How to Get The Urine Smell Out of a Mattress

We all know that accidents happen. From a child wetting the bed to a pet peeing in their sleep, mattresses are often subject to urine stains. But if you act quickly, urine is less likely to ruin your mattress or result in lingering odors.

To get urine smells and stains out of a mattress, there are several methods that may help. Simple household cleaners can be used to remove stains and renew your sleep surface, whether the stains are new or existing.

How Do I Get the Urine Smell Out of My Mattress?

If your mattress smells like urine, there are a few different methods to try.

The first method is relatively simple. Remove all bedding, spread a thick layer of baking soda out over the entire mattress, and allow it to sit undisturbed for at least 8 hours. Then vacuum the surface of the mattress, and repeat if necessary.

This process helps remove odors because baking soda is a base that neutralizes acids, including odorous compounds like urine. In the same way that baking soda can absorb unpleasant odors in your fridge or garbage, it can also help freshen up your mattress.

Alternatively, you can use a solution of white vinegar and water. Mix equal parts distilled white vinegar and cold water in a spray bottle. If desired, add a few drops of essential oil for a pleasant smell. Spray this solution over the entire surface of your mattress and allow it to air-dry. Finally, spread a layer of baking soda out over the bed’s surface, allow it to sit for several hours, and then vacuum it.

How Do I Clean Urine From My Mattress?

If the accident happened recently, act as quickly as possible to help reduce the risk of stains and lingering odors.

Strip the Bed

Remove all of your bedding, including sheets and pillowcases. Wash them immediately. If you have a mattress cover or protector, inspect it to see if any urine leaked through to the bed’s surface.

Gather Cleaning Supplies

Gather a few clean towels or rags, white vinegar, baking soda, water, your vacuum, and an empty spray bottle if you have one.

Soak Up the Urine

Using rags or towels, gently blot the affected areas to soak up liquid. Avoid scrubbing, as this can push the urine further into the mattress.

Create your Cleaning Solution

Mix equal parts water and distilled white vinegar. Vinegar is an effective natural cleaning agent that helps neutralize odors.

Apply the Solution

Using a spray bottle, apply your cleaning solution over the affected area of the mattress. If you don’t have a spray bottle, you can use a clean towel, dipping it in the solution and gently blotting the affected area.

Blot Excess Moisture

Using clean towels or paper towels, blot up as much moisture as possible.

Use Baking Soda

Spread a generous layer of baking soda out over the affected area. Let it sit, undisturbed, for at least 8 hours. Baking soda will draw out excess moisture, and it helps neutralize the odors of urine and vinegar.

Vacuum and Inspect

Using your vacuum’s hose attachment, vacuum all of the baking soda off of your mattress. Inspect the bed, checking for signs of odors, stains, and moisture. If necessary, you may need to repeat the cleaning process.

How Do I Remove Existing Urine Stains?

Existing urine stains may require more substantial cleaning solutions. In most cases, a solution of baking soda, hydrogen peroxide, and dish soap should suffice.

In a spray bottle, combine:

  • 8 ounces of hydrogen peroxide
  • 3 tablespoons baking soda
  • 2 to 4 drops of dish soap or liquid laundry detergent

Using the spray bottle, generously apply the solution to the stained areas of the mattress. Allow the solution to soak in, and wait several hours for it to dry. You will start to see a solid layer of baking soda forming on the mattress surface. Once dry, vacuum off the baking soda, and repeat as necessary. If moisture remains, you can spread a layer of baking soda out on the bed to help absorb it.

While hydrogen peroxide can help loosen set-in stains, it can also bleach certain materials, and it may damage or discolor delicate materials like memory foam. To avoid bleaching your bedding, remove any colored materials before using this cleaning solution. If you have a memory foam mattress, you may wish to avoid using a peroxide-based cleaning solution, and instead opt for a commercial enzyme cleaner.
