Sprinkle with baking soda or kitty litter. Let sit over night. Hopefully that will pull out the smell.
In this post I wrote, I tell you what worked really well for cleaning it out of the carpet. I would imagine the same thing would work on wood.
Hi Dawn: I have used a product called Odormute. Pet Supplies Plus used to carry it, but I'm not sure now, and some Walmarts carry it. You can get it online. You need a product that will change the chemical properties of the urine, or an enzyme eater. Also, Odormute will clean the spot. I have used it for years and have not been disappointed. Even on cat pee stains that were over 16 years old under a carpet, through the padding, in a corner and onto the wooden floor. Never knew the cats were using that area:( AC takes care of a lot of smells. Also cleaned and whitened my son's baseball pants. The cats peed on them and I found out a year later (they were in a box ) and the pants came out white and stink free. The stuff seems expensive, but you just use a little bit. It's environmentally safe, you can use it on your pet for skunk smells, and it's made in the USA! Doesn't get any better than that. Good luck with whatever you use.
Hi Dawn, you can try this
Pour the hydrogen peroxide over the stain and then cover it with a clean cloth soaked in hydrogen peroxide. Cover the cloth with plastic wrap, weighting it with a book if necessary. Allow this to sit overnight or for at least 8 hours. The hydrogen peroxide should remove any stains and eliminate the urine odor.
