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.
