You take the saddle out of its cover after a few weeks off, and there's a grey bloom on the leather: along the stitching, in the dip of the seat, under the flaps. The musty smell hits you as soon as you open the cover.
Mould starts with damp, and dirty leather only helps it along. Dried sweat and grease from conditioning stay on the surface, and that's where mould grows fastest. All it takes is a few warm days and a saddle that never had the chance to dry.
Below is what we do in our saddle service with mouldy tack: how to remove the bloom without damaging the leather, what you must not use, and what to do when the mould comes back despite cleaning.
Key points at a glance
- Mould appears wherever leather can't dry: under a cover put on a damp saddle, in a closed cupboard, in a tack room with no window or airflow.
- Clean the saddle outside, not in the tack room. Spores spread easily to neighbouring tack, so the first step is to take the saddle out of the room.
- We don't use vinegar, surgical spirit or bleach. They'll lift the bloom, but they strip and dry out the leather, and dried-out leather cracks at the stitching and holes.
- The order is always the same: remove the bloom dry, clean with a leather cleaner, dry at room temperature, and only then condition with balm.
- Once mould has appeared, you can't remove it from leather for good. Cleaning takes it back to zero on the surface; whether it returns depends on the conditions the saddle is kept in.

Where does mould on a saddle come from?
Mould needs three things: moisture, warmth and something to grow on. A saddle offers all three at once, because after a ride the leather is soaked with sweat and the grease from conditioning sits on the surface.
The most common scenario is a saddle put away in its cover before it has had time to dry. The cover traps moisture against the leather and within a few days turns into a humidity chamber. The other typical case is a tack room without ventilation, especially in autumn, when the temperature jumps from day to day.
Day-to-day care matters too. Leather cleaned after riding and kept somewhere dry goes mouldy far less often than tack cleaned once a season. In tack care, consistency is what counts.
How to remove mould from a saddle step by step
The order matters more than the product itself. First you remove the bloom dry, because a damp cloth rubs spores into the pores of the leather; then you clean the leather damp; and you condition it only once it has dried. How long it takes depends on how much moisture the saddle has absorbed and how damp the room is.
1. Take the saddle outside
Spores spread to bridles, saddle pads and neighbouring saddles. Clean outdoors or in a room where you don't keep tack, ideally wearing gloves.
2. Remove the bloom dry
With a dry, soft cloth or a soft-bristle brush, lift the bloom from the surface, the stitching and the corners around the buckles. We do this before any damp cleaning, because wet mould smears and works into the pores of the leather. Afterwards, throw the cloth away or wash it thoroughly at a high temperature to kill the spores.
3. Clean the leather with a leather cleaner
Use a leather cleaner on a slightly damp sponge. The sponge should be damp, not wet, and the saddle is never doused or soaked.
4. Dry at room temperature
No radiators, no hairdryers and no strong sun. Leather dried too quickly goes stiff. Leave the saddle on a rack somewhere airy, without a cover, until the leather is dry in the stitching and creases as well.
5. Condition the leather
Only on clean, dry leather do you apply a thin, even layer of a suitable leather conditioner, chosen according to how dry the leather is and which part of the saddle it is. The order matters here: product applied over bloom that hasn't been removed works the mould deeper into the leather. Cleaning always strips some grease, so this step isn't optional, but we don't apply extra “just in case” either: excess product doesn't soak in and attracts dust over time.
What to clean with, and what to avoid
The most popular home remedies online work on the bloom and on the leather at the same time. Vinegar, surgical spirit, hydrogen peroxide and bleach strip and dry out the leather, and dried-out leather cracks where it works hardest: at the stitching, holes and edges. With vinegar there's also the acid to consider, and vegetable-tanned leather, which most saddles are made from, doesn't cope well with acidity.
Heavy soaking and too much soap are also out: water washes the oils out of the deeper layers, and the saddle then dries unevenly, leaving tide marks and stiff patches.
A safe kit is a leather cleaner, a soft sponge, a soft-bristle brush and a balm or wax to finish. You'll find a ready-made set in the saddle care kit.
What to do when the mould comes back
Let's be clear: you can't remove mould from a saddle once and for all. Spores stay in the pores of the leather and in the stitching. A good clean gets rid of the bloom and the smell, but not the spores themselves, so whether the mould shows up again depends above all on the conditions the saddle is kept in between rides.
So recurring bloom doesn't mean you cleaned the saddle badly. It means either the conditions in the tack room haven't changed, or the mould is sitting where a sponge can't reach: in the stitching, under the flaps and in the panel flocking, where moisture takes longest to dry.
