I need a urine odor eliminator that WORKS and is AFFORDABLE!! I need to do a lot of carpets. I know someone on here was talking about vinegar and water mixture. Does that work to make the cat stop going on the carpet or does it just make it so we can't smell it? Also what is the ratio between vinegar and water and what is the best way to use that solution? I have looked at the nok out website also. Has anyone here used that? Does it really work?
