How To Get Rid Of Urine Stains In Mattress: Simple, Effective Steps

If you’re searching for “How To Get Rid Of Urine Stains In Mattress”, you’re likely dealing with a fresh accident, an older stain, or lingering odor that just won’t go away. This guide walks you through practical, home-friendly methods to clean urine from a mattress and reduce smells, without special equipment.

What Happens When Urine Gets on a Mattress?

Urine can soak below the surface of a mattress and:

  • Leave yellowish stains
  • Create a persistent odor
  • Attract bacteria and general buildup over time

Because mattresses are absorbent and not easily machine-washed, knowing how to get rid of urine stains in a mattress quickly and safely can help keep it cleaner and more comfortable.

How To Get Rid Of Urine Stains In Mattress: Step-by-Step

1. What Should I Do Right After a Fresh Urine Accident?

Act fast. The sooner you start, the easier it is to remove the stain and odor.

  1. Blot, don’t rub

    • Use clean, dry towels or paper towels.
    • Gently press to absorb as much liquid as possible.
    • Avoid scrubbing, which can push urine deeper into the mattress.

  2. Mix a gentle cleaning solution
    Common options include:

    • Cool water and a small amount of mild dish soap, or
    • A mix of white vinegar and water (often about equal parts)

  3. Lightly apply the solution

    • Use a spray bottle or a clean cloth.
    • Dampen the stained area; do not soak the mattress.
    • Let it sit briefly, then blot again with dry towels.

  4. Dry thoroughly

    • Use fans or open windows to speed drying.
    • If possible, prop the mattress up so air can circulate around it.

2. How Do I Remove Dried or Older Urine Stains?

Older stains may be more stubborn, but you can still improve both appearance and smell.

  1. Rehydrate the stain

    • Lightly spray or dab the area with a vinegar-and-water mix.
    • This can help loosen dried residue.

  2. Use baking soda to tackle odor

    • Sprinkle a generous layer of baking soda over the dampened area.
    • Gently work it in with your fingers or a soft brush.
    • Leave it for several hours, or overnight if possible.

  3. Vacuum the baking soda

    • Once completely dry, vacuum thoroughly.
    • This removes the baking soda along with much of the trapped odor.

Repeat the process if the stain or smell lingers, especially for older, deeper spots.

3. Can I Use Hydrogen Peroxide or Other Stronger Cleaners?

Some people turn to hydrogen peroxide-based solutions for tough stains. These can help lighten discoloration but may also:

  • Bleach or lighten mattress fabric
  • Affect certain materials or covers

If you choose to use it:

  • Spot-test first on a hidden area.
  • Apply sparingly, and avoid soaking the mattress.
  • Blot and dry thoroughly.

For delicate fabrics or special mattress materials, gentler methods (vinegar, mild soap, baking soda) are usually safer.

How Do I Get Rid of Urine Smell in a Mattress?

Even when the stain fades, odor can remain. When considering how to get rid of urine stains in mattress cleaning, odor control is just as important as looks.

Common odor-reduction steps:

  • Vinegar solution: Helps neutralize many urine smells.
  • Baking soda: Absorbs odors when left on the mattress for several hours or overnight.
  • Fresh air: Letting the mattress air out in a well-ventilated room can help reduce lingering smells over time.

Avoid heavy perfumes or strong air fresheners directly on the mattress, as they can mix with the odor rather than remove it.

How Can I Prevent Future Urine Stains?

While accidents happen, a few simple habits can make future cleanups easier:

  • Use a removable, washable mattress protector.
  • Clean up spills or accidents as soon as you notice them.
  • Allow the mattress to dry completely after any cleaning before re-covering it with sheets or bedding.

Is It Ever Too Late to Clean a Urine-Stained Mattress?

It may not be possible to make an older mattress look brand new again, but even set-in urine stains and odors can often be reduced with repeated gentle cleaning:

  • Work in layers: clean, blot, dry, then deodorize.
  • Be patient and allow full drying between attempts.
  • Focus on reducing odor and surface discoloration rather than perfection.
