Cat Urine saturated wood floors. Need suggestions - This Old House

Can anyone help me with cat urine stains and smell on hardwood floors?

If you have both a cat and wood floors, you might eventually need to know how to remove from the floorboards. The floor may seem clean, but urine can seep between the boards or beneath cracks in the sealant if their are any. This will allow odors to reappear later due to moisture or other causes. Additionally, cats will often pee in the same spot repeatedly if their scent is still left behind, making the problem worse in the future. Fresh messes will be easier to clean up completely than set-in , and whether or not the urine has been able to seep in under the sealant will determine how hard the odors are to remove.

I had this problem last year after I moved to the East Coast. My cat didn't handle the move well and messed everywhere except his litter box. I tried everything on my wood floors and area rugs that was recommended by a large number of wonderful members of Thriftyfun. Nothing worked completely until I read the hint about Listerine. I believe it was to fill a spray bottle half with Listerine and half with water. I sprayed it wherever he had 'visited' and it worked like a charm without harming my wood floors. After that, I confined him to the bathroom for a few weeks and when he was finally 'paroled', he was cured. Good luck to you. I would caution about using bleach near urine, though.

I live in a little town in Oklahoma and I went to a small Janitorial supply store here and they actually had what I was looking for Enzyme D.
