Urine Stains on a Mattress

How do I remove urine from a mattress? I have a 2 year old sharing my bed, a pillow top mattress, and I tried to steam clean it. All it did was spread the stain everywhere. It doesn't smell. I tried Hydrogen Peroxide, baking soda and a pinch of detergent method and it all clumped up on the bottom of the spray bottle and wouldn't spray! Any help is welcomed!

I use Folex to treat old stains, you spray it on and rub it in. It works great for those body oil stains and any other fluid. My son's diaper leaked on mine, so I blotted then let baking soda absorb the rest. After I vacuumed it up (left it for at least 6 hours) I used the folex and direct sunlight. Sunlight is used as a natural whitener and disinfectant. Folex is at Walmart, EDIT: in the carpet cleaner section (bottom shelf) about $7, but is SO worth it! It doesn't have fumes, actually it is enzyme based and works great!

Then I would get a waterproof mattress cover if this is a common thing, and use Luvs or good store brand at night! (06/06/2007)

Steam cleaning ( hot) will set in most stains.
You want to use a cold water solution. (06/07/2007)

Denver mattress stores sell a kit for mattress', and trust me, those are worth every penny. My husband sweats and smells metallic. He drenches sheets through the mattress pad at night, so I use the urine remover spray and it works! I wash sheets with white distilled vinegar for fresh bedding in HOT water. (06/07/2007)

I would suggest buying one of those small steam cleaners and getting the urine stain cleaner that goes in them. Hopefully that will get rid of it. (06/08/2007)

I don't know how to remove the stains but I can help you prevent more. Buy one of the allergy covers for the mattress. They make ones that are vinyl. You can't tell that you're sleeping on it as it's soft but it keeps the mattress clean. (06/08/2007)

Miracle! My daughter made a huge urine stain on our pillow top mattress. Unfortunately it set in and the stain looked horrible! I put "Resolve Dual Action" carpet cleaner on it and rubbed it in well. Not only did it take the stain out, but it made is smell great! (06/28/2007)

I used white vinegar starting from the outside to the inside while stain was still wet. I used a regular towel to blot and then sprinkled with baking soda and vacuumed the pillow top the next day. It worked great and no smells. (07/20/2007)

My daughter had an accident on my very expensive pillow top mattress. I found this site and figured I would try the hydrogen peroxide method. It worked great! You just need to make sure you use it right away before it starts foaming.

Thanks! (10/24/2007)

Cats and dogs, especially those not neutered, have a tendency to "mark their territory" and it is essential to the homeowner to remove all traces of the urine to keep the pet from returning to the same spot and leaving urine stains again.

Many products on the market today will clean the initial stain. The biggest issue with cat urine is that the odor inevitably will return unless the stain is treated properly to begin with. Animal urine is composed of three elements. These are urea, which the sticky tacky part, urochrome, which is the pigment or color element, and the uric acid crystals and salts. The first two elements can be easily removed. It is the uric acid crystals that cause the returning odor on hot sticky days, or when it rains. Uric acid contains non-soluble salt crystals, which tightly bond to the surface. Removing these uric acid crystals effectively removes the odor from your home.

One of the most highly recommended products for the removal of urine stains is Urine Off. This product is enzyme based, which attacks and destroys the uric acid crystals. Other veterinarian recommended products are Atmosklear Odorless Odor Eliminator, a spray product that Neutralizes the uric acid crystals. Also veterinarian recommended is Feliway. Feliway comes with two products - a diffuser that is plugged into an outlet that controls odor over a 500-650 square foot area, and a spray that is used on areas of the home that the cat is marking.

A solution using common household items is made by mixing one part water to three parts white vinegar. Place something heavy, such as a laminated book, over the stain. This stops the solution from simply evaporating into the air, and allows it to work. Do not blot. Allow the solution to dry. Step two involves mixing a solution of three parts water to one part vinegar, and repeating the process. When completely dried, use 1 teaspoon liquid detergent to one cup of water, and thoroughly cleanse the area, blotting it dry. The vinegar smell will dissipate in a few days.

Caring for and cleaning up after your pet does not need to be a daunting task. Always remember, though, that a cat or dog has a sense of smell that is 10 times greater than humans. The pet will return to the same spot if the odor is not eliminated. Doing the job right in the first place will eliminate a lot of headaches, and make your co-existence with your pets more enjoyable.

The Hydrogen Peroxide method works the best. It takes the stain and the smell out in seconds! Thanks for the information! (02/04/2008)

My toddler peed on a sofa, hitting the leaning part of it as well. I first removed the cushion out of its cover; I have one of those super soft faux suede sofas; I found out it's no problem washing it in a laundry machine. I sprayed the stain on the cushion cover with Shout and washed with a regular detergent on a gentle cycle then air dried.

The stain on the leaning part of the sofa I first blotted out with paper towel as much as possible, than I sprayed it with 3 to 1 solution of water and vinegar. I let it soak, blotted out, sprayed again, then sprinkled with baking soda and vacuumed the next day. Sofa is stain and odor free!

