Avoid contact with abrasive surfaces, keep your product dry and protect it from direct sources of heat (radiators, car interiors in summer) and sunlight to avoid colour fading. Avoid contact with toiletries, cosmetics and sun cream.
To clean your product, wipe it with a soft and dampened cloth. Never use soap or solvent. You may also wish to feed the leather from time to time with a leather wax.
See here for advice on if your leather gets wet.
