Lexol-NF protects the very finest leather from the greasy, sticky residue typical of "pure" neatsfoot oil or neatsfoot compounds. There's nothing to trap dirt, discolor clothing or spread to suede or other materials. Solubilized lubricants penetrate easily into wet or dry leather, nourishing and protecting the fibers while they dry. It actually bonds to the fibers to maintain strength, flexibility and durability. Lubricates without saturating, to give leather an elegant finish without darkening.
