How To Get Urine Out Of a Mattress: Simple Steps That Actually Work

If you’re searching for “How To Get Urine Out Of a Mattress,” you’re likely dealing with a fresh accident, a lingering smell, or an old yellow stain. This guide walks you through practical, at-home methods to clean urine from a mattress, reduce odor, and protect your bed for the future.

What’s the Best Way To Get Urine Out Of a Mattress Fast?

The best approach is to act quickly, blot (not scrub), and use simple household cleaners that break down the urine and help lift it from the mattress.

Step-by-step: Fresh urine stains

  1. Strip the bed immediately
    Remove sheets, mattress protector, and bedding so the urine doesn’t spread deeper.

  2. Blot, don’t rub
    Use clean, dry towels or paper towels to gently press and absorb as much liquid as possible.
    Rubbing can push urine deeper into the foam or padding.

  3. Apply a mild cleaning solution
    A common DIY cleaner is a mix of:

    • Cool water
    • A small amount of gentle liquid detergent or mild dish soap

    Lightly spray or dab this onto the stained area. Do not soak the mattress; too much liquid can be hard to dry and may cause odors.

  4. Blot again
    Use fresh towels to lift the cleaning solution and remaining urine from the mattress surface.

  5. Deodorize with baking soda
    Sprinkle a generous layer of baking soda over the damp area. Baking soda helps absorb moisture and smells.

  6. Let it dry thoroughly
    Leave the baking soda on the mattress for several hours or overnight if possible. Good airflow and, if available, a fan can speed up drying.

  7. Vacuum the baking soda
    Once completely dry, vacuum the area to remove all baking soda. Check for any lingering smell or staining and repeat if needed.

How Do I Remove Dried or Old Urine Stains From a Mattress?

Dried urine can leave yellow stains and stubborn odors. The process is similar but may take more than one round of cleaning.

Extra steps for set-in stains

  • Use your cleaning solution more than once, allowing it to sit for 10–15 minutes each time before blotting.
  • Gently work the cleaner into the fabric with a soft cloth or sponge (still avoid harsh scrubbing).
  • After blotting, use baking soda again to help lift the odor over time.

Some people also use specialized enzyme-based cleaners designed for organic stains. These are commonly used for pet messes and are made to help break down urine components. Always spot test a small, hidden area first to make sure it doesn’t discolor or damage your mattress fabric.

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

Even after the stain is lighter, odor can linger in the deeper layers. To help with the smell:

  • Repeat baking soda treatments
    Leaving baking soda on the mattress more than once can gradually reduce odors.

  • Allow maximum airflow
    If possible, stand the mattress on its side in a well-ventilated room.
    Good air circulation helps moisture and smells dissipate over time.

  • Be patient
    Odors from deeper layers may fade slowly. It is common to need multiple cleaning sessions, especially after larger accidents.

Is It Safe To Use Vinegar, Hydrogen Peroxide, or Other Home Remedies?

Many people wonder if common household liquids will help when they search How To Get Urine Out Of a Mattress.

  • White vinegar
    Some use diluted vinegar for odor control. It has a strong smell at first and may not be suitable for all mattress fabrics. Always test a small area first.

  • Hydrogen peroxide
    It may help lighten stains, but it can also bleach or discolor some materials. Use caution:

    • Test an inconspicuous spot
    • Use a low concentration
    • Avoid over-saturating the mattress
  • Strong chemicals or steam
    Harsh cleaners and hot steam can sometimes damage mattress materials or affect comfort layers. Most mattress owners prefer mild, fabric-safe solutions instead.

How Do I Prevent Future Urine Stains on a Mattress?

Once you’ve gone through the effort to get urine out of a mattress, prevention becomes a priority.

  • Use a waterproof mattress protector
    A protector creates a barrier between spills and the mattress interior.
  • Choose washable layers
    Mattress pads and toppers that can be machine washed make cleanup easier.
  • Clean accidents promptly
    The faster you blot and treat a fresh spill, the less chance it has to soak deep and create permanent odors.
