Odor Eliminator

[lele]

I have read a thread before where someone recommended a odor eliminator that could be added to litter and put in a humidifier as well as put directly on a soiled area. I cannot for the life of me find that thread and I need to order some of it NOW! My unaltered breeding male is squatting in various locations including a chair and peeing (not spraying). Anyones help is appreciated.
