This question is way off topic, for which I apologize. Someone recommended
KO and a tiny bit of research online came up with Peggy Hall as the
creator. I found that she posts to this forum on a regular basis and I'm
hoping she will be able to respond.

I have a situation where cats urinated on the top of a built-in
entertainment center in our basement. The cats have urinated on it for
over a year. I have tried numerous products from Nature's Miracle to
vineager to remove the odor from the wood. I have saturated the wood with
each product. Other than making the odor worse for a number of days I
haven't made any progress in removing the odor. Someone recommended KO. Do
you think KO has a chance of getting rid of the odor? I don't know how KO
works, whether its an enzyme or chemical reaction. If you do think KO
would solve my problem, can you recommend an application rate?

Thanks
Thomas
