Accidents happen, and when they involve urine on a mattress, knowing what to use to get urine out of a mattress is the first step to saving your bed. This guide gives you clear, effective methods for both fresh and old stains, using common household items.
What To Use To Get Urine Out Of A Mattress
The best solutions are often already in your home. You don’t need harsh chemicals. For fresh urine, the goal is to absorb and neutralize. For set-in stains, you need to break down the uric acid crystals. Here’s a quick list of what works:
- White Vinegar: A mild acid that neutralizes ammonia and breaks down urine salts.
- Baking Soda: A fantastic odor absorber and mild cleaner.
- Hydrogen Peroxide (3%): A bleaching agent that disinfects and helps remove stains.
- Liquid Dish Soap: A gentle surfactant that lifts stains without damaging fabrics.
- Enzymatic Cleaner: Specially designed to “eat” organic matter like urine proteins.
- Cold Water: Always use cold, as heat sets protein stains.
Why Urine is So Tough to Remove
Urine isn’t just water. It contains urea, uric acid, and other compounds. When urine dries, the uric acid forms crystals that bond tightly to mattress fibers. Water alone can’t break these bonds. In fact, it can make the smell worse by re-activating the crystals. You need a solution that dissolves these crystals and neutralizes odors at the source.
Immediate Action for a Fresh Accident
Speed is your best friend here. The faster you act, the better your chances of complete removal.
- Blot, Don’t Rub: Use clean, dry towels or paper towels. Press down firmly to absorb as much liquid as possible. Rubbing pushes the urine deeper.
- Rinse with Cold Water: Lightly dampen the area with cold water from a spray bottle. Then, blot again to dilute and remove more residue.
- Apply a Vinegar Solution: Mix equal parts white vinegar and cold water in a spray bottle. Generously spray the area. The vinegar will start neutralizing the ammonia smell.
- Blot Again: After letting it sit for 5-10 minutes, blot up the vinegar solution.
- Deodorize with Baking Soda: Cover the damp spot liberally with baking soda. Let it sit for several hours or overnight to absorb moisture and odors.
- Vacuum Thoroughly: Use an upholstery attachment to vacuum up all the dried baking soda.
Tackling Old or Set-In Stains and Odors
For stains that have been there a while, you need a stronger approach. This method combines cleaning power with stain lifting.
- Vacuum the Area: Remove any surface dust or debris.
- Make a Cleaning Paste: In a bowl, mix baking soda, a small amount of hydrogen peroxide (3%), and a drop of liquid dish soap to form a thick paste.
- Apply the Paste: Spread the paste over the stained area. You don’t need to scrub it in hard; just let it cover the stain.
- Let it Dry Completely: This is crucial. Allow the paste to dry fully, which may take up to 24 hours. As it dries, it pulls stains and odors out.
- Vacuum Again: Once bone dry, vacuum the area completely.
- Final Vinegar Spray: Lightly mist the area with your vinegar-water solution to ensure odor neutralization. Let it air dry.
When to Use an Enzymatic Cleaner
If the smell persists after cleaning, it means uric acid crystals remain. An enzymatic cleaner is your best option. These contain live bacteria that digest the urine proteins. Simply follow the instructions on the bottle, which usually involve soaking the area and letting it air dry. Patience is key, as the enzymes need time to work.
Essential Tools and Supplies You’ll Need
- Clean white cloths or paper towels
- Spray bottles
- White vinegar
- Baking soda
- Hydrogen peroxide (3%)
- Liquid dish soap
- A bowl for mixing
- A vacuum with an upholstery attachment
- A fan (to speed drying)
Step-by-Step Deep Cleaning Method
For a very stubborn stain, this detailed process combines all the effective elements.
- Preparation: Strip all bedding and wash it. Open windows for ventilation.
- Initial Blot: Even if the stain is old, lightly dampen it with cold water and blot to loosen crystals.
- Vinegar Soak: Spray the vinegar solution heavily onto the stain. Allow it to soak for 15 minutes.
- Baking Soda Application: While the area is still damp, cover it with a thick layer of baking soda.
- Peroxide Boost: In a spray bottle, mix 1 part hydrogen peroxide to 2 parts cold water. Lightly mist the baking soda. You’ll see it fizz—this is working.
- Dry Thoroughly: Let the mattress dry completely. Using a fan can cut drying time in half.
- Final Vacuum: Vacuum the entire mattress surface to remove all residue.
Common Mistakes to Avoid
- Using Heat: Never use a steam cleaner or hot water on a urine stain. Heat permanently sets the protein and the smell.
- Ammonia-Based Cleaners: Ammonia is a component of urine. Using it can intensify the odor, making the problem worse.
- Soaking the Mattress: Too much moisture can lead to mold and mildew inside the mattress. Always use minimal liquid and ensure rapid drying.
- Covering the Smell: Spraying perfumes or aerosol air fresheners only masks the odor temporarily. You must neutralize it.
Protecting Your Mattress After Cleaning
Once your mattress is clean and dry, protect it to prevent future issues. A high-quality, waterproof mattress protector is a must. Look for one that is breathable and doesn’t make noise. It will guard against urine, sweat, and spills, extending your mattress’s life significantly. Regularly airing out your mattress by stripping the bedding for a few hours can also help keep it fresh.
FAQ Section
What gets urine out of a mattress the best?
A combination of white vinegar and baking soda is often the most effective home remedy. For persistent biological odors, a commercial enzymatic cleaner is the best solution as it breaks down the urine at a molecular level.
Can you use baking soda and vinegar together on a mattress?
Yes, but apply them in sequence, not as a pre-mixed solution. The vinegar acts as a neutralizer first. Then, baking soda is applied to absorb odors and moisture. Sometimes they are combined in a paste with peroxide for set-in stains.
How do you get old urine stains out of a mattress?
Old stains require a paste of baking soda, hydrogen peroxide, and dish soap. Apply it, let it dry completely to draw out the stain, and then vacuum. An enzymatic cleaner is also highly recommended for old, smelly stains.
Does hydrogen peroxide ruin mattresses?
3% hydrogen peroxide is generally safe for most mattresses, but it has bleaching properties. Always test it on a small, inconspicuous area first (like a corner or seam) to check for colorfastness before applying it to the stain.
Why does my mattress still smell like urine after cleaning?
This usually means uric acid crystals are still deep in the mattress layers. The cleaning may have missed them. Re-treat the area with an enzymatic cleaner, ensuring it soaks deep into the spot, and allow plenty of time for it to work before drying.
How can I make my mattress dry faster after cleaning?
Use fans to circulate air in the room. Open windows for a cross-breeze. If possible, stand the mattress on its side (if the manufacturer allows). Avoid using direct heat like a hair dryer, as it can damage mattress materials.
Final Thoughts
Dealing with a urine stain on your mattress can feel overwhelming, but with the right tools and patience, you can restore it. Remember the golden rules: act fast with fresh stains, always use cold water, and never skip the drying step. By understanding what to use to get urine out of a mattress—like vinegar, baking soda, and enzymes—you can tackle the problem effectively. A protected mattress is a happier mattress, so consider investing in a good cover once its clean and fresh again.
