Need some help here. Tenant moved out of rental unit but left behind an apartment smelling of cat urine. Have tried a mixture of listerine and vinegar but didn,t help. Trying to avoid a costly way so if theres another way before the costly way please help. Thanks in advance.
I agree with Urbantigers 79. Mix a solution of 10% biological (enzymatic) washing powder with warm water for cleaning, rinse thoroughly with cold water, blot dry, then spray with surgical spirit and work this in with a nail brush.
Another suggestion is one tablespoon of Napisan and one tablespoon of biological washing powder to one pint of water. Test this method on a hidden area first, as it may not be colourfast on more delicate carpet or fabric.
The link below has lots of information about the most effective methods of cleaning cat urine from all types of flooring.
