How to clean tough pet or dog urine stains out of a memory foam mattress

Other than human urine, pet urine can be more smelly and bad to remove. It is because animal urine is more concentrated due to different substances present. For your reference, human urine contains 95% water whereas pet urine is more concentrated comparatively.

Another most important reason to treat pet urine immediately is that pets have a habit of marking their territories for repeated actions. Thus, your pet may repeat the same habit of peeing after seeing the stains or feeling the smell of its urine in the mattress.

Although most steps are similar, few things need to be added. Check out these tweaks that are simple but effective to follow for pet pee stains on memory foam mattresses.

5 Steps to clean Pet urine from a memory foam mattress

1. Apply baking soda

Unlike other methods where you dilute the baking soda, sprinkle the baking soda directly on the pee stain. Baking soda powder helps to absorb wet moisture.

The color of the baking soda turns darker as it continues to absorb the urine and the moisture from the mattress.

2. Repeat Process

Pick up the soiled and dried baking soda powder from the mattress. Add more ounces of fresh baking soda powder and let it soak the remaining urine too from the mattress.

You will need to repeat these steps until the color of the baking soda remains white on the soiled surface.

3. Cleaning the mattress

Once the urine is completely cleaned by baking soda, clean the mattress as you would do in case of human urine i.e. vacuum the powder and clean the mattress by washing it in the washing machine with a good detergent.

4. Enzyme method

You may also use enzyme cleaner instead of laundry detergents to clean the mattress. Enzyme cleaners are stronger to clean tough elements present in ammonia, fatty acids, animal urine, and more. You may find enzyme cleaners at the pet store or online.

5. Pet Repellent

Despite the mattress being cleaned, there could be some smell or traces that would allure your pet to pee again on the same spot. It could be due to urine’s chemical footprints that are sometimes left behind.

After all the steps of cleaning are completed, you need to use a pet-friendly repellent so that your pet doesn’t trace the pee area to repeat the habit.

*Tip: Avoid toxic products or products containing chemicals. The place where your pet, kid sits, or plays around cannot have strong chemicals. You must avoid using cleaning agents that contain hydrogen peroxide or similar bleaching agents that could be hazardous to babies and animals.

5 Steps to clean urine from a memory foam mattress topper

1. Vacuum often

Regularly vacuuming the mattress topper helps to get rid of the smell and dirt caused by urine. Vacuuming also takes away the micro-organisms released from the urine.

You need to place the mattress topper on a flat surface and clean all the spots and corners using your vacuum cleaner.

Use a strong handheld vacuum cleaner with a soft brush attachment to pick all the dust. Handheld vacuum cleaners help to clean the mattress nicely in circular motions.  

For dry and tough urine stains, use a wet-dry vacuum cleaner and let the topper dry for some hours under the fan or sun to use it again.

2. Use a detergent

As soon as the vacuum process is completed, spray some detergent to get rid of any odor or smell of urine. Pour a small amount of detergent in lukewarm water and mix it well.

Shift the liquid in the spray bottle to store the detergent water and spray on the mattress topper gently. Do not wet or soak the mattress topper too much with the liquid.

Bloat the excess water and moisture, clean with a dry cloth, and let the topper dry naturally. This will soak up all the urine and remove the bad smell from the topper.

3. Patch cleaning

Patch or spot cleaning involves cleaning the specific area of the topper that has become affected due to urine. Mix white or clear vinegar in water.

Dip a dry clean towel or cloth in the solution and rub the stains gently from the topper with the solution. Rub gently in a circular motion.

After the stains seem fading away, clean with just plain water gently in circular motion. If you still notice stains, then you can follow the detergent method again.

Don’t forget to be gentle on the foam while rubbing else you may risk its quality.

*Tip: As an alternative, you may also add baking soda to water, dissolve it until you see a milky white solution, and dip a cloth to follow the same process of cleaning as explained in step 3.

4. Odor removal

Urine stains, vomit stains, and cigarette smoke can sometimes create a foul smell on the mattress topper making it difficult to live with it.

After the spray cleaning, you need to sprinkle baking soda on the area and leave it overnight for the best results.

You may also sprinkle baking soda overnight before the vacuum process as well for best results. Other than baking soda, you have good cleaning agents that contain citrus products.

5. Topper cover

Protecting the topper with a cover is essential. After you have finished cleaning the mattress topper cover it with a waterproof and leak-proof cover. It also helps to protect the mattress and the topper from dust mites and spillage.

Another benefit of using topper covers after cleaning is that you can throw the cover for several machine washes keeping the topper in perfect shape and state as it was while cleaning.
