Shampooing (extracting) a carpet contaminated with urine will remove large amounts but not all of the urea salt. Even using a treatment called acid wash will not remove all of the urea salt though it can remove most of the salt and a great deal more dirt.
Washing flooring will also remove much of the urea salt, but flooring has an additional dimension which must be considered. Almost all wood flooring material uses a tongue and groove design to hold the boards together after being installed. The small cracks between adjacent boards allow the urine, while in liquid form, to run into the cracks and dry, leaving the dreaded urea salt in the cracks. Particle board and OSB flooring takes this problem to the limit with hundreds of tiny cracks per square inch. And though the cracks are rather small you have to count them all. Washing all of the soluble urea salt out of all these cracks and the pores in the wood is simply not going to happen regardless of how well you wash the flooring or what cleaning agent you use.
Concrete flooring, despite its hard appearance, is porous. If water can seep though a concrete wall or floor, you can bet that urine can and does the same. Concrete covered with tile presents an interesting problem because there are gaps between the tile and cavities between the tile and the concrete. These gaps and cavities can and will harbor large amounts of odor causing material.
Finally, because it takes very little urea salt to produce large amounts of mercaptan (the odor), additional treatment alternatives must be considered.
