When a cat sprays urine in the house, or if it misses the litter box, the smell can become overwhelming. The best way neutralise the urine smell in a house is to clean up urine spots as soon as the cat has an accident; however, it is still possible to get rid of the smell even if the urine spots have been in the house for a long time.

    Clean New Urine Spots

  1. 1

    Soak up as much urine as possible as soon as you notice the cat had an accident. Use a white towel to do this so you don't stain your carpet, upholstery or floors with the dyes from a coloured towel.

  2. 2

    Mix one part white vinegar to three parts warm water in a spray bottle. Vinegar will neutralise the ammonia odour in the cat urine.

  3. 3

    Spray this mixture on the carpet, upholstery or flooring and let it set for at least five minutes.

  4. 4

    Blot the mixture with a clean white towel until the surface is dry.

    Remove Old Urine Smells

  1. 1

    Use a black light to find urine stains on the floor or furniture in each room. Urine and bodily fluids are noticeable because they glow under the black light when other lights in the room are turned off.

  2. 2

    Spray a mixture of one part vinegar to one part water onto the spots that glow under the light.

  3. 3

    Blot the area lightly with a clean, white towel. Allow the area to air-dry.

  4. 4

    Shampoo carpets in the room using an enzyme-based cleaner approved for use with your model of shampooer.

  5. 5

    Clean the hard surfaces in the rooms where the urine smell is present. Use a mixture of one part all-purpose cleaner, such as a pine-scented cleaner, and two parts water for hard floors and walls. For the walls, spray the mixture onto the wall and wipe it with a sponge mop.

  6. 6

    Place a bowl of white vinegar in the centre of each room of the house before you leave for the day. Close all the doors. Vinegar is a natural deodoriser.

  7. 7

    Hide boxes of activated charcoal or baking soda in each room of the house. Boxed activated charcoal is available in the fish department at most pet stores. Activated charcoal and baking soda will both absorb odours.

Tips and warnings

  • Applying a fresh coat of paint to the walls can also help to neutralise the cat urine smell.
  • Because the cat urine smell can penetrate fabrics, wash all curtains and other fabrics in the room. Shampoo upholstery and other items.
