Start by adding the vinegar to the water. Technically, you could use just vinegar but the smell will be very strong and it will last for days. Don't do it. I speak from experience.
Mixing it with the water will help dilute the vinegar a bit and the scent will be much more subtle.
Soak a cotton ball in the solution and start gently dabbing the cotton ball onto the salt stains on your shoes.
You'll see the salt start disappearing immediately.
Notes
Dilute Vinegar Solution: Combining vinegar with water helps to dilute its strong scent while maintaining its effectiveness in removing salt stains from shoes. This ensures a more pleasant odor during and after the cleaning process.
Gentle Application: Use a gentle dabbing motion with the vinegar solution-soaked cotton ball to avoid damaging the material of your shoes. Patience and care will help effectively lift the salt stains without causing any harm.
Regular Maintenance: To prevent the buildup of salt stains on your shoes, make it a habit to clean them regularly, especially during winter or rainy seasons when salt is commonly used for de-icing. Promptly removing salt residue helps preserve the condition and appearance of your footwear.
