Winter salt marks respond to a solution of equal parts cool water and white vinegar on a cloth, again applied across the whole affected area rather than in patches. Blot, do not rub. Let it dry fully, brush vigorously, and most of the white bloom will have gone. Once everything is clean and dry, a light even mist of suede protector spray held well back from the shoe will buy you the rest of the season.
Can I put suede shoes in the washing machine?
No — and this is the one rule worth being strict about. A machine cycle soaks the leather, strips the natural oils, hardens it as it dries and permanently flattens the nap, and the glues holding the sole can give way as well. If the inside of a pair of suede trainers has become unpleasant, deal with that separately: remove the insoles, wash those by hand or replace them, and sprinkle bicarbonate of soda inside the shoe overnight before shaking it out.
How do I stop salt stains in the first place?
Protector spray before the first wear, repeated every few weeks through the wet months, is the single most effective habit — it does not make suede waterproof, but it buys you time to get home. Beyond that, brush your boots down the evening you wear them in bad weather rather than three weeks later, because salt that sits on the fibres keeps drawing moisture and dries them out. Rotating two pairs so each gets a full day to dry out properly will extend the life of both far more than any product will.
