The goal in maintaining leather is to keep it oily and mildly acidic, as it is in its original state. The best way to do this is to use mild cleaners and treat it as you would your own skin: clean and moisturized.
Clean leather regularly by applying a lathered, mild soap with very little water. Sponge and rinse often and change the water often as well. A soft toothbrush often comes in handy for hard to reach crevices. Always spot clean bad stains before cleaning the entire leather area.
After cleaning, make sure all soap has been removed by using a sponge and damp water, going over the treated area. As the leather dries, keep it away from direct sunlight.
The mats themselves may need to be changed as often as once per day depending on the traffic. They should also be vacuumed regularly. This prevents dry soil, which gets worked into the mat, from escaping and ending up on the office carpet
