How to Remove Cat Urine from Wooden Floors

Cat urine wood floors

Cat urine stain on wood floor

These six words can strike fear and dread into the hearts of homeowners, and with good reason. Cat urine on wood floors is notoriously difficult to remove. This can be a problem in two main ways. Firstly, the smell of cat urine permeating your home can be unpleasant and embarrassing. Secondly, cat urine on your wood floors can seriously damage your home’s value. Don’t despair! While, removing cat urine from wooden floors can be difficult, you do have options.

Find Cat Urine on Wood Floor

Before you can start to deal with the problem, you need to know exactly where the cat urine is on your wood floor. Happily, detecting the cat urine is straightforward. You can find cat urine with a UV or black light.

In a darkened room, use your UV or backlight to pinpoint the cat urine stain on the wood floor. Now that you know exactly where the stain is, you can take action to remove it.

Remove Cat Urine Stains from Wood Floor

Of course, the very best way to remove cat urine from wood floors is to clean up the mess immediately. However, that is often difficult in practice, as the cat could be naughty while you’re at work or is simply very sneaky about it. So, in cases where your cat has urinated out of the litter box without your immediate knowledge what should you do? Once you’ve located the urine stain you have two main options: household remedies; commercial cleaners.

1. Clean Cat Urine from Wood Floor with Hydrogen Peroxide

The most used home remedy for cat urine on floors is hydrogen peroxide. This can be applied directly to the stain using a soaked rag or paper towel. Alternatively, a solution of 3% hydrogen peroxide, a squirt of washing-up liquid and a pinch of baking soda can be poured directly on the stain. When trying home remedies it is important to apply the solution only to the stained area and check progress every ten minutes. This can help you avoid any discolouration to your floors.

2. Commercial Cat Urine Wood Floor Cleaners

Another way to get rid of cat urine on wood floors is with a commercial pet urine cleaner. There are a number of enzyme cleaners for cat urine. These cleaners can both remove urine stains and help prevent further accidents by removing a smell that animals may find irresistible. Indeed, having one of these cleaners on standby is a good idea for homes with cats. Finally, apply the cleaner following the manufacturer’s instructions.

3. Sand and Seal

There are situations when cleaners cannot help. If left for some time, soaked-in cat urine creates a large black stain. While an enzyme cleaner may remove the odour, the stain is there to stay. In cases like this, your best option is floor sanding. Sanding down and sealing the floor can remove the stain. However, prior to sanding apply an enzyme cleaner to neutralise any dried urine. Otherwise, the heat from the sanding could ‘bake’ the stain into the wood. Not the result you want!
