Suede is a very difficult material to clean. New suede shoes can be treated with a protective suede spray. Never use water to clean suede. To restore its nap, rub suede with a bath towel, nail brush or suede brush. Dry stains and marks can be removed by gently rubbing with a pencil eraser or fine grit sandpaper on the affected area. If the suede has an oil stain, try using talcum powder to absorb it. Leave the powder on overnight, then use the suede brush to lift the nap. You can apply a small amount of white vinegar to a damp cloth as a last resort for cleaning suede shoes, but be aware that this may leave a vinegar smell; gently rub the surface of the shoe with the cloth, then allow it to air dry. All other stains on suede should be professionally treated.
