Leather fails in a specific and predictable way. It is a skin, it contains oils, and the oils migrate out over time through heat, sunlight, body contact and simple evaporation. As they go the hide loses flexibility, and a hide that has lost flexibility cracks at the points where it flexes most — the front edge of the seat cushions and the tops of the arms. By the time you can see cracking, the leather has already been dry for a long while.
That is why cleaning leather and conditioning leather are two halves of one job. Cleaning without conditioning removes soil and also removes some of the remaining surface oil, which leaves the hide drier than it was before you started. Any company that cleans leather and does not condition it afterwards is accelerating the problem they were called in to address.
The other half of doing this properly is identifying the hide first. Pigmented leather has a protective polymer coating and tolerates a reasonable amount of handling. Aniline leather has no coating at all — it is dyed through and the surface is bare hide, so it absorbs whatever touches it, water included. Using a pigmented-leather product on aniline leaves permanent dark patches. The two are easy to tell apart with a simple test and impossible to tell apart by glancing at them.
Step by step
How leather sofa cleaning works
Every stage below is done on every job. The order matters as much as the products.
- 1
Hide identification with a water-drop test
A single drop of water goes on a hidden area — usually the back of the sofa near the floor. If it sits on the surface as a bead, the leather is pigmented and coated. If it darkens the leather and soaks in within a few seconds, it is aniline or semi-aniline and needs completely different handling. Nubuck and suede are identified by the nap. This thirty-second test determines every product used for the rest of the visit.

Dry soil and crevice clearing
Leather traps grit in the seams and in the gap behind the seat cushions, and that grit is abrasive. We vacuum with a soft brush head over the panels and a crevice tool through every seam and fold, and remove the seat cushions to clear the deck. On buttoned or deeply piped leather this is the slowest part of the job and it matters — trapped grit under a cushion cuts the finish every time somebody sits down.
- 3
pH-balanced cleaning, panel by panel
Leather sits at around pH 4.5 to 5.5, mildly acidic. Ordinary household cleaners and most all-purpose sprays are strongly alkaline and strip the finish, which is the most common cause of the dull, patchy look we get called out to fix. We use a pH-balanced leather cleaner applied to a cloth rather than sprayed onto the hide, and work one panel at a time so nothing dries with product still sitting on it.

