Leather Care

The fundamental reason why leather is soft is that when leather is made, oil is introduced into the interior of animal skin to form an oil film that completely covers the surface of the fibers inside the skin, that is, a layer of oil film with appropriate thickness is used to separate the surface of the fibers inside the skin. In this way, the friction between the fibers inside the leather is equivalent to the friction of the oil molecules, so the leather will be very soft. Its principle is similar to that of sponge, but the difference is that the inner surface fibers of dermis are separated by oil film, which makes the inner surface of dermis have sliding pores, but its pores are smaller than that of sponge, and the distribution of the inner surface fibers of dermis is not as regular as that of sponge.

Leather cleaner is used to clean leather clothes, leather sofas, leather bags, leather chairs, leather shoes and other leather products. Leather cleaning generally refers to the cleaning of the surface of leather products, excluding the cleaning inside.
