4 Ways You Can Clean Pet Urine Off Decking


Your deck can be a relaxing spot for you and your pets. If you have a puppy, peeing on the deck is inevitable. But if not careful, your pet urine can damage your quality decking board, especially wood deckings. The decking board will absorb urine, causing the material to rot. Apart from that, the odour of the urine can be so irritating that you won’t want to spend time on your deck. To keep the urine from damaging your deckings, clean it immediately. What are ways to clean pet urine off decking? 

There are many ways you can clean your dog or cat urine off your quality decking board. We will examine some of the ways you can do that.

Dilute Pet Urine With Water

To prevent your dog urine from damaging your decking, you need to clean the urine immediately you notice it on your deck. One way to do that is by diluting the urine first. You can use water to dilute dog or cat urine on a quality decking board. Pour the water on top of the urine to prevent it from staining the board. 

Additionally, you can also make use of a bottle spray or a garden hose to dilute your decking with water. After diluting the affected part with water, use a decking brush to scrub the area to remove any urine stain on the deck surface.

Use Soap and Water

If you have a quality decking board like composite decking, you can use soap and water to clean your pet urine off your decking. Composite decking is very easy to clean. If you have a liquid dishwasher at home, you can clean the decking with it. You can dilute the liquid dishwasher with water in a bucket before pouring it on the affected area. Likewise, you can also choose to pour the liquid washer directly on the urine without diluting it.

 Pour the liquid dishwasher on the affected area, ensuring that the liquid soap is free from ammonia. Wash the affected area with the liquid soap and water, and use a water hose to rinse the soap after washing the decking board. The soap will remove the urine stain on the decking board. It will also neutralise any odour of urine on your deck.

Clean Pet Urine With Vinegar 

Vinegar is a natural decking cleaner and very effective in removing stains from quality decking boards. You can use vinegar to clean your pet urine off your decking. Get vinegar from the store and dilute it with water. Then pour the solution on the spot where the urine is and allow the vinegar solution to sit on the decking board for about 30 minutes. 

Next, get a bristle brush and use it to scrub your quality decking board gently. Scrub till the urine stains are off the decking and rinse the deck thoroughly with water. The vinegar not only removes stains from the decking but will also deodorise the urine smell.  

 Use Baking Soda to Clean Pet Urine 

Like vinegar, baking soda is also a natural cleaning agent for quality decking boards. It is good for cleaning pet urine off the decking. Baking soda works by pulling the urine to the surface of your wood decking. So, if your wood deck absorbs your dog urine, the baking soda will pull some of the urine out of the wood. Apart from that, baking soda also works by deodorising urine smell, thereby making your deck very comfortable to stay. 

Get some baking soda and dissolve it in water, then pour it on the affected area. If you don’t want to dissolve the powder in water, you can also sprinkle it on the affected area after diluting the urine with water. Let the baking soda stay on the affected area for about 30 minutes before scrubbing it gently with a decking brush. When the smell and stains are gone, rinse the decking boards with water.


If your pet pees on your deck, you should immediately clean your pet urine off your decking. You can use soap, water, vinegar or baking soda to remove any urine stain on your quality decking board.
