Thanks, Some very good ideas here for me to try.
Hi Ginger: I think the discoloration may be there to stay, but for the smell, I have used a product called Odormute. Pet Supplies Plus used to carry it, but I'm not sure now. 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.
use odor killing enzymes Nok Out, Urine Off, and Anti-Icky Poo do not spray on it needs dumps on areas then let dry to work. the urine soaks into wood “Spraying” doesn’t work. Dousing, pouring, and soaking are required when cleaning up urine.
To properly use an enzyme cleaner on a fresh or old urine stain:
1. Blot up as much of the urine as you can before applying anything.
2. Soak the affected area with the enzyme cleaner.
3. Let the enzyme cleaner sit for 10 to 15 minutes.
4. Blot up as much of the enzyme cleaner as possible.
5. Leave the enzyme cleaner to air dry.
