Mattes Sheepskin Melp Wash works strongly against soiling, but is gentle on the environment: MELP is biodegradable and a mixture of selected detergents and fatliquors. The highly concentrated wash is moisturizing and ensures that the elasticity and functionality of the wool, as well as the leather, are fully retained - even after many washes. The special wash is also ideal for cleaning washable leather products, including riding breeches.
