How To Take Urine Out Of a Mattress: Step‑By‑Step Guide and FAQ

If you’re searching for “How To Take Urine Out Of a Mattress”, you’re likely dealing with a fresh accident or an old stain and want to know what actually works. This guide walks you through simple, at‑home methods to remove urine, reduce odor, and protect your mattress without harsh products or complicated steps.

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

The most reliable method combines blotting, gentle cleaning, and odor-neutralizing ingredients.

Step‑by‑step for fresh urine stains

  1. Act quickly and blot, don’t rub

    • Remove all bedding.
    • Use clean, absorbent towels or paper towels to press firmly into the wet area.
    • Keep blotting until no more moisture lifts out. Avoid rubbing, which can push urine deeper into the mattress.
  2. Apply a mild cleaning solution

    • Mix a simple solution:
      • ½ cup cool water
      • ½ cup white vinegar
    • Lightly spray or dab the solution onto the stained area. The vinegar helps break down urine residues and reduce odor.
    • Let it sit for about 10–15 minutes, then blot again with dry towels.
  3. Use baking soda to absorb moisture and odor

    • Sprinkle a generous layer of baking soda over the treated area.
    • Gently work it in with your fingers or a soft brush.
    • Leave it on for at least 8 hours, or ideally overnight, to absorb remaining moisture and smell.
  4. Vacuum thoroughly

    • Once the baking soda is completely dry, vacuum it up using an upholstery attachment.
    • Repeat a light baking soda application if any odor lingers.

How Do You Get Old or Dried Urine Out of a Mattress?

Older stains are more stubborn because they’ve had time to set into the foam and fabrics.

Treating dried urine stains

  1. Re-wet the area slightly

    • Lightly spray the stain with the vinegar and water mix so the area is damp, not soaking.
    • This helps loosen dried residues.
  2. Let it sit longer

    • Allow 15–30 minutes of contact time.
    • Blot out as much liquid as possible.
  3. Add baking soda and wait

    • Cover the area with baking soda and leave it for several hours or overnight.
    • Vacuum thoroughly.
  4. Repeat if needed

    • Older stains sometimes need 2–3 rounds of treatment.
    • If the stain is still visible but lighter, another cycle may improve the result.

Will Urine Smell Stay in My Mattress?

Urine can leave a lingering odor if it isn’t fully removed. The smell often comes from residues left behind as the liquid dries.

To reduce odor effectively:

  • Use enough solution to reach the full depth of the stain, but do not soak the entire mattress.
  • Allow complete drying time with good airflow or a fan.
  • Use baking soda generously, as it helps absorb odor over time.

If an odor remains after cleaning, a second or third treatment with vinegar solution and baking soda is a common next step.

How To Take Urine Out Of a Mattress Without Damaging It

Mattresses are sensitive to excess moisture and harsh chemicals. To clean safely:

  • Avoid soaking: Too much liquid can travel deep into the mattress and be slow to dry.
  • Use mild ingredients: Water, white vinegar, and baking soda are generally gentle on most mattress materials.
  • Skip strong bleaches or solvents: These can discolor fabrics or degrade foams.
  • Help it dry: Open windows, use fans, or place the mattress in a well‑ventilated area so it dries faster.

Can I Use Enzyme Cleaners for Urine on a Mattress?

Many people use enzyme‑based cleaners made for biological stains like urine. These cleaners are designed to break down organic residues and help reduce odor.

If you choose to use one:

  • Test on a small, hidden area first to check for discoloration.
  • Follow the label directions carefully, especially for dwell time and drying.
  • Still finish with baking soda if any mild odor remains.

How Long Does It Take a Mattress To Dry After Cleaning Urine?

Drying time depends on room temperature, airflow, and how much liquid was used:

  • Light treatments can dry in several hours.
  • Deeper cleanings may take a full day or longer.

To speed drying:

  • Place the mattress in a well‑ventilated room.
  • Use fans or an open window.
  • Avoid covering the cleaned area with bedding until it is completely dry to help prevent musty smells.

How Can I Prevent Future Urine Stains on a Mattress?

Once you’ve learned how to take urine out of a mattress, it makes sense to protect the bed going forward:

  • Use a waterproof mattress protector to create a barrier between spills and the mattress core.
  • Choose washable mattress pads or covers that are easy to remove and clean.
  • Address any future accidents as soon as possible for the easiest cleanup.
