Urine odour, whether human or animal in nature, has a strong, distinct smell. If urine seeps into wood, such as wood flooring, the smell can linger for weeks. In some cases, the urine smell can be so strong that the only solution to remove the urine smell from wood is to refinish the wood surface. However, before taking such drastic measures, start by trying to remove the urine smell with common household products.
Locate the source of the urine smell. If you find a fresh spot, blot up with an absorbent rag or paper towels. Be sure to clean up all the urine you can in this manner before proceeding to the next step.
Spray an enzyme-based cleaning solution directly on the urine spot; be sure to cover the entire spot, saturating the area. Enzyme-based cleaners need time to work, breaking down the uric acid crystals, the source of the odour and stain.
Place cling film over the soiled area; this is to ensure concentration of the enzyme-based cleaner. Allow the cleaner to set on the spot overnight.
Remove cling film and rinse the area with clean water. Dab with an absorbent rag or paper towels and allow the area to then air-dry.
You may need to follow this process two times to fully remove the urine smell. If the urine spot is the result of an accident your pet had, provide plenty of drinking water. Urine that is less concentrated produces less odour. Use a fan on the urine spot to speed drying time.
