How to Get Urine Smell Out of Carpet

Why does urine smell linger on the carpet?

As a liquid, urine can seep all the way into the fibres and padding of a carpet. It is usually odourless when it leaves the body, but processes within urine make it smell worse over time.

Dried urine crystallises, which then sticks to carpet and is very difficult to remove. These crystals smell when they're wet, so humid days and steam cleaning can make the smell return. Surface cleaning and vacuuming won't work, as they don't break down the crystals deep within the carpet. Shampoos may mask the odour, but won't remove the crystals. When the shampoo wears off, the smell will return.
