After watching this video I thought it was important to set the record straight on how to treat cat urine in carpet. Tony's heart is in the right place but as a professional carpet cleaner in Tampa FL I have to say his video misses the mark. I'm going to break down each one of his remedies and why you shouldn't use them.
The first cat urine treatment discussed in the video is vinegar and baking soda. This is one of the most popular home remedies I see people use. baking soda is a good deodorizer but it only works while its still in place. In other words once you vacuum up the baking soda the odor will return. Vinegar has a low pH and can be mixed with water to make a weak acid rinse to counter act the higher pH of cat urine, but it can help set the urine in the carpet and make it more difficult to remove. Stay away from this treatment for cat urine.
The second cat urine treatment is peroxide and water. Peroxide is a mild bleaching agent and disinfectant. It can help reduce some of the bacteria in the urine but it can easily bleach carpets, especially if they are older carpets.
The third and final cat urine treatment is Listerine mouth wash added to the first treatment. Mouthwash does have some disinfectant properties but not a lot of cleaning power. If it's not diluted enough it could stain the carpet and do little for removing the cat urine.
I would recommend treating cat urine with a lot of water. I tell people to pour about 4 cups (32oz) of water on urine deposits and soak it all up with a number of dry towels. The effective way to remove cat urine is to rinse it out as soon as possible.
