How to Clean a Leather Jacket, New or Second Hand

You have brought home a leather jacket that has spent a decade or three in somebody else's wardrobe. It smells of that wardrobe. There is a grey shine on the collar where a neck used to sit, and something has dried on the left cuff. The instinct is to fill a bowl with hot soapy water and get to work.

Do not do that yet.

Leather is skin, and it behaves like skin. Too much water swells it, then dries it hard. Too much heat shrinks it and makes it brittle in a way you cannot undo.

Most of the damage we see on jackets that reach us has nothing to do with age. It was done by somebody trying to help.

This guide covers how to clean a leather jacket properly at home, what changes when the jacket is second hand rather than new, and the handful of situations where the right move is to stop and hand it to somebody else.

Work out what you are actually cleaning

Almost everyone begins in the wrong place. They start scrubbing the outside when the problem is usually somewhere else entirely.

Spend two minutes on this before anything gets wet. Hang the jacket in daylight, near a window, and go over it in sections.

Smooth leather is not suede, and the difference decides everything

Run your palm across the outside. Smooth leather has a finish you can feel, slightly cool, sometimes with a low sheen. Suede and nubuck feel dry and velvety, and they darken when you press them.

If it is suede or nubuck, put the water away. Water marks suede permanently. Those finishes need a brass or rubber suede brush and a suede eraser, worked dry, and nothing else. Everything below is for smooth leather.

The leather is rarely the part that smells

Turn the jacket inside out. The lining is fabric, usually polyester, acetate or cotton, and it has been against somebody's body for years. It holds sweat, smoke and damp far more stubbornly than the hide does.

If the jacket smells and the outside looks fine, you have a lining problem, not a leather problem. Those are cleaned differently, and treating one as the other is how people ruin jackets.

Check the hardware before you commit

Run the zip its full length. Press every popper. Move the buckles. If a zip is seized or a popper will not close, cleaning is the second job, not the first, because water around failing hardware makes rust worse.

How to clean a leather jacket at home, step by step

This is the routine for ordinary grime on smooth leather: dust, body oils, a collar that has gone shiny. It is not for stains that have soaked in, and it is not for mould.

Work in a cool room, out of direct sun, with the jacket flat on a towel.

1. Empty the pockets and brush it down. A soft dry cloth or a horsehair brush, over the whole jacket, following the seams. You will be surprised how much comes off dry.
2. Test in a hidden spot. Inside the hem, or under the collar. Every hide takes water differently and some darken. Wait for it to dry fully before you go further.
3. Make the mildest solution that will work. Warm distilled water with a very small amount of pH-neutral soap. Distilled matters because tap water leaves mineral deposits as it dries.
4. Damp, never wet. Dip a soft cloth, then wring it until no water will drip. If you can squeeze a drop out, it is too wet.
5. Work in small circles, section by section. Collar, then shoulders, then sleeves, then body. Rinse the cloth often, or you are moving dirt around rather than lifting it.
6. Go over it again with a second cloth, clean water only. This lifts the soap residue, which will otherwise dry sticky and attract more dirt.
7. Let it dry on a wide hanger, at room temperature. Away from radiators, away from sunlight, away from the airing cupboard. It will take longer than you expect. Let it.
8. Condition once it is completely dry. A thin coat of leather conditioner, worked in with a cloth, then buffed. Thin is the word. A thick coat sits on the surface and stays tacky.

Two things people get wrong on that last step. Conditioner is not polish and more of it is not better. And mink oil, which gets recommended constantly, darkens leather noticeably and softens it more than some cuts want. Test it somewhere hidden or leave it alone.

Smell and mildew on a second hand jacket

Knowing how to clean a leather jacket that came from a charity shop or an auction is a different skill from cleaning one you bought new. Two problems turn up again and again, and neither is solved by scrubbing harder.

Smell lives in three places: the lining, the padding inside the collar and shoulders, and the leather itself. Only the first is easy.

Air it first, and give it real time

Hang it outside on a dry day, in shade, with a breeze. Not in sun, which fades and dries the hide. Two or three sessions of a few hours each will shift more than any spray, and it costs nothing.

Then work on the lining

• Turn the jacket inside out and hang it that way.
• Sponge the lining with a barely damp cloth and a little mild detergent, concentrating under the arms and around the collar.
• Do not soak it. Water that soaks through the lining reaches the reverse of the leather, which is unfinished and absorbs readily.
• Let it dry completely inside out before turning it back.

For smoke and stubborn must

Put the jacket in a large bag or box with an open tub of bicarbonate of soda, not touching the leather, and leave it for several days. Activated charcoal works the same way. Both absorb odour rather than masking it.

Fabric fresheners are a mistake on leather. They add a scent on top of the old one and the alcohol in some of them dries the hide.

If a jacket still smells strongly of smoke after all of that, the smell is in the leather itself, and that is a specialist job.

Mildew and mould, and why it keeps coming back

Mildew on leather looks like a dusty grey or greenish bloom, often along the shoulders and inside the sleeves. It means the jacket was stored somewhere damp.

