Leather is a natural material, which is subject to surface irregularities and slight colour differences. A genuine leather product may also lose colour when wet.
Treat the new leather product with a moisture-protecting spray. This will protect the product from moisture or dirt. Treat the bag regularly with a moisturising conditioner.
Handle the product with clean hands to avoid grease spots. However, if stains do occur, remove them as soon as possible with a cotton cloth. Avoid excessive water, but use a soap suitable for leather, such as Marseille Ecological Soap.
If your leather product gets wet, leave it to dry in peace and quiet, out of direct sunlight. Once dry, you can treat it with a moisturising conditioner. Never scrub a wet leather product, as scrubbing may damage the surface of the leather.
