How to Remove Urine Stains From a Mattress

Read time: 5 mins

Accidents happen, and when they involve urine stains on your mattress, it can be a source of stress and embarrassment.

Whether it's a mishap from a child or a pet, knowing how to tackle urine stains effectively is essential for maintaining a clean, hygienic, and fresh-smelling mattress. 

This guide by Coit provides expert tips and DIY solutions for removing urine stains and odors from your mattress, ensuring you a peaceful and clean sleeping environment.

Understanding Urine Stains and Odors

Urine stains on mattresses can be stubborn, especially if they’re not addressed immediately—urine can quickly seep into the fibers, causing unpleasant odors and potential hygiene issues. 

It’s crucial to understand that urine composition can affect the cleaning process. Factors like diet, age, and health can alter the acidity and smell of urine and impact the stain removal method.

Immediate Actions: Responding to Fresh Stains

Blotting the Stain

When dealing with a fresh urine stain, immediately blot up as much liquid as possible using clean, dry towels or paper towels.

Gently press down on the towels to absorb the urine, but avoid rubbing, as this can spread the stain deeper into the mattress.


After blotting, lightly rinse the area with cold water. This helps dilute the urine and prevents it from setting in.

DIY Mattress Stain Removal

Homemade Cleaning Solutions

Vinegar Solution

Mix one part white vinegar with one part water. Vinegar is excellent for breaking down urine's acidic components.

Baking Soda Paste

Create a paste using baking soda and water. Baking soda is a natural deodorizer and can help in absorbing odors.

Application Process

  1. Apply the Solution: Gently apply your chosen cleaner to the stain. Avoid saturating the mattress.
  2. Let it Sit: Allow the solution to sit for 10 to 15 minutes.
  3. Blot Again: After the solution has had time to work, blot the area again to remove the cleaner and the stain.

Deep Cleaning Mattresses

For older or tougher urine stains, a more thorough cleaning may be necessary:

Enzymatic Cleaners

Enzymatic cleaners are particularly effective against urine stains and odors as they break down the urine's chemical structure. Apply as per the instructions and allow it to work its magic.

Steam Cleaning

Steam cleaning is another effective deep-cleaning method, especially for tackling older or tougher urine stains. 

It uses high-temperature steam to penetrate the mattress fibers, breaking down stains and eliminating odors. However, it's crucial to consider the material of your mattress before opting for steam cleaning, as not all materials are suitable for this method.

Suitable Materials for Steam Cleaning

  • Polyester and Polyurethane Foam: These synthetic materials can generally withstand the heat and moisture from steam cleaning.
  • Memory Foam: While memory foam can be steam cleaned, it should be done cautiously and with low moisture to prevent damage.
  • Innerspring Mattresses: These are usually safe for steam cleaning, but avoid overly saturating the mattress.

Materials to Avoid Steam Cleaning

  • Latex Mattresses: The heat from steam cleaning can damage the structure of latex, causing it to degrade or lose its supportive properties.
  • Mattresses with Silk or Wool Toppers: Natural fibers like silk and wool can shrink or get damaged with high heat and moisture.

Natural Cleaning Methods for Mattresses

If you prefer natural solutions for removing stains removal, here are some tips:

  • Sunlight: Sun drying your mattress can help in eliminating bacteria and odors.
  • Essential Oils: Adding a few drops of lavender or tea tree oil to your cleaning solutions can leave a calming, pleasant scent in your home. 

Pet Urine Stain Treatment

Pet urine can be more challenging due to its stronger odor and concentration, which can penetrate deeper into the mattress fibers. 

Enzymatic cleaners are particularly effective on pet stains as they break down the proteins in the urine, eliminating both the stain and odor. Before using any cleaner, it's crucial to do a patch test on a small, inconspicuous area of the mattress to ensure there's no discoloration or damage. 

Addressing pet stains promptly can prevent the urine from seeping further into the mattress, making it easier to clean.

Mattress Hygiene Tips

Regular Vacuuming

Regularly vacuum your mattress to remove dust and allergens, which can accumulate over time and affect air quality and sleep health. 

It's recommended to use a vacuum with a HEPA filter to ensure even the smallest particles are captured, providing a deeper clean.

Mattress Protectors

Using a waterproof mattress protector can prevent future stains and make cleaning easier, while also protecting against dust mites and other allergens. Look for breathable options to maintain comfort and air circulation, which can also help regulate temperature during sleep. 

Regularly washing your mattress protector also contributes significantly to maintaining overall mattress hygiene and longevity.
