Professional Sofa & Upholstery Cleaning: What Your Fabric Can Take

Carpet cleaning is a fairly predictable job. Upholstery is not. A carpet is one material laid over an underlay on a floor that can take moisture and be dried with airflow. A three-seat sofa is a frame you cannot lift, foam and fibre fill that hold water for days, and a cover chosen by a furniture designer for how it looks in a showroom rather than for how it washes. Two sofas standing in the same room can need opposite methods, and the wrong one does damage that no second clean undoes.

A sofa is not a carpet with arms

Three differences decide everything that follows, and none of them is about how dirty the piece is.

• You cannot lift it. A carpet sits on a floor that tolerates moisture and can be dried from above. A sofa holds whatever goes into it inside foam and fibre fill, in the middle of a room, usually against a wall.
• The cover was not chosen for cleanability. Carpet fibre is specified by people who expect it to be cleaned. Upholstery fabric is specified by furniture designers, which is why linen, viscose velvet and loose weaves end up on seats that get sat on daily.
• It is assembled, not laid. Cover, interliner, fill, webbing and frame are different materials with different reactions to water and pH, stacked a few millimetres apart. The fabric can be perfectly fine while the fill underneath is still wet two days later.

The label on a UK sofa is a fire label, not a cleaning label

Every piece of new upholstered furniture sold in the UK carries a permanent label, but it is not there to tell you how to clean it. Schedule 7 of the Furniture and Furnishings (Fire) (Safety) Regulations 1988 sets out exactly what it must display, in order: the words "CARELESSNESS CAUSES FIRE", the name and postcode of the first UK supplier, the batch or identification number, the date of manufacture or import, a description of all filling materials, a description of all covering materials, and whether the piece includes an interliner that passes the Schedule 3 test. It must be durable, securely attached and legible at 10 point or larger, and in a suite each piece is labelled separately (Schedule 7, legislation.gov.uk).

Cleaning instructions are not on that list. The cleaning code is a separate thing supplied by the manufacturer — on a swing tag, printed under a seat cushion, or sometimes only on the fabric data sheet the retailer holds. So the label everyone finds is the one that tells you about filling materials, and the information that actually decides the method is somewhere else or missing entirely.

The fire label is still worth reading. The "description of all covering materials" line gives you the fibre, and fibre is what the method follows. The interliner line matters too, for a different reason: where a fabric has been given a flame-retardant treatment, a BS 5852 water-soak test demonstrates resistance to a single soak and does not guarantee indefinite resistance to repeated cleaning, so on treated fabrics the number of wet cleans is a question for the treatment provider rather than an assumption (Kothea, fabric care symbols and cleaning codes).

The cleaning codes: W, S, WS and X

Upholstery cleaning codes are a different system from the ISO 3758 care symbols on a garment or a bolt of cloth. The ISO symbols apply to the fabric as a material — washing, bleaching, drying, ironing, dry cleaning. The cleaning codes apply to the fabric as installed, and tell you which cleaning agent is safe on the finished piece. Both matter and neither substitutes for the other (Kothea).

Two things the code does not do. It does not promise a result — it tells you which chemistry will not destroy the fabric, not that a stain will lift. And it does not remove the need for a test: the same reference advises confirming the code on the fabric data sheet before advising a client, and testing any method on an inconspicuous area first, allowing it to dry fully before judging the result. A patch that looks fine while damp is not a pass.

No code at all is common — second-hand pieces, reupholstered frames, imported furniture and anything that has lost its tags. At that point the fibre decides, the test patch stops being optional, and the sensible default is the gentlest method that could work rather than the one that cleans fastest.

What each upholstery fabric can actually take

The fibre sets the ceiling. Everything else — soil level, stain type, how long it has been there — is negotiated underneath it.

Two of those deserve the detail. Viscose is sold under rayon, art silk, artificial silk, bamboo silk and banana silk, and it is all regenerated cellulose — published fibre data is blunt that it loses a great deal of strength when wet and, as a result, stretches and shrinks more than cotton (Swicofil fibre properties). On a sofa that means a damp patch rubbed with a cloth can leave a permanently flattened, dulled or yellowed mark, because the fibres have broken rather than the soil having moved. The full fibre explanation sits in our rug cleaning guide, and it applies identically to a viscose velvet seat cushion.

The other is anything with a jute or natural-fibre backing, or a deck and fill that stay damp. Brown or tan tide marks appearing a day after a clean are usually cellulosic browning — a moisture fault, not a soiling one — and the prevention is always the same three things: neutral-pH products, controlled water volume and forced drying rather than leaving it to the room (Dry Concepts technical note).

Leather: the honest answer before you book

Leather is not a textile and hot-water extraction is the wrong process for it. Soil sits in the finish rather than in a pile, the surface coating is what you are actually cleaning, and the failure mode is a stripped or patchy finish that cannot be put back. Conditioning is a separate job again.

