stains and very mild (pH neutral to slightly acidic) water-based cleaners for water-soluble stains. Never use high-pH (alkaline) cleaners — they damage the protein fiber structure. Never agitate vigorously. Professional dry-extraction or low-moisture cleaning by technicians certified in natural fiber cleaning is the appropriate approach for overall cleaning.

Leather upholstery

Leather is not fabric but is frequently confused with synthetic fabric alternatives (pleather, PU leather, bonded leather). Genuine leather requires dedicated leather cleaning and conditioning products — not fabric cleaners, which can strip the finish or cause cracking. Clean leather with a pH-neutral leather cleaner applied with a soft cloth, blot dry, and follow with a leather conditioner to maintain suppleness.

Bonded leather (bonded PU film over split leather or fabric) is significantly less durable than genuine leather and is easily damaged by cleaning products. If the leather is peeling or flaking, it is almost certainly bonded leather and cannot be restored — replacement is the only option. Genuine leather develops patina over time and can be maintained indefinitely with proper care.

• Genuine leather: pH-neutral leather cleaner + leather conditioner; no fabric cleaners
• Bonded leather (peeling): not restorable; replacement is the only option
• Suede: dry-only cleaning; professional suede specialists for significant soiling
• Nubuck: extremely sensitive; professional cleaning only

Frequently asked questions

How often should upholstered furniture be professionally cleaned?

For household furniture in regular use, professional upholstery cleaning every 12-24 months is appropriate. Homes with pets or children may need more frequent cleaning. Like carpet, upholstered furniture traps allergens, skin cells, pet dander, and dust mites — regular cleaning improves indoor air quality and extends the life of the fabric.

Can professional upholstery cleaning damage my furniture?

Improper cleaning absolutely can damage upholstery — this is why cleaning codes and fabric identification matter. A technician who cleans without checking the code and testing the fabric first is taking an unacceptable risk with your furniture. Ask any cleaning company how they identify fabric type and cleaning requirements before agreeing to service.

Is there anything I can do to prevent upholstery from soiling so quickly?

Apply a fluorochemical fabric protectant (like Scotchgard Fabric Protector) after professional cleaning — it creates a barrier that repels oil and water-based stains, giving you more time to blot spills before they set. Establish a no-food policy on upholstered furniture. Rotate and fluff cushions regularly to even out wear and soil accumulation.
