Gently wipe the affected areas with a cloth dampened in the solution. Avoid soaking the leather, as excessive moisture can damage it. After cleaning, allow the shoes to air dry in a well-ventilated area, away from direct sunlight or heat sources. Once dry, apply a leather conditioner to restore moisture and flexibility to the leather.

7. Cleaning Products That Work (and Ones That Can Ruin Leather)

When cleaning leather shoes, it’s important to choose products carefully. White vinegar is effective against mold due to its mild acidity and is safe for leather when used correctly. Rubbing alcohol, diluted with water, can also kill mold spores.
Avoid using bleach or harsh chemicals, as they can discolor and damage leather. Hydrogen peroxide, while effective against mold, can have a bleaching effect. Always test any cleaning solution on a small, inconspicuous area first to ensure it doesn’t affect the leather’s color or finish.
