As the owner of an elderly cat with bad litter box habits, I've
become a huge fan of Nature's Miracle.  I don't know anything about
its conservation appropriateness, but I do know that almost nothing
else has worked for my laundry items.  The ingredients are vague
(bio-enzymes and oxygen boosters), and the spray I've used smells
like isopropyl alcohol.  The company is probably guarded about
revealing the specific ingredients, but perhaps they would be
agreeable to helping you with conservation questions.  I would be
very interested to hear how the treatment goes.  Good luck (and my
sympathies for such a wretched problem).
