I've got a small dog, and a smallish back yard which is mostly brick-like pavers made of a porus material. The dog pisses on the pavers, and, as it's getting into summer down here, causes an ungodly reek of ammonia (I assume from the breakdown on the ureic acid) after a few days. With my limited chemistry, I've figured that since amonia is an alkaline, that spraying an acid dilution onto the pavers should precipetate out the ammonia. Anyone tried this? Any other sugestions? I don't particularly feel like buying expensive stuff from a pet store when I figure there should be an easy solution to this.
Thanks,
Jeremy
Jeremy, I would spray with diluted white vinegar. You will be left with a vinegary smell, but I like that better than the other.

There used to be a cheap powder called "Odormute" here in the US. I don't know if it's available where you are, but it will neutralize just about any odor. I mixed it up and kept it in a watering can. It's a true neutralizer - left no odor at all. And harmless. I've sprayed it on grass, used it in my laundry, soaked a "skunked" dog in it, etc.

Ask your vet about odor neutralizers, too.

I would try baking soda. Sprinkle on dry and brush in with a broom or brush. If you wet it, I would only wet enough to push some powder down into the cracks. Leave it dry for a while first and see what happens. I used this on carpet at a house where puppies had peed big time. I sprinkled it on and then moved in, sort of grinding the baking soda into the carpet. It killed the odor. I also used it to flush out cat pee smell from an evaporative cooler.
