Fast acting, deep penetrating formula containing pure neatsfoot oil and mineral oils that will not rot stitching. Fantastic for softening stiff or new leather, also excellent for restoring leather after storage or prolonged use in rain. Can be used routinely to nourish and rehydrate or as a preventative to avoid drying and cracking. Ensure leather is clean, then apply a thin layer to the flesh side of the leather and allow to soak in. If required, also apply a thin layer to the grain side. Reapply if the leather still appears stiff, taking care not to over-oil. Not suitable for aniline or untreated leather, suede or nubuck. Test on a hidden area before use.
