General guidance for wheelchair seat and backrest upholstery fabrics (this article does not cover pressure-care cushions). Always follow the care label and operating manual of your specific product — instructions vary between manufacturers.
Know your material — and what harms it
Most wheelchair seat and backrest upholstery is one of a small family of fabrics, and each has its own enemies. Nylon upholstery, common on folding manual chairs, is chosen partly because it is easy to clean — Drive Medical lists 'easy to clean nylon upholstery' among the features of its steel transport wheelchair. Vinyl seats, such as the black vinyl seat on Invacare's XLT, are similarly described by the manufacturer as easy to clean, and they shrug off spills that would soak into woven fabric. Coated fabrics like Dartex — a coated, water-resistant fabric used on many seat covers — sit between the two: wipeable, but the coating itself can be damaged by the wrong chemistry.
The manufacturer's care label is the boss here. MEYRA, in its official upholstery cleaning instructions, recommends neutral detergents (pH 7) for cleaning and warns that acidic (pH 1–6) or alkaline (pH 8–14) detergents can damage plastic components, surface coatings, or adhesive joints. The same warning applies to disinfectants: neutral is recommended, and aggressive chemistry attacks the very parts that hold the upholstery together. Heat is the other universal enemy. MEYRA instructs that covers for seat and back straps and seat cushions should be washed very gently at 30 °C, because higher temperatures can cause shrinkage of cover fabrics — and it rules out tumble drying, ironing, bleaching, and chemical cleaning entirely. Foam parts inside covers should be removed before washing where possible, again because of shrinkage.
A few extra cautions from the same instructions: check upholstery parts and fabrics regularly against their sewn-in care labels, cover loop tapes (the hook-and-loop fastener strips) before washing to avoid surface damage to the fabric — or hand wash if covering them is not possible — and remember that cleaning and care instructions can vary between individual products, so the operating manual of your specific chair wins over any general guide.
MEYRA's instruction sheet also standardises the care symbols you will find sewn into upholstery: very gentle washing at 30 °C or a fine/wool wash for most covers, with some items rated to 60 °C; do not tumble dry; do not iron; do not bleach; no chemical cleaning. Learn to read the label on your own chair and follow it over any general guide — including this one — because fabrics and coatings genuinely differ between products. One more material note: hook-and-loop fastener tapes are rough on fabric. MEYRA instructs that loop tapes must be covered before washing to avoid surface damage, and recommends hand washing where covering them is not possible. Fasten the Velcro closed before a cover goes in the machine; an open strip of hooks will chew the face fabric in a single cycle.
The safe routine clean
For everyday grime, the routine is gentle and repeatable. Start dry: MEYRA's instructions say loose dirt — food residues, hairs around the castors — has to be removed before any detergent solution is applied. A soft brush or vacuum pass over the seat and backrest fabric gets the grit out before it gets ground in. For hair stuck in seat upholstery, a pet brush is a practical tool that maintenance guides recommend.
Then go damp, not wet. For coated fabrics like Dartex, Invacare's service guidance describes wiping with a soft cloth moistened with water containing a neutral detergent — and notes that the fabric itself can be washed at temperatures up to 71 °C (160 °F) using normal detergent, following the manufacturer's instructions. For general seat upholstery, a damp cloth with mild soap, followed by a rinse wipe with clean water, covers most situations. Work the solution into the fabric with a soft cloth or sponge, then rinse thoroughly: soap residue left in the weave attracts dirt faster and can irritate skin on the next long sit.
If the covers are removable, take them off and wash them according to their labels — MEYRA's gentle 30 °C wash — and remove any foam inserts first. If you use a disinfectant, wear gloves, make sure the product is safe for your specific fabric, and rinse it off according to the manufacturer's specification before it dries on. Then air dry completely before the chair goes back into service: damp upholstery against skin is a fast track to odour and fabric breakdown. Never use a hose, pressure washer, or shower on the chair as a shortcut — water forced into bearings, frame tubes, and upholstery fixings causes the kind of damage no amount of cleaning will undo.
Disinfection deserves a careful word. MEYRA permits disinfectants listed by the Robert Koch Institute and recommends neutral (pH 7) products, warning again that acidic or alkaline disinfectants can damage plastic components, surface coatings, or adhesive joints. In practice: choose a product rated safe for your fabric, apply it, let it work for the contact time on its label, and then rinse it off according to the manufacturer's specification rather than letting it dry on. Wear gloves while using any disinfectant, and never mix products. If the chair is shared between users, disinfection between users matters more than it does for a single-user chair — but the chemistry rules do not change.
Deep clean and when to replace
Some soiling needs more than the weekly wipe-down. For persistent contamination on coated fabrics, Invacare's service manual describes treating with alcohols or a turpentine substitute, followed by hot water and detergent — but note the context: that is a reconditioning procedure, not a Tuesday-night routine, and proprietary disinfectants should only be used with the manufacturer's instructions followed. If a stain or odour survives a proper wash and a manufacturer-approved deeper treatment, the fabric is telling you something.
That something is often replacement. MEYRA's instructions are direct: damaged upholstery parts must be replaced. Invacare's reconditioning checklist says the same in workshop language — check that back and seat covers are intact and that Velcro strips stick; torn parts should be exchanged. Look for the specific failure signs: sagging seat fabric that no longer tensions properly, cracked or flaking vinyl, coating peeling off a Dartex-type cover, frayed edges at the mounting points, or hook-and-loop strips that no longer hold. A sagging seat changes the support under you, which is a seating matter, not just a cosmetic one — talk to your wheelchair or seating service rather than living with it.
Replacement covers are usually available from the chair's manufacturer or dealer, and swapping a cover is far cheaper than the problems worn upholstery quietly causes: pressure points from a collapsed seat, hygiene issues from fabric that can no longer be cleaned, and fixings that give way at the wrong moment. Keep a simple habit from the service manuals: a quick visual check of the upholstery whenever you clean the chair, and act on small damage before it becomes a big one.
Build the inspection into the cleaning routine rather than treating it as a separate job. Invacare's service checklist includes back and seat covers alongside the rest of the chair: check that covers are intact and Velcro strips still stick, and exchange torn parts rather than working around them. Pay attention to the mounting points where fabric meets frame — fraying there means the cover is close to letting go. A five-minute look-over each time you clean is enough, and it is the cheapest maintenance a wheelchair gets.
