  • How to clean dried cat urine from a carpet in 5 easy steps

    1. 1

      Protect your hands

      For hygiene, pop on a pair of rubber gloves. If not, make sure you wash your hands thoroughly after going near the cat pee.  According to the Centres for Disease Control and Prevention, touching Toxoplasma-infected excreted matter can cause a host of health issues.[1]

      Clean up the liquid

      If there is any wet urine residue, use an old towel or absorbent paper towels to blot the area of carpet that has cat urine on it. You want to soak up as much liquid as possible. However, never rub urine stains as this will push them further into your carpet.

      Create a cleaning mixture

      Blend together a solution of equal parts white vinegar and water and generously swab the affected area. To avoid any possible damage to your carpet, it’s best to test the mixture on an inconspicuous area first. Leave for 30 minutes.

      Tip: Place an upside down laundry basket over the affected area to stop people walking over it while you’re waiting for the treatment to work. You can also read our article about disinfecting with vinegar and lemons to learn more cleaning hacks.

      Dry the carpet

      Blot the area thoroughly using paper towels or a cloth.

    5. 5

      Check to see if the stain has gone

      Repeat the process as many times as necessary (you may need a few goes to get all of the stain out). You can also read our article about how to clean a carpet without a machine for more tips.

3 other cleaning methods for removing cat urine from carpets

1. Hydrogen peroxide and baking soda

Another effective method for how to get cat urine out of a carpet uses a combination of hydrogen peroxide and baking soda.

Note: Studies have shown that hydrogen peroxide can be an effective disinfectant.[2] So, while you’re getting cat pee out of your carpet, you’re also getting rid of bacteria.

As well as the active ingredients, you’ll need a bowl, washing-up liquid, toothbrush or nail brush and a vacuum cleaner. Hydrogen peroxide can be found in chemists and online – you’ll need the solution labelled as 3 per cent or ‘food grade’. Have your supplies? Here’s what to do:

  1. 1

    Sprinkle the baking soda over the affected area. Add a teaspoon of washing-up liquid to 250ml of hydrogen peroxide.

Pro Tip: Read our article on how to use bicarbonate of soda for cleaning to maximise the benefits of this compound.

  1. 1

    Drizzle this solution over the baking soda and then use a toothbrush or nail brush to work it into the carpet.

  2. 2

    Allow to fully dry, and then vacuum up the sediment. (Remember to change vacuum bags after use so you don’t get stuck with the smell of cat urine in your home.)

2. Sparkling water

This is a useful standby if you don’t have any other ingredients to hand. You’ll just need some bubbly water and a cloth/paper towels.

  1. 1

    Blot the urine using a cloth or paper towels, removing any remaining liquid.

  2. 2

    Pour the sparkling water onto the stain and then dab with paper towels. If you’re using a cloth make sure to continually rotate it to a dry part. It’s important to dab and not rub at the stain.

  3. 3

    Repeat as necessary, and then leave to dry.

3. Commercial cleaners

Do you want to know how to clean dried cat urine from a carpet using commercial products? Well, there are two main types of treatments you can buy at stores or online: oxygen- and enzyme-based cleaners. The latter are especially good at tackling cat pee as they break down the urine and neutralise odours.

Follow the manufacturer’s instructions and remember to first test on an unobtrusive piece of carpet to ensure that there is no damage. Moreover, we recommend reading our guide on how to get rid of bad smells in the house. You’ll learn how to use Cif Anti-Bacterial Wipes to neutralise carpet odours.

Tackling stubborn cat urine stains

If the stain has been there a long time it may require a commercial enzyme cleaner straight off the bat (see above for details). Stubborn marks may require a carpet shampooer (which you can rent). If you can’t budge the stain, it’s time to call in a professional cleaner.

How to remove cat urine smell from carpets

Once you’ve cleaned up the mess, you may then have the problem of a lingering smell, so it’s important to know how to remove cat urine smell from a carpet. Remember that cats have a stronger sense of smell than humans. So, even if you barely notice an odour your cat might and may pee in the same area again.

Enzyme-based cleaners are good at tackling odours (see above). Baking soda also works well – just sprinkle over the affected area and leave overnight before vacuuming it up. (For more useful tips, check out our guide on how to get rid of cat pee smell around the house.)

Why do cats pee on carpets?

If you want to stop cleaning cat urine on carpets, you should get to the root cause of the issue. Ask yourself, “Why does my cat urinate out of the litter box?” Well, various reasons could be behind this problem.

1. Medical problems

While the cats peeing on carpets is not an alarming health problem, it’s still worth considering a visit to the vet. If your pet habitually uses the litter box and then suddenly changes its behaviour, then there could be something wrong with their health. Here are the possible medical issues related to their actions:

2. Poorly maintained litter box

Cats also like to maintain proper hygiene. So, if you neglect cleaning your pet’s litter box, they’ll find a cleaner place to urinate.

3. Incompatible litter type

Cats can also be discriminating when it comes to the type of litter in their box. So, try switching to a different litter to see if that improves their behaviour.

How to stop a cat peeing on carpet

Obviously, it’s better that your feline friend is not peeing on the carpet in the first place.

Your cat pee questions answered

Does vinegar remove cat urine from carpet?

Yes, white vinegar solutions can be effective at cleaning the carpet of cat pee. Simply follow the directions above.

Does cat pee ruin carpet?

Yes, if left untreated there can be long term damage to your carpet as well as the subflooring. Repeated accidents in the same place can cause urine to soak into floorboards, causing them to rot.

Is cat urine bad for your health?

It can be. The strong ammonia odour from untreated urine can affect people with asthma or emphysema, or may trigger allergies.

Bacteria will also grow on the urine which can cause problems such as inflamed airways or skin irritation. Young children or the elderly will be especially sensitive.

In extreme cases, where the urine soaks into the carpet padding, dangerous moulds can form (some of which can cause serious, long-term conditions).

How do you find a urine stain?

The most effective way to tackle a pee stain is to get to it as quickly as possible. However, if you don’t spot it when it’s still wet then it can be easy to miss: look for any discolouration in the carpet.

If you suspect kitty has had an accident but can’t locate it, pull the curtains during the day.  With enough sunlight coming through, it will be easier to spot the stain.

Lastly, you can shine a so-called black light over the carpet. Despite the name, these are ultraviolet lights of the kind used to detect counterfeit bank notes – they are available online or from specialist lighting shops. This will readily highlight any stained areas.
