Smooth leather and suede: fundamental differences

Smooth leather (such as that of a jacket or a bag with a shiny or semi-matte surface) has the grain side of the leather facing out: the most compact and resistant surface, generally with a lacquered or pigmented finish on top. This protective layer allows cleaning with some moisture and cleaning products without penetrating the internal fibers of the leather.

Suede, on the other hand, has the flesh side facing out: the internal part of the leather that has been sanded to achieve that soft, velvety texture. This surface has no protective layer, is extremely porous and absorbs any liquid almost instantly. Suede and nubuck (first-grain leather sanded) are the most difficult materials to keep clean because they practically do not allow any wet treatment without leaving marks.

Cleaning stains on smooth leather: correct method

For general dirt, makeup, sweat or scuff stains on smooth leather:

1. Remove excess: if the stain is solid or creamy (cream, makeup), remove it with the tip of a clean cloth without spreading.
2. Clean with leather soap: Leather soap (Saddler's Soap), specific leather soap or a neutral soap with pH 7 applied with a slightly damp cloth is the safest method. Work in small, gentle circular movements.
3. Remove the soap: pass a clean, slightly damp cloth to remove soap residue. Do not leave the leather wet.
4. Dry with a cloth: Eliminate all moisture immediately.
5. Condition: Apply leather conditioner (nutritive cream for leather) to replenish natural oils and restore flexibility. This is especially important after any cleaning.

For oil stains (oil, sunscreen) on smooth leather: apply cornstarch on the fresh stain, let sit for 20 minutes, and wipe off with a soft cloth. Afterward, clean with the previous method. A small amount of 70% isopropyl alcohol can eliminate persistent oil stains, but use very little and condition well afterward because alcohol dries the leather.

Cleaning stains on suede and nubuck: the dry method

The fundamental principle with suede is: avoid water as much as possible. Water moistens the velvety fibers of the suede and makes it clump and look different in that area. A water stain on suede can be more visible than the original stain.

For dry dirt and scuff marks on suede: use a specific eraser for suede (Suede Eraser or white eraser from stationery). Gently rub over the dry stain. The eraser removes surface dirt. Then use a suede brush (with rubber or very fine metal bristles) to lift the nap and restore the velvety texture.

For oil stains on suede: cover with cornstarch, let sit for 30 minutes, and wipe off with a soft brush. If residue remains, apply a specific suede cleaner in foam (Collonil Waterstop Spray or similar) with a very soft brush. The foam cleaner penetrates less than liquid.

Difficult stains on leather and suede

Ink from a ballpoint pen on smooth leather: Apply a very small amount of isopropyl alcohol with a cotton swab, dabbing over the ink without spreading. The ink partially dissolves with the alcohol. Condition well afterward. On suede, ink from a ballpoint pen is practically impossible to remove at home.

Salt (from rain or road) on leather: Salt leaves white marks on wet leather. Moisten the area with warm distilled water, gently rub with a clean cloth to dissolve the salt, and dry immediately. Condition well afterward. Salt dries the leather and can cause cracks over time if not removed.

Water stains on suede: Paradoxically, the solution is to moisten more. Moisten the entire piece evenly with very fine water spray, let it dry evenly away from direct heat, and brush with a suede brush. The localized stain disappears as it dries evenly.

• Do not use solvents (acetone, nail polish remover) on leather or suede: they destroy the material.
• Do not use vinegar on leather: its acidity dries and can fade the dye.
• Do not wet suede with direct water: it leaves permanent marks of different texture.
• Do not use a hot hair dryer to dry leather or suede: the heat hardens and cracks them.
• Do not vigorously rub smooth leather: it can wear down the pigmented finish and leave brighter or discolored areas.
