Professional treatment can significantly improve many pet-urine problems, but complete odor removal depends on how deeply the urine penetrated and how long it has been present. The Carpet and Rug Institute (CRI) notes that urine can penetrate carpet backing and that complete odor removal may be difficult when contamination cannot be fully removed.
Urine salts left in the carpet reactivate when moisture or humidity returns, releasing odor again.
Small accidents may stay in the fibers. Larger or repeated accidents often soak through to the backing and pad, where they are much harder to reach.
Cleaning the top of the carpet does not remove urine below it, so odor can come back after the carpet dries.
Enzyme products break down the organic material in urine. They need proper dwell time and contact with the contamination to work.
Old urine can permanently change carpet dyes and damage backing. In those cases cleaning improves odor but cannot restore the carpet.
Often it can be improved. Results depend on depth and age of the contamination.
Moisture reactivates remaining urine salts, which release odor.
