Assess the Damage

Check for any immediate stains or discoloration

When dealing with urine on a memory foam mattress, it's essential to assess the extent of the damage before proceeding with the cleaning process. Start by checking the affected area for any visible stains or discoloration. Urine can leave behind unsightly marks that may require specific treatments to remove. Take note of the size and severity of the stains to determine the best course of action.

Determine the extent of the urine penetration

In addition to checking for stains, it's crucial to assess how deeply the urine has penetrated into the memory foam mattress. Urine can seep into the mattress layers and linger, causing not only odor but also potential damage to the materials. Gently press on the affected area to check for any wetness or signs of urine penetration. This step will help you understand the level of cleaning and deodorizing required to fully eliminate the urine and its odor.

Remove Excess Urine

Blot the affected area with paper towels or clean cloth

Before starting the cleaning process, it's crucial to remove any excess urine from the surface of the memory foam mattress. Quickly grab some paper towels or a clean cloth and gently blot the affected area to soak up as much liquid as possible. Avoid rubbing or scrubbing vigorously, as this can spread the urine further into the mattress.

Use a wet/dry vacuum for larger urine spills

For larger urine spills or areas with deep penetration, using a wet/dry vacuum can be incredibly effective. This powerful tool is designed to extract liquids from various surfaces, including mattresses. Connect the appropriate attachment to the vacuum and carefully go over the affected area, ensuring that the machine effectively sucks up as much urine as possible. This step will help prepare the mattress for the subsequent cleaning process.

Neutralize the Odor

Create a vinegar solution

Vinegar is a natural and effective odor neutralizer that can help eliminate the smell of urine from a memory foam mattress. To create a vinegar solution, mix equal parts of white vinegar and water in a spray bottle. The acidic properties of vinegar help break down and neutralize the urine molecules, effectively eliminating the odor.

Spray the vinegar solution onto the affected area

Once the vinegar solution is prepared, generously spray it onto the affected area of the mattress. Make sure to cover the entire stain and any surrounding areas where urine may have spread. The vinegar solution will begin to work on neutralizing the odor-causing compounds and breaking down the urine stains.

Allow the solution to sit for a few minutes

To ensure the vinegar solution has enough time to penetrate the mattress and neutralize the odor, allow it to sit for a few minutes. This brief waiting period will enhance the effectiveness of the vinegar in eliminating the smell of urine. While you wait, it's a good idea to open windows or turn on a fan to promote airflow and aid in the drying process.

Blot the vinegar solution with paper towels or a clean cloth

After the vinegar solution has had time to work its magic, it's time to blot it up along with any remaining urine. Grab some fresh paper towels or a clean cloth and gently blot the affected area. Press down firmly to absorb the vinegar solution and any residual urine. Repeat this process as necessary until the area feels dry and odor-free.

Clean the Stain

Prepare a cleaning solution

To tackle the urine stain on your memory foam mattress, you'll need to prepare a cleaning solution. In a clean bowl or container, mix together a small amount of mild liquid soap or detergent with warm water. Stir the solution until it becomes soapy but not overly frothy. This gentle cleaning mixture will effectively break down the urine stain without causing additional damage to the mattress.

Apply the cleaning solution to the stained area

Using a clean cloth or sponge, dip it into the soapy water solution and gently apply it to the urine stain. Make sure to cover the entire stained area without oversaturating the mattress. The mild soap or detergent will help loosen the stain and allow for easier removal.

Gently scrub the mattress using a soft-bristled brush

To further aid in the stain removal process, use a soft-bristled brush to gently scrub the mattress in circular motions. Be careful not to exert too much force, as this can damage the memory foam. The gentle scrubbing action will help lift the stain and allow the cleaning solution to penetrate deeper into the mattress.

Blot the area with clean cloth or paper towels to remove excess moisture

After scrubbing the stain, use a clean cloth or paper towels to blot the area and remove any excess moisture. Press down gently to absorb the cleaning solution and any remaining traces of urine. Continue blotting until the area feels mostly dry and free from stains.

Dry the Mattress

Absorb remaining moisture with baking soda

To ensure the mattress is thoroughly dried and to eliminate any lingering odors, sprinkle a generous amount of baking soda over the surface. Baking soda is an excellent natural deodorizer and moisture absorber. Allow the baking soda to sit on the mattress for a few hours, or ideally overnight, to fully absorb any remaining moisture and odors.

Leave the mattress to air dry

To expedite the drying process, it's best to leave the mattress exposed to air. Find a well-ventilated area in your home where you can place the mattress. If possible, prop it up against a wall or a sturdy surface to allow for increased airflow. This will help speed up the evaporation process and ensure that your mattress dries completely.

Use a fan or open windows to enhance airflow

To further enhance the airflow around the mattress, turn on a fan or open windows in the room where it is drying. Increased ventilation will promote faster drying and prevent any moisture from getting trapped within the mattress layers. Make sure there is no direct heat or sunlight on the mattress, as this can damage the memory foam.

