We’ve all lost a pair of boots to dreaded white salt lines. While the best way to preserve your shoes is to coat them with a protecting spray before the season starts, you can still reverse the salt damage. Mix one tablespoon of white vinegar with one cup of cold water. Dip a cloth into the mixture and rub on the salt stains until they disappear. Let the shoes air dry and there you have it—good as new. (You’ll get better results when the stains are new.) Here’s the best way to clean every kind of shoe in your closet.
