Why home fabric cleaning is harder than it looks
Sofas, carpets, rugs, mattresses and fabric chairs collect bacteria, dust mites, pet dander, skin cells, mould spores and odour compounds deep in the fibres. A surface spray and wipe deals with what you can see. It does nothing for what’s in the fibre.
The same principle applies whether you’re cleaning a family sofa that’s been through years of use, a carpet with a pet urine stain, a mattress that needs sanitising, or a rental flat that needs turning around between tenancies. You need something that gets into the fibre, lifts the contamination, and brings it back out again. That’s what a spray extraction machine does.
What you need
A spray extraction machine
A spray extraction machine injects diluted cleaning solution under pressure into the fabric fibres, scrubs with a brush head, and simultaneously extracts the dirty solution into a recovery tank. In one pass it does what a spray bottle, a cloth and a wet/dry vacuum do separately — and does it better than all three combined.
V-TUF makes two sizes. The 37L is right for a domestic home or a flat. The 77L is the choice for landlords turning around multiple properties, cleaning contractors, or anyone cleaning large areas of carpet regularly.

A dedicated fabric sanitiser
General purpose cleaners, washing-up liquid and carpet foam products leave residue in fibres that attracts dirt faster after cleaning. A dedicated carpet and upholstery sanitiser is formulated to clean without residue, to be pH-safe on fabric and foam, and to neutralise odour compounds at source rather than mask them with fragrance.
The V-TUF VTC420 is 10x concentrated — dilute to the label specification before use. Do not apply neat to fabric. One 5L bottle, correctly diluted, will clean a lot of upholstery.