Vacuum the mattress surface to remove baking soda residue

Once the mattress is completely dry, use a vacuum cleaner with an upholstery attachment to remove the baking soda residue. Gently go over the surface of the mattress, ensuring that all of the baking soda particles are effectively removed. This final step will leave your mattress clean, fresh, and free from any trace of urine odors.

Deodorize the Mattress

Sprinkle baking soda over the mattress surface

If you still detect any lingering odors after the initial drying process, it's time to deodorize your memory foam mattress. Begin by sprinkling a generous amount of baking soda over the entire mattress surface. Baking soda is a natural deodorizer that helps absorb unpleasant smells.

Allow the baking soda to sit for several hours or overnight

To maximize the deodorizing potential of the baking soda, allow it to sit on the mattress for several hours or overnight. The longer the baking soda has to work, the better it will absorb any remaining odors. Keep the mattress in a well-ventilated room or area during this process to aid in odor removal.

Vacuum the mattress to remove the baking soda

Once the baking soda has had sufficient time to absorb odors, use a vacuum cleaner with an upholstery attachment to thoroughly remove the baking soda from the mattress. Slowly go over the entire surface, ensuring that all traces of baking soda are effectively sucked up. This step will leave your mattress smelling fresh and clean.

Consider using an odor neutralizer spray

If the urine odor persists even after using baking soda, you may want to consider using an odor neutralizer spray specifically designed for mattresses. Look for a product that is safe for memory foam and follow the manufacturer's instructions for application. A good quality odor neutralizer can help eliminate any remaining smells and leave your mattress smelling fresh for longer.

Prevent Future Accidents

Use a waterproof mattress cover or protector

To prevent future urine accidents from seeping into your memory foam mattress, invest in a high-quality waterproof mattress cover or protector. These protective barriers create a barrier between the mattress and any potential spills or accidents. They are easy to clean and can significantly extend the lifespan of your mattress.

Train pets or children to avoid accidents on the bed

If you have pets or young children, it's essential to train them to avoid having accidents on the bed. This can be achieved through consistent positive reinforcement and proper potty training. For pets, consider using crate training or installing baby gates to restrict their access to certain areas of the house. Similarly, for children, establish a routine for bathroom visits and encourage them to use the toilet before bedtime.

Promptly address any spills or stains to prevent odor buildup

To prevent the buildup of unpleasant odors, it's crucial to address any spills or stains promptly. Accidents happen, but taking immediate action can minimize the chances of urine penetrating the memory foam mattress. When spills occur, use the aforementioned cleaning methods to remove the stain and neutralize the odor as soon as possible.

Professional Cleaning Services

Consider hiring professional mattress cleaning services

If you're facing persistent urine odors or stains that cannot be effectively removed with at-home methods, it might be time to consider hiring professional mattress cleaning services. Professional cleaners have specialized equipment and knowledge to tackle tough stains and odors, giving your mattress the deep cleaning it needs.

Research and choose a reputable cleaning company

When choosing a professional mattress cleaning company, it's essential to do thorough research and select a reputable service provider. Look for companies with positive reviews, certifications, and experience in cleaning memory foam mattresses. Check their pricing, customer testimonials, and availability to ensure they meet your specific needs.

Follow their instructions for mattress preparation and scheduling

Once you have chosen a professional cleaning company, make sure to follow their instructions for mattress preparation and scheduling. They may require you to remove bedding, vacuum the mattress, or perform any other necessary steps before their arrival. Adhering to their guidelines will ensure a smooth and successful cleaning experience.

Alternative Methods and Products

Try using hydrogen peroxide or enzyme-based cleaners

In addition to the vinegar and baking soda methods mentioned earlier, you can also try using hydrogen peroxide or enzyme-based cleaners to tackle urine stains on a memory foam mattress. Hydrogen peroxide is a powerful stain remover, while enzyme-based cleaners break down organic matter and eliminate odors effectively. Always test these products on a small, inconspicuous area of the mattress first to ensure they do not cause discoloration or damage.

Test any new cleaning product on a small, inconspicuous area of the mattress first

Before using any new cleaning product or method on your memory foam mattress, it's crucial to test it on a small, inconspicuous area first. This will help you determine if the product is safe for your mattress and if it effectively removes urine stains and odors. Apply a small amount of the product and follow the manufacturer's instructions. If no adverse effects occur, you can proceed with treating the entire stained area.

Is It Possible to Cut a Memory Foam Mattress?

Cutting memory foam mattresses is possible, but it requires careful consideration. While it's feasible to trim the mattress to adjust its size or shape, doing so may affect its structural integrity and comfort. Seek professional assistance or follow manufacturer guidelines to ensure a successful and safe alteration.


Regularly maintaining your memory foam mattress is crucial to prevent urine stains and odor buildup. Accidents happen, but with prompt action and the appropriate cleaning steps, you can effectively remove urine from your mattress and restore its freshness. Remember to assess the damage, remove excess urine, neutralize the odor, clean the stain, dry the mattress thoroughly, deodorize it, and take preventive measures to avoid future accidents. If needed, consider professional cleaning services or alternative methods and products. By following these steps, you can ensure that your memory foam mattress remains clean, fresh, and free from any lingering urine odors.
