I've been doing some research to find a way to clean cat urine from my carpet, and various sources say diluted vinegar works well. I've used vinegar as a weed killer, but I'm skeptical it will work as a cleaner. Is there science behind this, or is it an old wives' tale? Can vinegar really be used to clean cat urine from carpeting? Once the vinegar has eliminated the urine, does it rot/spoil causing additional stains/odor?
I use it quite a bit on dog urine in my carpet. I recently purchased a device to remain nameless to help with this, but the white vinegar works well. I wouldn't say it eliminates it, but you'd have to stick you nose it the carpet to smell it.
I soak up as much urine as I can and then drench the area with undiluted vinegar and let it evaporate over a few days.
