How To Get Pee Out Of Your Mattress: Simple Steps That Actually Work

If you’re searching for “How To Get Pee Out Of Your Mattress,” you’re probably dealing with a fresh accident or a dried stain and worried about odour, hygiene, and long‑term damage. This guide walks you through what to do right away, how to handle older stains, and how to reduce lingering smells—using common household ingredients.

What’s the First Thing I Should Do When Pee Gets on a Mattress?

Act quickly. Fresh urine is much easier to remove than dried stains.

  1. Strip the bed
    Remove sheets, mattress protector, and blankets so you can treat the mattress surface directly.

  2. Blot, don’t rub
    Use clean, dry towels or paper towels to press and absorb as much liquid as possible.

    • Avoid scrubbing, which can push urine deeper into the mattress.

  3. Keep the area as dry as you can
    Once you’ve blotted thoroughly, you’re ready to use a cleaning solution.

How To Get Pee Out Of Your Mattress (Fresh Stains)

For most fresh accidents, a simple mild-cleaner + baking soda method works well.

Step 1: Mix a gentle cleaning solution

You can use:

  • A small amount of mild liquid soap mixed with cool water, or
  • A water and white vinegar mix (about 1 part vinegar to 2 parts water) for odour control

Always test your solution on a small, hidden area first to make sure it doesn’t affect the fabric or colour.

Step 2: Lightly apply the solution

  • Put the solution in a spray bottle if possible.
  • Lightly mist the stained area—do not soak the mattress.
  • Let it sit for about 5–10 minutes.

Step 3: Blot again

  • Use clean, dry towels to blot the area.
  • Repeat light spraying and blotting if the stain is still noticeable, keeping moisture to a minimum.

Step 4: Use baking soda for odour and moisture

  • Sprinkle a generous layer of baking soda over the damp area.
  • Gently spread it so it covers slightly beyond the stain.
  • Leave it for at least a few hours, or overnight if possible, so it can absorb moisture and odours.

Step 5: Vacuum thoroughly

  • Once the baking soda is completely dry, vacuum it up slowly.
  • Check the mattress: if a light odour remains, you can repeat the baking soda step.

How Do I Remove Dried or Old Pee Stains?

Older stains can be more stubborn, but you can still improve them with patience and repetition.

Step 1: Rehydrate the stain (carefully)

  • Lightly spray a water + white vinegar mix on the stained area.
  • You’re trying to soften and lift the old residue, not soak the mattress.

Step 2: Let it sit, then blot

  • Allow it to sit for 10–15 minutes.
  • Blot firmly with towels to remove as much liquid as possible.

Step 3: Add baking soda

  • Cover the treated area with a thick layer of baking soda.
  • Leave it for several hours or overnight, then vacuum.

You may need to repeat this process a few times for older stains. While some very deep stains may not disappear completely, many people see a noticeable improvement in both colour and smell.

Is It Safe to Use Strong Chemicals on a Mattress?

Many people wonder if they should use strong cleaners when figuring out how to get pee out of your mattress.

  • Avoid harsh chemicals that may irritate skin or damage mattress materials.
  • Check your mattress care tag for any manufacturer cleaning guidelines.
  • When in doubt, mild solutions (like diluted soap or vinegar) are usually a safer starting point.

If you choose a specialized cleaner, test a small, hidden spot first and ensure the mattress can dry thoroughly afterward.

How Do I Get Rid of the Smell Completely?

Even after cleaning, a light odour can linger. To help with that:

  • Ventilate the room: Open windows, use fans, and allow fresh air to circulate.
  • Sunlight can help: If practical and safe for your mattress type, brief exposure to indirect sunlight may help reduce odours.
  • Repeat baking soda: Another round of baking soda left on the area for several hours can further neutralize smells.

Odours usually fade more as the mattress dries completely, so full drying time is important.

How Long Does It Take a Mattress to Dry After Cleaning?

Drying time depends on:

  • How much liquid was used
  • Room temperature and airflow
  • Mattress thickness and materials

In general, expect many hours for the mattress to dry fully—often overnight or longer. To speed drying:

  • Use fans aimed at the mattress surface
  • Increase ventilation
  • Avoid putting sheets back on until the area feels completely dry to the touch

Can I Protect My Mattress From Future Pee Accidents?

You can’t prevent every accident, but you can limit the damage:

  • Use a water-resistant mattress protector to keep liquids from soaking into the core.
  • Consider easily washable protective layers (like an extra sheet or pad) for children or pets.
  • Deal with spills promptly, following the same blot–clean–baking soda–dry routine.

✅ Quick Mattress Takeaways

Key points to understand about How To Get Pee Out Of Your Mattress:

  • Act fast: Blot fresh pee immediately to stop it soaking deeper.
  • Use gentle cleaners: Mild soap-and-water or diluted vinegar are common options; avoid over‑soaking.
  • Baking soda is your friend: It helps absorb both moisture and odours.
  • Old stains need patience: Rehydrate lightly, blot, and repeat baking soda treatments as needed.
  • Drying is critical: A fully dried mattress is less likely to develop persistent odours.
  • Protection helps: A mattress protector and quick cleanup make future accidents easier to handle.

With a calm, step‑by‑step approach, getting pee out of your mattress usually comes down to gentle cleaning, careful drying, and a bit of time.
