When the urine decomposes, bacteria breaks down the urea—which then releases ammonia. The smell of acid can be temporarily neutralized with baking soda, soap, vinegar, and hydrogen peroxide. But humidity can cause uric acid to recrystallize, and you guessed it—the smell will return.
How do you get the urine smell out of an old house?

That distinctive odor can be an indication of a mold problem. Certain types of mold have a smell similar to cat urine, including dangerous toxic black mold, which should be remediated by a professional. Another source of cat urine odor is ornamental boxwood, a common landscaping shrub.
Wood, by its nature, is porous and will stain and absorb odors. Urine is the most challenging of all odors to remove from wood as ammonia in urine penetrates wood fibers quickly. If it's not wiped up in a hurry, urine decomposes and causes the undiluted ammonia to burn through the wood finish.
Pour the hydrogen peroxide over the stain and then cover it with a clean cloth soaked in hydrogen peroxide. Cover the cloth with plastic wrap, weighting it with a book if necessary. Allow this to sit overnight or for at least 8 hours. The hydrogen peroxide should remove any stains and eliminate the urine odor.
