How to get salt stains out of suede and leather boots

What the white lines are

Road and pavement de-icers are mostly salts. Iowa State University Extension notes that most de-icing products sold are chloride-based: sodium, calcium, potassium or magnesium chloride. Slush carries them into the leather, and as the water dries out it leaves the salt behind as a white line where the slush sat. The sooner you deal with it, the less work it is, which is why the card has a “just got in” version.

Smooth leather, step by step

1. Brush or wipe off loose salt and grit as soon as you are indoors. Dr. Martens’ winter guide puts it simply: brush or wipe away salt and grit and let the boots dry naturally.
2. Start with the gentlest thing. LOWA says water with a light soapy solution is usually enough for smooth leather. Dab it on with a soft cloth.
3. For a line that stays, Tory Burch’s care tip is a solution of equal parts white vinegar and water, dabbed on the stain, then a wipe with a cloth soaked in clean water. Blundstone gives a 3:1 water-to-vinegar mix for leather boots that are really dirty. Either way, test it inside the heel first.
4. Dry at room temperature, stuffed loosely with newspaper or with shoe trees inside. Red Wing says to let boots air dry at room temperature, and LOWA says to change the paper every day until they are dry, but not to pack it in so tightly that the shoe warps.
5. Feed and reproof. Once the leather is dry, put back cream or wax, then protector. Red Wing says to reapply protector every few weeks or after heavy rain or mud.

Suede and nubuck

Napped leathers need the opposite order to smooth leather: dry first, liquid last. LOWA warns that salt marks on suede are usually more stubborn, and recommends a combination brush with plastic and brass bristles plus a special eraser, on suede only, because the bristles can scratch smooth leather.

1. Let the boots dry completely. Dr. Martens says not to get suede too wet and to leave it to dry naturally.
2. Brush the dried salt out of the nap, then rub what is left with a suede eraser.
3. Still white? Blundstone dips the corner of a cloth into white vinegar and dabs the stain, taking care not to soak the boot, then lets it dry, brushes with the nap and finishes with the eraser.
4. For nubuck, Red Wing’s method is an eraser bar on the mark, wetted and repeated if the stain persists, then a bristle brush once dry to restore the nap.

Canvas, knit, patent and rubber

Fabric boots and trainers can be hand-washed: a soft brush, mild soap and cool water. Nike advises against hot water, the washing machine and the tumble dryer for its shoes; Allbirds says most of its shoes can go on a gentle, cold machine cycle. Patent leather just needs a wipe with a damp cloth and a buff with patent cleaner (Dr. Martens). Rubber and EVA boots rinse clean; Crocs says to air dry only and to keep them out of extreme heat, which can make them shrink or warp.

Why not just put them on the radiator?

Because every maker we checked says not to. Red Wing’s European care FAQ says intense heat dries leather out too fast, so it cracks, stiffens and loses its natural oils. Hanwag says heat makes leather brittle, can affect the bonding, and shrinks leather. LOWA puts it more dramatically: wet leather can “burn” by a radiator or oven, causing irreparable cracks. Meindl and R.M. Williams say the same. Slow drying takes longer, but a cracked pair stays cracked. If you travel for Thanksgiving on Thursday 26 November 2026, or over Christmas, pack a brush and some newspaper rather than trusting the hotel radiator.

Keep the next stain off

• Proof before the first wet day. Red Wing says to mist its protector from six to eight inches (about 15 to 20 cm) away in a sweeping motion. Blundstone says its waterproofing spray protects from water and stains, salt stains included.
• Top up through the winter. Dr. Martens says to keep boots topped up with protective waxes, balsams and sprays.
• Wipe salt off the same day, before it dries into a line.
• Use shoe trees. R.M. Williams says they let boots dry completely without distortion; Red Wing says they help prevent creasing.
• Waterproof-lined boots: Hanwag warns that newsprint can damage Gore-Tex membranes, so use plain paper or a towel inside those instead of newspaper.
• Rotate pairs so each one has a full day to dry.

Common mistakes

• Scrubbing wet suede. Dr. Martens says not to get suede too wet. Let it dry, then brush.
• Treating only the line on smooth leather. Finish with a clean damp wipe over the whole panel so it dries to one shade.
• Polishing damp leather. Wait until it is fully dry.
• Using a suede brass brush on smooth leather, which LOWA warns can scratch it.
• Packing paper in tightly, which LOWA says can warp the shoe.

For other winter problems, such as water marks, squeaks after a wet walk or boots that smell after a week of slush, use the shoe problem fixer or the squeaky shoes guide.
