Firstly, clean the leather thoroughly before refreshing the colour or applying care products. Use COLOURLOCK Mild Leather Cleaner against normal degrees of soiling. Cleaning before treating prevents dirt sticking to the leather's surface. Our COLOURLOCK Leather Cleaning Brush effectively removes ingrained dirt (use circular motions and work from seam to seam). After cleaning, it is always best to apply a care product to protect it against general wear and future staining.
