If you have ever had an indoor pet, sometimes they have a tendency to mark to their territory. If that marked spot happens to be your carpet, then you may notice a stain the spot the spraying occurred and a noticeable smell.
Your best chance to remedy this is to act quickly and blot the stain to try and soak as much of it up as you can. Even if you don’t see it right away, the sooner you attempt to clean it the better. As I mentioned in my last post, you best methods of cleaning the stain are simple mixes of ammonia and water or water and dish soap. You may not be able to completely remove the stain, but you still want to get as most of it out as you can.
For the smell, try a mix of vinegar and water. This is the ideal way to attempt to remove the odors. Your carpet may reek of vinegar for awhile, but it is better than the alternative.
There are also enzyme cleaners out there, which are supposed to break down the urine. I have seen mixed reviews on those. Some people seem to love them and say that they work great, while others say it was only a temporary fix. Temporary meaning that the stains and odors returned after a period of time.