Our carpet and upholstery service is fabric upholstery — sofas, armchairs, dining chairs and headboards. Where a piece is leather, or a fine fabric that needs specialist handling, we will say so at assessment and point you to the right trade rather than take the booking. That is the same position we take on antique rugs and on mattresses that are worn rather than dirty, and it is deliberate. What you can do yourself is set out in our guide to leather sofa cleaning and conditioning — which leather you have, the routine that works, and why the usual advice to condition it twice a year is not as settled as it sounds.

What a professional upholstery clean actually involves

The trade framework is a sequence, and the order is the point. The National Carpet Cleaners Association teaches its advanced upholstery course as five steps — identify, required re-agent, application, removal, rinsing — alongside fibres and construction pH, spotting, fabric protectors and the "so-called delicate and designer fine fabrics" manufacturers now use (NCCA advanced upholstery training). Identification comes first because every later decision depends on it.

In practice, on a domestic visit, that is: inspection and a fibre and colour-fastness test, a thorough pre-vacuum including under and behind the cushions, targeted pre-treatment of marks and the grease line along the headrest and arms, extraction with an eco solution at the moisture level the fabric allows, then grooming and airflow. Allow roughly 30 to 60 minutes of working time for a typical three-seat sofa, which is why upholstery is almost always better value added to a carpet or whole-house visit than booked alone.

We do not publish a single drying figure for upholstery the way we do for carpets, because the fill decides it rather than the fabric — a feather-and-down seat and a high-density foam seat behave completely differently under the same amount of water. The controllable part is how much moisture goes in and how hard it is pulled back out, which is the same principle set out in how long carpet cleaning takes to dry. Over-wetting is the single most common upholstery failure, and it is almost always caused by equipment that puts water in faster than it takes it out.

What sofa and upholstery cleaning costs in the UK

Upholstery is priced per item rather than per room or per hour, and the published UK figures are consistent enough to quote against. The table below is Housekeep's March 2026 cost guide, inclusive of VAT.

• The minimum charge is the figure that catches people out. Most providers set it between £50 and £100 inc. VAT to cover travel, setup and specialist equipment, so a single armchair or a couple of cushions will usually cost the minimum rather than the list price.
• Size is the largest single factor, and some cleaners price per seat instead — typically £15 to £25 per seat.
• Fabric changes the price. Delicate fabrics such as silk, suede and velvet usually need a dry method, which costs more than extraction.
• Out-of-hours, weekend and same-day or next-day bookings cost more, and London typically runs 15 to 20 per cent above the rest of the UK.

The same economics as carpets apply: travel and setup are a fixed cost whatever you book, so a sofa added to a carpet visit is far better value than a sofa on its own. Our carpet cleaning cost guide sets out the per-room side of that, and mattresses are priced on the same per-item basis.

What upholstery cleaning will not fix

Cleaning removes soil. It does not reverse damage, and the distinction is worth having before a quote rather than after.

• Dye damage. Bleach marks, hair-product bleaching on a headrest and old ink are missing colour, not added dirt. Nothing puts the dye back.
• Sun fade. The faded side of a sofa stays faded; a clean usually makes the contrast more obvious rather than less, because the unfaded side comes up brighter.
• Pile crush and seat shape. Years of sitting flatten pile and compress fill. Grooming improves the look of crushed velvet; it does not restore a seat that has lost its shape.
• Collapsed foam or a broken frame. If the seat sags or creaks, the fault is structural and cleaning is the wrong spend.
• Odour coming from the fill rather than the fabric. Where urine, milk or smoke has soaked through the deck into the foam, surface cleaning will improve it temporarily and the smell will come back — the same mechanism explained in our guide to pet urine in carpets.
• Stains that are fibre damage. Some marks have etched, dissolved or permanently dyed the fibre. We will tell you which ones those look like at assessment rather than after the invoice.

What is worth doing between professional cleans

• Vacuum weekly with the upholstery tool, including under and behind the cushions. Most of what dulls a sofa is dry soil that has not yet been ground in, and it is the single highest-value thing on this list.
• Rotate and plump the seat and back cushions so wear and crush are spread rather than concentrated in the one seat everybody uses.
• Blot spills immediately, from the outside of the mark inwards, and never rub. Rubbing moves soil deeper and damages pile and viscose in the same motion.
• Use as little liquid as possible, and never soak. A mark is easier to live with than a water ring or a seat that is damp inside for three days.
• Check the code before any supermarket product goes near the fabric, and test it somewhere hidden first. An S-coded fabric and a water-based foam cleaner is the most common self-inflicted upholstery problem there is.
• Brush velvet pile back in one direction after vacuuming, and keep the sofa out of direct sunlight where the room allows it.

The frequency question is the same as it is for carpets — soiling is not spread evenly, and the sofa that everyone actually sits on earns a clean long before the one in the front room does. Our guidance on how often carpets should be professionally cleaned applies to upholstery on the same logic.

If you would rather tackle a marked seat or a tired cushion yourself first, that is a reasonable thing to want and a W or WS code makes it possible. Our step-by-step method for cleaning a fabric sofa at home covers the dry stage that does most of the work, how to read a test patch, how little liquid you are actually allowed, the drying that decides the result, and the handful of jobs where stopping is the right answer.
