Please note, these are instructions for regular top grain hide that has a smooth finish, not for suede and distressed leather.
1. Use a brush to remove all salt and dirt residue.
2. Create a mixture of one part vinegar and four parts water.
3. Dip a soft cloth into the water and vinegar mixture and rub a small area of the stain.
4. Dry with a soft cloth or towel then continue with another small area until complete.
5. Let the boots or shoes air dry for at least 30 minutes after you finish cleaning them then check to make sure the stains are gone. They may only show up after the leather has fully dried.
6. Condition the boots or shoes after they've completely dried, using either a natural oil or a specific oil for the type of leather your boots or shoes are made of. Regular conditioning throughout the winter will help strengthen the leather and keep them looking nicer and, most importantly, make them last longer.
