I run a nonprofit yorkie rescue and yorkies sometimes use bathroom pads. I would toss them in a sealed tight trash container, and was smelling up the entire house with the contents. I now take a cosmetic sponge (small) soaked in the cocentrate and keep at the bottom of the container, under the bag. No more smelly home! And, when you open the trash to toss something in, there is no gagging smell of mess!Thank you! The smell is strong, but needed strong!