We explain what a saddle is made of in a separate piece on saddle construction. In practice, though, dirt builds up not only on the large, easy-to-reach surfaces but also in the stitching, folds in the leather, around the fittings and in other hard-to-reach spots.
A thorough clean should reach the places a sponge can't. In our workshop we use small tools and accessories that let us clean accessible gaps and corners without taking the saddle apart.
If your saddle needs more detailed care, you can order our saddle leather cleaning and conditioning service, a far more detailed clean than the usual wipe-down after riding. If you're not sure whether it's a job for the workshop yet, start with a saddle assessment; we explain packing and shipping in our guide on how to send a saddle for servicing.
How to store a saddle so the mould doesn't return
Cleaning deals with the effect; the conditions in the tack room decide whether the mould comes back. The saddle must be able to dry after every ride before it goes into its cover.
What matters isn't a single soaking but how long the leather stays damp. That's why closed, stuffy rooms and a cover put on a wet saddle are the real danger, not one rainy training session.
The cover should be breathable, not plastic, and only go on once the tack is dry. The tack room needs ventilation and as steady a temperature as possible, because when a cold night turns into a warm day, moisture condenses on the tack. During a longer break from riding, check the saddle every few weeks. We cover how to look after each part of the saddle day to day in our guide to saddle care.
Common mistakes
The four situations we see most often in the workshop, along with what to do instead.
Mistake: cleaning the saddle in the tack room. Spores settle on the neighbouring tack, and after a while mould turns up on the bridles too. Solution: take the saddle outside and remove the bloom there.
Mistake: damp cleaning without removing the bloom dry first. Wet mould smears across the leather and works into the pores. Solution: a dry cloth and brush first, the sponge only after that.
Mistake: vinegar, surgical spirit or bleach. The bloom comes off, but the leather is stripped and starts cracking a few weeks later. Solution: a product made for leather, and balm once it's dry.
Mistake: drying it by the radiator to have it ready for tomorrow. The leather shrinks unevenly and hardens. Solution: room temperature and airflow.
Frequently asked questions (FAQ)
The questions we hear most often when people bring in mouldy tack.
What should I use to remove mould from saddle leather?
A product made for leather, applied with a slightly damp sponge. Before that, the bloom is removed dry with a cloth and brush, and once the leather has dried it's conditioned with balm. We don't apply balm or wax until the bloom has been removed and the leather is dry, because product applied over mould works it deeper into the leather. Home mixtures with vinegar or spirit remove mould at the leather's expense.
Does mould damage saddle leather?
The bloom itself comes off the surface, but mould breaks down whatever it grows on, and it grows on leather. The longer a saddle stays mouldy and damp, the greater the risk of permanent staining and weakened fibres and stitching.
Will the musty smell go after cleaning?
Usually, yes, if the saddle is cleaned properly and dried completely. If the smell comes back after a few days, moisture or mould has stayed in the stitching or panels and the saddle needs cleaning in the workshop.
Can I use vinegar or surgical spirit?
We advise against it. Both strip and dry out the leather, and you see the effect a few weeks later: the leather stiffens and cracks at the stitching. Mould comes off just as well with a leather cleaner that doesn't damage the material.
How long does a saddle take to dry after cleaning?
As long as it takes for the leather to dry in the stitching and creases too, not just on the surface. Keep the saddle at room temperature, on a rack and without a cover, and don't speed it up with a radiator or hairdryer, as that leaves the leather permanently stiff.
Can mould be removed from a saddle permanently?
No. Spores stay in the pores of the leather and in the stitching, so cleaning keeps mould in check rather than getting rid of it for good. Whether it returns depends above all on how the saddle is stored, and if it keeps reappearing in the same places, it's worth sending the saddle to the workshop for leather cleaning and conditioning.
How should I store a saddle so it doesn't go mouldy?
In a tack room with airflow and a fairly steady temperature, on a rack, in a breathable cover that only goes on once the tack is dry. After riding in the rain, the saddle must dry without its cover before it goes back in place.
Summary
Mould on a saddle looks worse than it is, as long as you act straight away and don't reach for home remedies. The bloom comes off fairly easily, but the mould stays in the leather, so storage conditions decide whether you'll see it again.
The essentials:
- Clean thoroughly: dry first, then with a sponge and leather cleaner.
- Vinegar, surgical spirit and bleach remove mould at the leather's expense, so we don't use them.
- Always dry at room temperature, with no radiator and no cover.
- Mould can't be removed for good: cleaning keeps it in check, and the conditions in the tack room decide whether it returns.
If the bloom keeps coming back or the smell won't shift, bring the saddle to the Equishop Service at ul. Oświęcimska 9 in Ruda Śląska, or send it by courier. For questions about a specific saddle, the quickest way to reach us is our contact page.
