what is the best thing you can use to kill carpet odors?

Whatever you do, don't steam clean your carpets as that forces the odors deeper into the carpet and eventually they will rise back up to the surface. The best thing to do to remove old stains from pet urine is to use a wet/dry vac with plain water only. The water forces the dirt and stains out of the carpeting. When it has thoroughly dried, try using a good quality pet odor neutralizer which you can purchase in a pet supply store. The worst case scenario is removing the badly stained area altogether and either replacing it with new carpeting or no carpeting at all. Good luck!

My mother in law told me to mixed water with white distilled vinegar. For a few minutes, it will strongly smelled of vinegar then it goes away. It also gets stain out. And I also use this white vinegar to remove the odor in my garbage disposal. One of the best advice my mother in law gave me.

I use Arm & Hammer Carpet Fresh. It seems to work well.

There is a product called "Nature's Miracle" that I swear by. It takes out the odor very nicely, and it is non-toxic. Also, it breaks it down so even your dog can't smell it. This helps in preventing your pup from going in the same place again (when dogs smell where they went, they tend to go there again.) Good luck!!!

Well I have a rug cleaner and I use Resolve Pet stain and Odor eliminator. It works very well. You can use this without a cleaner. Pour some on the stain and scrub with a stiff brush, use a wet washcloth to clean it. Once you have removed the stain you should get some spray from the pet store. I dont know what its called but you spray it where the dog goes and it ditures them from going.

The dog will continue to go on the carpet as long as there is residual odor on there. . . and trust me, even if YOU can't smell it, it's still there and the dog will definetly smell it and continue to use that spot. The best thing to do is either have your carpet replaced, or cleaned professionally, and then get your dog a crate and when you can't watch his every move, put him in the crate or outside. If your dog is a marker (lifts his leg all the time) then you can get a little male doggy wrap, it looks like a denim belt from Petco or Petsmart and put that on him when he's in the house, at least until he's trustworthy. When he lifts his leg, the pad will trap the urine and he will learn to stop lifting because the pad will be uncomfortable when its wet. Consistency is your best bet to getting him housetrained. You'll have to keep an eye on him all the time in order to prevent an accident because just one will set you all the way back to where you started.