Attention to the high-contact areas
Head rests, arm tops and the front edge of the seat take the vast majority of the wear. Head rests in particular accumulate hair product and sebum, which build into a dark, slightly tacky film. These areas get a second pass with a soft brush working into the grain, because the soiling sits in the texture rather than on top of it.
- 5
Conditioning and absorption time
A conditioner formulated for the hide type is worked in and given time to absorb. This is not a finish you buff on and wipe off immediately — it needs to penetrate, which takes fifteen to twenty minutes. On dry, thirsty leather we apply a second lighter coat once the first has gone in. On aniline we use a conditioner specific to uncoated hide, because standard pigmented-leather conditioners sit on the surface and leave it looking greasy.
- 6
Buffing to an even finish
The panels are buffed with a clean microfibre cloth to remove any conditioner the leather did not take up. This is what stops the sofa feeling slippery afterwards, and it evens out the sheen so the cleaned panels match. We finish with a protection product on request, which slows the next round of oil loss.
Identifying your leather before anything touches it
The water-drop test settles it in seconds, and the answer changes everything that follows. Here is what each type means in practice.
| Type | How to spot it | How it is cleaned |
|---|---|---|
| Pigmented (protected) | Uniform colour, slight sheen, water beads on the surface. Around 80% of UK sofas. | Most robust. pH-balanced cleaner, full conditioning. Small colour repairs are possible. |
| Semi-aniline | Visible grain, light protective coat, water darkens slowly. | Gentler products, less moisture, conditioner matched to lightly coated hide. |
| Aniline | Natural markings visible, matte, water soaks in within seconds and darkens. | Specialist uncoated-hide products only. No water, no general-purpose cleaner. |
| Nubuck / suede | Velvety nap that changes shade when you brush it. | Dry method with a nap brush and specialist powder. Liquid cleaners ruin it. |
| Bicast / bonded | Very uniform, plastic-like feel; often peels in sheets once aged. | Gentle surface clean only. Bonded leather delaminates and cannot be restored. |
What we can fix, and what needs a restorer
Cleaning and conditioning reverses the things caused by soil and dryness: the greyish film on the arms, the darkened head-rest patches, stiffness, and the dull look that comes from a build-up of old care products. Leather that has gone hard usually softens noticeably once conditioned, because the stiffness is lack of oil rather than damage.
It does not fix physical damage. A tear, a cigarette burn or a cat-scratched arm needs a leather repair technician — a different trade, working with fillers and colour matching. Colour that has rubbed off down to the substrate needs re-pigmenting, which is also restoration rather than cleaning. Bonded leather that has started peeling cannot be saved by anyone: the peeling is the polyurethane layer separating from its fabric backing, and there is nothing underneath to bond it back to.
We will tell you which category your sofa is in before we start, and if it is a restoration job we will say so rather than take a cleaning fee for a result that will not satisfy you.
Why household products damage leather
The three things we most often see used, and what each one does: baby wipes contain surfactants and sometimes alcohol, and repeated use strips the finish in exactly the high-contact areas you were trying to clean. All-purpose sprays are alkaline, typically pH 9 to 11, against leather at pH 5 — that gap dissolves the protective coating. Furniture polish and silicone-based sprays leave a film that looks good for a week, then attracts dust and eventually goes blotchy.
Olive oil and other kitchen oils are a persistent piece of internet advice and a genuinely bad one: food oils go rancid in the hide, and the smell that develops is not removable.
If your sofa has already had these used on it, say so when you book. Stripping old product build-up before cleaning is a step we can plan for, and it changes how long the job takes.
Keeping leather in condition between visits
- Keep the sofa out of direct sunlight, or at least rotate the cushions — UV is the fastest route to faded, brittle hide.
- Keep it at least 30cm from radiators. Dry heat pulls oil out of the hide faster than anything else in a London flat.
- Dust weekly with a dry microfibre cloth. Dust is mildly abrasive once it works into the grain.
- Blot spills immediately with a dry cloth — never rub, and never use a wet one on aniline.
- Vacuum the seams monthly with a crevice tool to clear the grit that does the abrading.
- Have it cleaned and conditioned every 6 to 12 months. Conditioning is preventative, so the interval matters more than it does for fabric.

Questions
Leather sofa cleaning — common questions
How do I know whether my leather is aniline or pigmented?
Put one drop of water on a hidden part of the back of the sofa. If it beads and sits there, the leather is pigmented and has a protective coating. If it soaks in and darkens the spot within a few seconds, it is aniline or semi-aniline. The distinction is not cosmetic — using a pigmented-leather cleaner on aniline leaves permanent dark patches, so we do this test on every visit before opening a bottle.
Can you remove cracks from leather?
No, and we would rather say that plainly. A crack is a physical split in the hide, and cleaning cannot rejoin it. What conditioning does is restore flexibility to the leather around the crack so it does not spread, and the surface usually looks considerably better because the cracks become less visible once the hide is supple and evenly coloured. Repairing existing cracks is a restoration job for a leather repair technician.
Will cleaning restore faded colour?
Cleaning removes the dull grey film of soil and old product, and that alone usually makes leather look significantly richer — people often read this as colour coming back. Genuine UV fading, where the dye itself has broken down, is not reversible by cleaning. That needs re-pigmenting, which is a restoration service.
How often should leather be cleaned and conditioned?
Every 6 to 12 months, and more often for leather near a radiator or in direct sun. The interval matters more than it does with fabric because conditioning is preventative — you are replacing oils before the hide gets dry enough to crack, and once it has cracked no amount of conditioning undoes it.
Is the process safe for a sofa with contrast stitching or piping?
Yes. Contrast stitching is the place where over-wetting shows first, because thread wicks moisture and can carry dye from the leather into a pale stitch. We apply product to the cloth rather than to the sofa, work away from the stitch line, and keep the seams dry — which is also why we do not spray leather directly.
My leather sofa smells musty. Will cleaning fix it?
Usually, if the smell is in the hide and the seams rather than in the foam beneath. Leather holds odour in the grain and the seams, and a thorough clean plus conditioning clears most of it. If the sofa has been stored damp and the foam has taken on mould, the problem is below the leather and cleaning the surface will not solve it — we will tell you that on inspection rather than after taking payment.
