Excellent -  if it touches the smell -  it's gone
I've used this for years and wouldn't be with out it.  We have two cats and one in particular seems to want to mark things with her urine.  If AtmosKlear can touch the odor it is absolutely gone.  Also if it is on something you can wash in the washing machine just use about 1/4 to 1/3 cup in the whole wash water & again the smell is totally gone.<br />I've tried MANY other products and nothing else compares.  I also use it in the air to get rid of smoke smell, etc.
