KLEENCO KITTY SCRAM
This is an amazing malodor counteractant. We use this often when sanitizing vacuum cleaners. The concentrate dilutes to make 8 to 32 gallons of solution.
Kleenco is a family of chemists that bring their knowledge to the public. If you understand the stain you can find a solution to remove it. They make chemicals in concentrate to reduce the packaging cost and so you can save money using your water.
