Remove smell of dog urine from floor tiles?

Try using straight bleach, let it soaK in.BE SURE TO OPEN THE Windows.Then rinse with clean water and rewash with a cleaner like Mr. Clean.

Be sure not use this method on carpet as it has the ability to decrease the longevity of carpet fabric. I've been impressed with some information that I recently found on another site -

You people who are suggesting bleach are off your rockers! YOU CAN KILL YOURSELF! You'll basically be gassing your self with the same stuff the Nazis used in the Gas chambers. Wow.

NaOCl(bleach) + 2NH3(ammonia- a chemical found in urine) --> 2NaONH3 + Cl2(chlorine gas)

It was used as a chemical weapon during World War I and later by Nazi Germany in World War II. If you inhale it, it can be fatal.

Another potential reaction, which occurs when an even greater amount of bleach is added than ammonia, is this:

3NaOCl + NH3 --> 3NaOH + NCl3

That's sodium hydroxide and nitrogen trichloride. Nitrogen trichloride is a very toxic chemical to humans, and even if you did get close enough to ingest it, it would probably explode in your face first, as it is also a very volatile explosive.

I recommend using hot water and vinegar. Then if you dislike the smell it leaves behind, it will then be safe to use bleach, but please be sure that you don't use more bleach than water. To get rid of the vinegar smell i suggest using a regular floor cleaning like Fabulouso or Pine Sol and plug in an air freshner in that area, jsut to be safe.

Thanks for bringing up how bad bleach can be Azriphale. Even need to be careful with the Fabulouso and plug air fresheners. They have so many chemicals in them too. I'd suggest using Freshana. A 100% plant and water-based product that is a miracle worker on urine smells and stains. NOTHING works better and it's safe for people, pets and the environmentally.

A completely unique patented microencapsulation process naturally breaks down the hydrocarbon odor chains. Nothing is masked. The smell is GONE. Freshana
