Carefully remove surface dirt with a damp cloth or brush, then allow the leather to dry at room temperature. Apply a neutral colour cream or polish with a shoe brush and allow it to be absorbed. When dry, polish gently with a soft cloth to generate a sheen.
Extra care should be taken when cleaning suede or nubuck uppers. A suede brush with a suede or nubuck cleaner should remove most stains.
Regular use of protective spray will help guard against staining and water penetration.
