how much of each in a gallon hot water Grant? Have you used for worst case. Do you follow with a deo of some kind?I have had good success with Hydrogen Peroxide on old cat pee. Buy some strong clear peroxide as suggested, mix it with some HOT water and ammonia and apply it. The heat and ammonia will accelerate the rate of decomposition of the peroxide into oxygen and water, this is where your cleaning is done.