A soft brush for agitation
A medium-bristle upholstery brush or soft detailing brush for working cleaning solution into tight areas — sofa cushion seams, carpet edges, the back of fabric chairs. Hard brushes damage fabric fibres over time.
Sofas and fabric chairs
Before you start
Check the fabric care label. Most modern sofas use codes: W (water-based cleaners only), S (solvent-based only), WS (either), X (vacuum only — do not wet clean). The VTC420 is a water-based cleaner. Do not use it on fabrics marked S or X. For most polyester, microfibre, cotton blend and velvet sofas — which covers the majority of UK domestic upholstery — water-based cleaning with a pH-neutral sanitiser is correct.
Test on a hidden area first — the underside of a cushion or the back panel of the sofa. Apply diluted VTC420, leave two minutes, blot dry. If colour transfers to the cloth, stop and seek professional advice.
Step by step
1. Remove all cushions and vacuum the entire sofa including crevices, under cushions and along the base. Use a crevice tool along seams and in the gap between the seat cushion and the back panel — where crumbs, pet hair and bacteria concentrate.
2. Mix VTC420 to the label dilution ratio in a spray bottle or in the solution tank of your SPRAYEX machine.
3. If using a SPRAYEX: attach the upholstery tool, fill the solution tank, and work in overlapping passes across the sofa surface. Work from the top of the back panel downwards and toward you, so you’re not resting against cleaned areas.
4. If using a wet/dry vacuum: spray the diluted solution onto a section, work in with a soft brush in circular motions, and extract with the upholstery nozzle. Work in 30cm x 30cm sections.
5. For heavily soiled areas or visible staining — pet accidents, food spills, grimy armrests — allow the cleaning solution to dwell for three to five minutes before agitating and extracting.
6. Continue until the water in the recovery tank runs close to clear. The first pass on a dirty sofa will produce dark, murky water. By the third pass it should be noticeably lighter.
7. Leave cushions off and allow the sofa to dry completely before replacing them. Open windows and use a fan to speed drying. A damp sofa left in a warm room will develop mould and odour — the opposite of what you cleaned for.
Carpets and rugs
Room carpets
Carpets hold more contamination per square metre than almost any other surface in a home. A heavily used living room carpet in a family home can contain millions of bacteria per square centimetre in the pile. The carpet looks clean. It isn’t.
1. Vacuum first. Thorough vacuuming before wet cleaning is not optional — it prevents loose dirt becoming mud in the extraction tank and being redistributed into the pile.
2. Move furniture off the area to be cleaned or use furniture protector pads under legs.
3. Fill the SPRAYEX solution tank with diluted VTC420 and attach the carpet head. Work in straight overlapping passes, starting from the far corner of the room and working back toward the door so you don’t walk on cleaned carpet.
4. For traffic lanes, doorways and areas in front of sofas — the heaviest-wear zones — make a second pass at 90 degrees to the first.
5. Leave the room until the carpet is dry. In a well-ventilated room in warm weather this takes 2–4 hours. In winter or in a poorly ventilated room, allow longer. Run a dehumidifier if you have one.
6. Do not replace furniture until completely dry — furniture legs on damp carpet will cause rust staining from metal feet or dye transfer from wooden feet.
Rugs
Remove to an outdoor or well-ventilated area if possible. Clean both sides — the underside accumulates as much contamination as the face. Allow to dry flat or hang over a fence in dry weather. Do not return to the room until completely dry.
Pet urine and pet stains
Pet urine in carpet requires extraction, not surface treatment. The urine travels through the pile and into the backing and underlay. Surface spraying with an odour neutraliser treats the smell at the surface while the source of the odour — the crystalised urine in the backing — remains. Extraction pulls the contamination out of the pile. For severe or repeat-soiling incidents, the underlay may need to be replaced regardless of surface cleaning.
Allow the VTC420 solution to dwell for five minutes on pet urine areas before extraction. Multiple passes may be needed. The smell will reduce significantly after cleaning and drying, and continue to improve over 24–48 hours as the remaining moisture fully evaporates.
Mattresses
Mattresses accumulate sweat, skin cells, dust mites and — where children or pets share the bed — urine and other biological contamination. A mattress that smells, has visible staining, or has been slept on by someone who has been unwell, benefits significantly from extraction cleaning.
Use the upholstery attachment on the SPRAYEX or wet/dry vacuum. Keep moisture levels low — the mattress needs to dry fully before being slept on, which takes several hours in a well-ventilated room. Do not use a plastic mattress protector until completely dry.
For significant biological contamination — a child’s bed after a stomach bug, a mattress with long-term pet use, or a mattress being prepared for a new occupant in a rental — two extraction passes with the VTC420 solution are more effective than one.
Office chairs and fabric partitions
Fabric office chairs and acoustic partition panels accumulate the same contamination as domestic upholstery but in a more concentrated way — one person in contact with one chair for eight hours a day, five days a week. Most office chairs are W or WS coded and can be cleaned with water-based extraction. Work with the SPRAYEX upholstery attachment in the same way as a sofa cushion. Allow chairs to dry before use — typically 1–2 hours in a warm office environment with good airflow.
Rental properties and void preparation
Between tenancies, carpets, upholstery and mattresses are the fabric surfaces most likely to carry odour, visible staining and biological contamination. Professional extraction cleaning of all soft furnishings before a new tenancy is significantly more effective than surface spray treatment and is the expected standard for managed rental properties.
The V-TUF SPRAYEX 77L is the choice for landlords or letting agents cleaning multiple properties, or for cleaning contractors taking on end-of-tenancy work. The larger recovery tank means fewer empties between rooms, and the higher motor power maintains suction on heavily soiled carpets over sustained use.

How often should you clean home upholstery and carpets?
For a family home: carpets extraction-cleaned once a year, sofas twice a year. For homes with dogs or cats: carpets every six months, upholstery quarterly. For homes with young children: carpets twice a year, mattresses annually. For rental properties: between every tenancy as standard practice.
The visible test: if you can press a white cloth onto the carpet pile and it comes away discoloured, the carpet needs an extraction clean regardless of how recently it was vacuumed.
