pet urine

Is there anything you can do about pet urine on hardwood floors?

I have hardwood floors…I just pulled the carpet off of them and found several dog urine stains. I have no illusions about re-finishing these floors – im sure they are probably ruined. BUT I would like to get them as clean as possible before putting carpet BACK on top of them. Is there anything I can do to reduce the urine smell of the hardwood?

1. Try Peroxide and a cold (not hot, it will set the stain permenantly) on a sponge to remove the odor and color.
2. Windex. spray to soak the stain then bloat with paper towel
3. Try vinager
3. rub a raw potatoe on it
4. a little toothpaste and warm water, and elbow grease
I hope one of those ideas helps out.