I love baking soda, find out more about it, it's brilliant for so many things, eliminates odors and lightens the area without the worry of bleached spot by peroxide, which I was scared to use on my darker toned sofa.
Thanks for all the posts, it helped a lot!

We have dogs and accidents happen. I use a product named Simple Solutions. It can be purchased at PetSmart. I use it in my steam cleaner to clean upholstery, mattresses, washing dog beds, carpet, etc. It works great at removing odors and stains of all kinds. I had a professional carpet cleaner tell me if he couldn't get the stain out, nothing could. He was WRONG! He couldn't get the stain out but I cleaned it with Simple Solutions and it came right out. You can purchase Simple Solutions by the spray bottle or the the gallon. (06/09/2008)

Carpet fresh on the stain. Rub some into the fabric, then add extra put a lightly blowing fan toward it for 3-4 hours, vacuum and then stand the mattress up. Now let the fan blow the carpet fresh through to kill the smell. Once the odor is gone you can cover the mattress with a mattress cover. That is good for the light weight mattresses.

For the thick mattresses, you may need to pour vinegar though the stain. You want to get rid of the odor, then you can let it dry outside or get as much water out as possible. Then stand it up and let fans blow on it for several hours until completely dry. Then you can cover it with a mattress cover. Good luck. (06/22/2008)

I used the peroxide method below on my 3-yr old sons mattress and it worked like a charm. No smell, no stain. Thank you! (07/09/2008)

I'm pretty sure that humidity brought the urine that was beneath back up to the surface, well, that & the pressure of laying on it. What you need to do is buy yourself a bottle of plain old hydrogen peroxide & pour that down into the mattress. The oxygen in the peroxide fizzes out the stain & it will get right down into the stain. Then obviously you'll need to let the mattress air out until it dries totally before putting any plastic on it again. But before the plastic, there's one more thing I would do first & that's buy a spray bottle of "OUT!" at Walmart for $4.79 (or any brand of "enzyme" pet urine cleaner) & spray this on to (& maybe down into) the stain. Do not use a blow dryer because you need to keep the enzyme cleaner wet for it to work. The enzymes & good bacteria in this product actually "eats" the urine. It's pretty amazing stuff!

Cyinda, Thanks so much for taking the time to respond to my question. Your suggestions sound great. I will try them. Geri (09/16/2008)

Just to add to previous feedback. Good advice on the enzyme product. That is valid. However, sometimes the stain will return and that is due to what is called "wicking". Although the bacteria and such has been destroyed, the unsightly stain spot has not. To avoid this in most cases, treat the spot as usual and then turn the mattress over (suspended) over the treated area so that when it dries, it will "wick" back up into the mattress, and you won't have to see the stain any longer. A trick I learned while involved in carpet cleaning and working on upholstery. It works. It will always "wick" up so use that to your advantage. (09/17/2008)

Mike, Thanks for the information. Unfortunately, my pillow top mattress is way too heavy to lift. Please clarify "suspended", like leaning against a wall? If wicking is the only way to get rid of the stains, I'll get some friends to help me lift it. (09/18/2008)

I have a 2yr old and he had several accidents on our euro top mattress. When it is fresh we used damp cloth to wipe the area and dried it with hair dryer. But it left a stain after few days. We used "shout" and baking soda mixed in water and it cleaned the stains and the mattress looks new once again! (09/22/2008)

Have had some mattress issues. Might I mention borax, in the laundry section. Great for stained mattress and urine smell. I had something very similar happen to me, the borax worked great. (09/24/2008)

I have a dog that would get mad at me for working too much and not paying enough attention to her, that she would pee on my bed. I use baking soda, perfume and water. Shake it frequently and just spray a little on the spot and scrub. Comes right out! (10/19/2008)

THANK YOU, THANK YOU. I followed the "recipe" from 4/2006 and it worked. Peroxide, baking soda & a pinch of detergent. (10/22/2008)

It works, but I had to do it twice to get out the stain.

Here's the formula again:

Mix this & spray on. Must use within 20 minutes & do not attempt to store the remainder in a closed bottle. It works by producing bi-products that are only active for that time period anyway. Stored, it leaks or foams out of the bottle!
Mix: about 8 oz. Hydrogen Peroxide (brown bottle in 1st aid aisle) & 3 tablespoons baking soda (small box in baking aisle), & a drop of liquid hand dish washing soap. Mix well & spray onto stain, within 5 minutes stain should be gone. If the baking soda leaves a white powder, you can vacuum it off, or wipe w/ damp rag, but this usually is not a problem unless you add too much baking soda.

I had very bad, old stains on my pillow top from my daughter's "accidents". Didn't think anything would ever get them out. I did the hydrogen peroxide, baking soda and liquid soap mix, but it clogged the spray bottle and wouldn't spray anymore. Desperate, I just poured it right onto the stains. After 15 minutes, nothing happened, and I was afraid this was just "too good to be true". But alas, I let it dry overnight, and the next morning the stains were gone. It's a miracle! (11/09/2008)
