On icy winter days, many cold-weather cities sprinkle roads with salt to melt the ice and make the roads safe. That's good news for commuters but bad news for your suede shoes. Road salt makes suede shoes look warped and dried out, and the ice and snow don't do them any favors, either. Before giving your shoes up as a lost cause, try treating the salt stain with plain vinegar.
Brush the nap of your shoes with a suede brush to remove as much road salt as possible.
Combine one part white vinegar with two parts water. Stir well.
Dip a washcloth in the vinegar solution, then wring it out.
Dab the salt stain with the cloth. Work your way from the outside of the stain to the center.
Moisten another cloth with clean water, then blot the treated area to remove excess vinegar.
Blot the shoe with a dry cloth, then allow it to air dry. Once dry, use circular motions to brush the shoe using a suede brush and to make the nap look like new.
