Leather hides that have been neglected for years can still be saved with Leather Rejuvenator. Typical lanolin-based leather conditioners have trouble reaching the leather's deep fibers. Leather Rejuvenator contains natural penetrating oils that nourish these deep fibers, restoring your leather's suppleness. An excellent choice for neglected, vat-dyed leather. For spray-on dyed leather, let Leather Rejuvenator soak in longer. (Most of the leather's pores are sealed by the dye.) Highly concentrated so a small amount goes a long way. Best if applied with our Blue Detail Sponge.
