Prepares the leather for dyeing without damaging the final result. Eliminates dirts, creams and the surface laques that protect the grain of the leather, allowing an excellent fixing of the dye. To obtain better results, we recommend an application with a scouring pad. Soak the pad and rub lightly over the whole surface to dye. The grain of the leather will be clean and will open the leather's pores, allowing the dye to penetrate and fix perfectly. When apllying over synthetic leather, use a cloth, never a scouring pad. Allow to dry before dying. Not suitable for suede and nubuck.