Wiping it off does not deal with it. The bloom you can see is the growth; the spores are in the grain and they will return the moment the jacket gets humid again.

• Take it outside before you touch it, so you are not spreading spores through the room.
• Brush the bloom off dry, with a soft brush.
• Wipe the area with a cloth dampened in a weak solution of surgical spirit and water, which kills what the brush left.
• Dry it slowly and completely, then condition, because alcohol strips oils.
• Fix the storage. Mildew is a storage problem wearing a cleaning problem as a disguise.

If the mould has spread across a large area, or the leather has gone soft and dark where it sat, stop. That hide may be compromised underneath, and rubbing at it will take the finish off.

Can you dry clean a leather jacket?

Not at an ordinary high street dry cleaner, no. Standard dry cleaning solvents strip the oils and the finish out of leather, and many high street shops will decline leather outright or quietly send it elsewhere.

What you want is a specialist leather cleaner. They are a different trade. A specialist cleans the hide, then re-oils it and reinstates the finish afterwards, because cleaning always takes something out that has to be put back. That last step is the reason a specialist costs more and is worth it.

Two practical points before you hand anything over:

• Ask whether they clean leather on site or subcontract it. Subcontracting is not automatically bad, but you want to know who is actually doing the work.
• Expect some colour change on an older jacket. A hide that has faded unevenly over decades will not come back perfectly even, and anyone promising otherwise is overselling.

Four times you should stop and get help

Knowing how to clean a leather jacket also means knowing when not to. Most of the damage we see was avoidable, and these are the situations where doing nothing beats doing something.

1. Ink, paint or anything that has soaked in. Solvents that lift ink also lift the finish. This is a specialist job, and the sooner it goes the better.
2. A large oil or grease stain. Cornflour or talc drawn over it for a day can pull a fresh one out. An old one that has spread into the grain will not come out at home.
3. The leather has gone stiff or cracked. Cracking means the fibres have already broken. Conditioner will improve the look but it does not repair the structure, and scrubbing accelerates it.
4. The finish is lifting or flaking. Some jackets have a coating rather than a dyed-through hide. Once that starts to peel, cleaning removes more of it.

And a rule with no exceptions: never put a leather jacket in a washing machine or a tumble dryer. People ask, and the answer is always no. The machine will felt the lining, swell the hide and dry it into a shape roughly two sizes smaller than the one you bought. It cannot be reversed.

What we do before a jacket goes online

Every jacket we list is reclaimed and professionally cleaned and conditioned before it is photographed. That is the work described above, done properly, before you ever see the listing.

After that it is checked by hand at our Doncaster office, and graded. We use one grade, Very Good, and we describe exactly what it means on our grading page: structurally sound, hardware that works, zips that run, poppers that pop, broken fittings replaced, and a sound lining.

Very Good is not new, and we say so. Expect creasing at the elbows and cuffs, softening and shine on high-wear areas, light surface marks, and some slack in decades-old ribbed knit. Anything that cannot reach that standard is not listed at all.

Every jacket is then measured flat and photographed under flat light, with nothing edited to hide the wear. Chest pit to pit, shoulder, sleeve, length and waist. Those five numbers are on every listing, and our size guide explains how to check them against a jacket you already own, which matters because vintage labels tell you almost nothing.

Each one is measured, graded, photographed, packed and posted from Doncaster, with free UK delivery and dispatch within three working days.

Keeping it clean once it is yours

The routine above is a rescue job. Once a jacket is sound, keeping it that way takes very little.

• Wipe it down when it is dirty, not on a schedule. Over-cleaning does more harm than leaving it alone.
• Condition once or twice a year, or when the leather starts to feel dry rather than supple. Winter salt and central heating both pull moisture out.
• Hang it on a wide or padded hanger. Wire hangers put a point through the shoulder that becomes permanent.
• Give it air. Never store leather in a plastic garment bag. It needs to breathe, and plastic traps the moisture that causes the mildew above. Cotton is fine.
• Let it dry naturally if you get caught in rain. Room temperature, on a hanger, away from the radiator. Then condition once dry.
• Store it somewhere dry rather than somewhere cold. Lofts and cellars are where the mildew comes from.

Do that and a jacket that has already lasted thirty years will comfortably do another thirty. Learning how to care for a leather jacket is mostly learning how little it needs.

If you are looking at a second hand jacket and wondering how much work it needs, the honest answer is that it depends entirely on how it was stored, not how old it is. A jacket kept on a hanger in a spare room will need a wipe and a condition. One that spent five years in a damp garage may not be worth saving.

That uncertainty is the reason we do the cleaning before listing rather than after selling. Every jacket in our vintage leather jacket collection has already been through it, whether that is a brown leather jacket, a black one, or a burgundy that turns up far less often second hand.

Each is one of one, in one size, and once it goes it is gone. If you want to know how it should sit on you before you buy, our guide on how a leather jacket should fit covers the measurements that actually decide it.
