The E.N. Zyme Solution Stain & Odour Remover is brilliant! I have an aging cat who is becoming incontinent, there's lot's of little clean ups needed around the house quite regularly. Not only is the pee stain and smell gone, it's replaced with a vanilla-like scent and my cat does not like to spend a lot of time in that area anymore. I've been using this spray on the carpet, on furniture, on blankets (so I don't have to wash them every day) and giving the floor a spritz after a clean up. I also tried it on a mattress that was very stained from a large furball being ejected a few years ago - so far have just done one application and 80% of the stain is gone! Next I'm trying it on the front door where the stray cats are marking their territory.
