Fiebing's 4-Way Care Leather Conditioner is the most complete all-in-one cleaner and conditioner for use on smooth leather.  4-Way Care preserves by waterproofing and replenishing tanning oils; strengthens by coating each leather fiber with a blend of the finest leather oils and waxes; beautifies the finish by coating with waxes which also aid in resisting dirt, and cleans fine leathers - including exotics because it contains leather soap that floats dirt and grime out.  Especially effective on leather upholstery including leather car seats.  Leaves no residue.  Not for use on suede.
