How to Clean a Mattress: Urine Stains

Murphy’s Law states whatever can go wrong will go wrong, and that most certainly applies to “accidents” on the brand new mattress. From an accident caused by your little one to the family pet draining themselves on that brand new duvet, figuring out how to clean urine from a mattress as well as how to get the urine smell out of a mattress can be quite the hassle.

While cleaning mattress stains is no easy task, learning how to get out mattress stains can keep your mattress fresh for years to come. However, when you’re dealing with stains beyond the norm (e.g. urine, blood, other bodily fluids), removing mattress stains is taken to a whole new level.

So, if you’ve googled: “How to get out mattress stain,” we are here to help. To take the mystery out of how to clean mattress stains, here are a few tips for cleaning urine from your mattress without completely losing your mind. (Before you clean your mattress yourself with these handy tips, be sure to check the factory warranty to ensure your cleaning efforts don’t void the warranty.)

How to Clean Mattress Stains

1. The Fresher the Stain, the Better the Clean Up

If you are (un)fortunate enough to catch the urine stain on your mattress as soon as it happens, your first move should be to blot up as much of it as you can using a paper towel or a sponge. If you own a wet/dry vacuum, use this to help soak up the urine from your mattress. Sprinkle baking soda on the affected area to clean up any remaining moisture.

2. Laundry Detergent: The Magic Cleaning Elixir for Urine Stains

Laundry detergent is your best friend when it comes to removing the smell of urine from your mattress. Once you’ve soaked all the fresh urine from the mattress, or if the stain was too old to be able to soak up urine, mix a couple of teaspoons of laundry detergent in a cup of warm water and pour (or spray of you have access to an empty spray bottle) onto the affected areas. Alternatively, you can also use a solution of one-part warm water and one-part vinegar if you can stand the smell.

3. Blotting Your Magic Elixir Over the Urine Stain

Once you’ve mixed up your magic cleaning solution and applied it to the part of your mattress where the urine is located, repeat the blotting process discussed earlier. Carefully blotting is important as it will remove any residual urine and prevent mold. Be sure and get the urine-affected area of the mattress as dry as possible after applying your cleaning solution.

4. Remove the Moisture and Urine Smell with Baking Soda

After you’ve dried up all the remaining moisture from the spot of the urine, sprinkle baking soda over the entire mattress. This will help to prevent the smell of the urine from seeping into any other parts of the mattress. The mattress needs time to completely dry out (18-24 hours), so you will have to make other sleeping arrangements for the night. After this time period has passed use a vacuum to remove all the baking soda and then prop up the mattress either outside or in a well-ventilated area to allow air to circulate and sift the last of the odor from the mattress.

5. Consult an Expert

If you’ve followed all the above steps and are still smelling urine on the mattress, you may need to reach out to a professional cleaning service to get their opinion of the damage. Professional cleaners can provide you with a proper assessment and give you the best recommendation to ensure you or your family member is sleeping on a clean bed.

However, if you find yourself in a predicament of having a soiled mattress or your bed is over eight years old, then it may be time to take a trip to your nearest Mattress Firm to upgrade your sleep space.

  1. Any tips on removing feces stains that have been in the mattress for over a year? I just don’t know how to get them out. I just ended up buying a nice cover for it. I really would like to get this stain out.

    • You can, but it won’t do much good in the long run. Only for a day or so. My nephew’s cat urinated on his mattress last week
      I walked him through my home remedy, which turns out to be almost exactly the same method given in this article. The only difference we used, is Dawn dish soap in place of laundry detergent. The strength of the dish soap will remove the odor with more certainty than detergent- if anything will. However, the urine on the featherbed was removed quite well by putting it right into the washer with Oxyclean spot cleaner for. It’s really the reaction of vinegar & baking soda that holds the key. The leeching quality of the baking soda and the acidity of the vinegar remove the odor. If you want to spray something long after the fact to mask the odor – I would mix 3 parts water to
      1 part vinegar in a spray bottle. Spray & blot the area until the liquid you sprayed on has been transferred from the mattress to your clean, blotting towel, not pushed down on, or rubbed vigorously. That will only serve to grind it into the mattress. Then repeat the baking soda step. Pouring it over the damp spot. You can leave it there for hours. Then, after it has dried you can mix some water with 10-20 drops of your favorite essential oil. I love lavendar, however a citrus oil such as lemon or orange may do a better job. Spray that mixture on the area as often as need be. The most important part being that the cat cannot smell where he/ she urinated, or it will keep happening. Spray with a product called, “Cat-off.” Or another mixture of vinegar, water and hydrogen peroxide, (after testing to be certain that it doesn’t bleach your mattress!) Both will help with keeping the cat from making a repeat performance as well. It just doesn’t smell as nice as any homemade essential oil mixture. Good luck!

    My dog peed after having surgery. I read people’s comments about vinegar etc. But it hate the smell of vinegar. So I blotted, sprinkled baking soda, when the baking soda was yellow I vacuumed reapplied baking soda, did this 3 more times. Then I sprayed it with peroxide and water and it’s completely gone.

  3. the mattress pad got most on it. I blotted it and then mixed 2 parts warm water 1 part white vinegar just a drop of dawn det. then I blotted it again and covered the stain with baking soda which I’ll vacuum up later when it dry’s I’m going to put a fan on it and its a warm day. I’ll let you know how it turns out. It was from an elderly parent
