Cat urine on bark cloth

Has anyone had success removing cat urine stains and odor from
Pacific bark cloth? The stains are old and show a distinct tide line
around the "puddles".  I am considering aqueous methods using the
vacuum table. Are any of the commercial odor removal products such
as mineral rock (zeolite), enzymal, or enzyme/bacteria kits viable
for conservation use?
