What Is Oiled Leather? Oil-Tanned vs Oiled and Waxed Finishes
Oiled leather is a finish, not a tannage. See how it differs from oil-tanned, pull-up, greasy and waxed leather, and where sources disagree.
Oiled leather is leather that has had oils and waxes worked in as a finish, so it feels softer, looks richer and resists water better. "Oil-tanned" is the looser name boot and shoe makers often use for the same thing, but it is not true oil tanning, the old method behind chamois.
This definition is part of our guide to leather types, textures and finishes. Close relatives have their own pages: pull-up leather, greasy leather, wax leather and Chromexcel.
Tannage or finish?
Tanning is what stops a hide rotting. Oiling comes after it. A bootmaker puts it plainly: the leather is not tanned or preserved with oil, it is finished with it. A leather-craft school agrees that oiled leather is a finishing process, not a tanning process.
Sources differ on what sits underneath. The school says oiled leather usually starts as chrome-tanned leather. Wikipedia says oiling is normally done on full-grain aniline leathers and that vegetable-tanned leather is the type most often oiled. Both can be true of different leathers, so a product's tannage is a separate question to ask the maker.
How the oil gets in
There are two common routes, and sources name them differently.
- Hand oiling: brushed or applied on with a tampon, using a raw oil or a blend of raw and emulsified oils with a penetrating aid. The oils are commonly sulfated castor oil or other sulfated vegetable oils.
- Stuffing in a drum: in hot stuffing, fats and oils that are solid at room temperature are tumbled into the skins in heated barrels. In wet stuffing, emulsified heavier oils and waxes are used.
The purpose is to lubricate the fibres. Dry, unlubricated fibres break very easily, and oil also adds color and some water resistance.
Oiled, oil-tanned, pull-up, greasy, waxed: what each word names
Makers do not use these words the same way. One footwear maker lists "Natural Leather Oiled" and "Waxy Leather" as separate material labels but gives no definition of either on the page we read. Chamois, in the US, is restricted by a federal standard to sheep or lambskin flesh splits tanned solely with oils. See what chamois leather is.
| Word | What it names | Fact |
|---|---|---|
| Oiled leather | A finish: oils and waxes worked into tanned leather | – |
| "Oil-tanned" (boots, shoes) | Usually the same finished leather, loosely named | – |
| True oil tanning | Chamois: oil oxidizes in the skin and makes the aldehydes that tan it | – |
| Pull-up | An effect: color lightens where the leather bends | – |
| Greasy | Full-grain leather impregnated with oil, one maker's term | – |
| Waxed | Wax worked in or applied as a finish | – |
| Chromexcel | One tannery's hot-stuffed, combination-tanned product | – |
What oiled leather is like
A leather-craft school lists these traits: more water and moisture resistant, a rich and sometimes darker look, and creases that show more because the oils shift when the leather bends. It warns that in an unsealed piece the oils and waxes can rub off on other things.
In this video, the leather-craft channel International Leather Club shows oiled leather up close, including a cross-section that shows the darkening the oils cause inside the fibres. Watch the section on how it is made: the channel treats oiling as a finish applied to chrome-tanned leather, which matches the point above.
Does oiling it again help?
Sources disagree. Wikipedia says frequent oiling with mink oil, neatsfoot oil or similar keeps leather supple and improves its lifespan dramatically. The US National Park Service says dressings have no preservative effect, though it accepts dressing items still in use, such as work boots. We do not treat either view as settled.
Where to see a waxed, shifting finish
For a related finish, the crazy horse travel bag from Leather Collection is 1.2-1.4 mm (about 0.05 in) tan cowhide; the store says crazy horse is waxed cowhide where scuffs lighten the surface and folds darken it. It is a waxed finish, not an oiled one.
FAQ
Is oil wax leather good?
It depends on what you need. A leather-craft school lists wear resistance and low cost among its pros, and oils that can rub off an unsealed piece among its cons.
Is oiled leather waterproof?
No source we read says so. Oiling gives some water resistance, and one school calls oiled leather relatively water resistant.
