Each winter, the United States uses 18,000 tons of salt on roads and sidewalks. Inevitably, a good portion of that salt will get absorbed into your shoes—leaving otherwise beautiful footwear dried out and stained. It's important to remember that the salt starts drying and warping the leather quickly, so act fast. Here's how to save your shoes:
Make a solution of one part plain white vinegar to two parts water.
Dab the solution onto the stains, working from the outside toward the center of the stain.
Dampen a clean cloth with water and wipe down the shoe to remove any lingering vinegar.
Press a dry cloth into the leather to remove out any residual moisture.
Let them air dry for a day and then condition, buff or polish as usual.
