How do you remove the odor of cat urine?
BioKleen makes a great product called Bac-Out. Soak the urine spot with the Bac-Out, wait approx. 20 to 30 minutes and blot it up. The smell will be gone, but the Bac-Out leaves a clean lime scent. It is a fantastic product and has worked for me when everything else I tried did not work. You can probably find at your local green grocery store.
