You need an enzymatic cleaner or neutralizer. The biggest brand name is
"Nature's Miracle". You can try petsmart.com to buy it and here
(northeast US) it's also available in most pet stores and even some
supermarkets. Here's the marketing blurb:

" The best-known enzymatic stain and odor remover on the market.
Eliminates urine odors completely with no perfume cover-up odor. Safe
for use around children and pets and on colors because it's non-toxic,
non-flammable, non-caustic and non-acid. Safe for all water-safe surfaces."

FYI it takes 24 hours to break down the odors.

HTH,
