We recommend using products specifically made for leather care. Leather is a natural material, so it's normal to find small imperfections on the surface and variations in the colour. This is normal, and part of the charm. Do not submerge your leather in water, as doing so could damage the leather and cause it to become brittle.
Our brass hardware will also age over time. If you want to clean it or prefer a shiny appearance, we recommend using brass polish. When doing this, please try to avoid applying any to the leather, as this can cause some discolouration.
