Suede
Not finished leather with a texture — a different cut of the hide, porous and undyed at the surface, where even clean water leaves a ring if it is hard.
What not to do
Unsafe
Do not do this. The risk is established, and it is described below.
Suede is uncoated and porous: an agent does not sit on it, and the guide says cleaning agents immediately darken nude leather.
Precautions
- Test on an inconspicuous area first
- Check the manufacturer's instructions

Relied on for: That caustic household cleaners such as soap or dish detergent and any high-pH cleaner must never be used on leather, and that cleaning agents will immediately darken nude leather. (states this directly)
Isopropyl alcohol is unsafe on Suede
Unsafe
Do not do this. The risk is established, and it is described below.
The guide permits odourless mineral spirits as a LAST step on suede and prohibits alcohol outright; the two are not interchangeable.

Relied on for: That cleaners containing alcohol and any strong solvent must never be used on leather, while odourless mineral spirits are named only as the final step for oil on suede after cornstarch. (states this directly)
Water should be avoided for Suede
Best avoided
The available guidance advises against this.
A damp cloth is the most the maker permits, and it warns the colour will darken until it dries. Soaking is not a stronger version of the same thing.

In detail
Suede is the lower split of the hide, distinguished by a nap on both sides, and the trade body treats it as aniline rather than as finished leather: porous, dyed through rather than coated, and described as the most difficult of the leather group to clean. Two properties drive everything. Cleaning agents will immediately darken nude leather, so there is no test-and-see — the first application is the result. And because the material is porous and uncoated, the water itself matters: the guidance specifies DEIONISED water, because hard water containing minerals may cause rings. That is the rare case where the mineral content of an ordinary tap is the failure mode rather than the dirt. The methods are correspondingly restrained. Water-based soil is treated by dampening a cloth, explicitly not soaking, and rubbing gently while feathering the edges outward so no boundary forms. Oil and grease take a different route entirely: cornstarch is placed over the mark and rubbed gently with a finger until it coagulates with the oil, repeated as needed, and only if the mark survives that is a cloth dampened with odourless mineral spirits used. Absorption before solvent, and solvent last.

What works
Dry soil removal is safe on, in specific conditions, Suede
Safe only in specific conditions
This is only appropriate within specific limits. Outside those limits, no claim is made.
Only within these limits:
- A suede brush or any soft-bristled brush, never a metal one
- Brush gently, following the grain of the nap
- Dry — this is the step that comes BEFORE any damp cloth, not instead of drying
The nap is a surface of raised fibres, so the direction of the brush is part of the instruction rather than a refinement of it.

Why
- Suede is explained by Dye migration and colour bleeding
- Suede is explained by Capillary absorption
The lower split of the hide, with nap on both sides. It absorbs from both faces and has no finish on either.

When the obvious answer is wrong
How do I get a grease mark off suede without ruining the nap?
Suede is the porous lower split of the hide with nap on both sides, dyed like aniline and uncoated. The trade guide states that cleaning agents will immediately darken nude leather — there is no cautious first application, because the first application is the result. Water is not a safe alternative either: the guide specifies deionised water because hard water containing minerals may cause rings. And the guide separately prohibits alcohol, strong solvents, high-pH cleaners and dish detergent on leather generally, as incompatible with modern finishes.
A different kind of treatment works: Change the mechanism from dissolving to absorbing. The trade guide's instruction is to place cornstarch directly over the affected area and rub gently with a finger until it coagulates with the oil, repeating as necessary. The powder offers a finer, drier pore network than the suede, so the oil moves upward into it and leaves with it — nothing is dissolved and nothing is carried deeper. Only if the mark is still evident after that is a cloth dampened with odourless mineral spirits used, and it is the last step rather than the first. Where water is unavoidable for a water-based soil, the guide specifies dampening rather than soaking a cloth and feathering the edges outward so no boundary forms, using deionised water so no mineral ring is left behind.
