What’s the best way to remove fresh pee from a mattress?

Fresh accidents are usually easier to handle. The key is to act quickly and avoid pushing the liquid deeper into the mattress.

Step-by-step for fresh urine:

  1. Blot, don’t rub

    • Use clean, dry towels or paper towels.
    • Gently press to soak up as much liquid as possible.
    • Avoid scrubbing, which can spread the stain and push it deeper.

  2. Apply a gentle cleaning solution

    • Mix a simple solution:
      • About 1 part mild dish soap to 4–5 parts cool water, or
      • A small amount of laundry detergent in cool water.
    • Lightly dab the solution onto the stained area with a clean cloth.
    • Continue to blot; don’t oversaturate the mattress.

  3. Rinse lightly with clean water

    • Dampen a fresh cloth with cool water.
    • Blot the area to lift away soap and residue.
    • Again, avoid soaking the mattress.

  4. Deodorize with baking soda

    • Sprinkle a generous layer of dry baking soda over the damp area.
    • Leave it for several hours, ideally overnight, to absorb moisture and odours.

  5. Vacuum thoroughly

    • Once the baking soda is completely dry, vacuum it up using the upholstery attachment.
    • Let the mattress air out until it feels fully dry before putting bedding back on.

For older or dried stains:

  1. Lightly rehydrate the area

    • Mix cool water with a small amount of mild detergent.
    • Lightly mist or dab onto the stained area; avoid soaking.

  2. Use a vinegar-based solution

    • In a spray bottle, mix:
      • About equal parts white vinegar and cool water, plus
      • A small amount of mild dish soap if desired.
    • Spray or dab onto the stain until it’s damp, not dripping.
    • Let it sit for 10–15 minutes to help loosen the residue and reduce odours.

  3. Blot and absorb

    • Blot thoroughly with clean, dry towels to remove as much moisture as possible.

  4. Add baking soda and wait

    • Cover the area with a thick layer of baking soda.
    • Leave it on for at least several hours, preferably overnight.

  5. Vacuum and repeat if needed

    • Vacuum up the dried baking soda.
    • If the stain or smell is still noticeable, you can repeat the process.

How do I get rid of lingering urine smell in a mattress?

If you’ve already cleaned the stain but notice a lingering odour, focus on odour absorption and ventilation.

  • Use extra baking soda: Sprinkle a light layer over the area and leave it for 24 hours if possible.
  • Air out the mattress:
    • Open windows to improve airflow.
    • If safe and practical, place the mattress in a well-ventilated, shaded area to air out.
  • Avoid strong fragrances: Sprays that only mask odours often fade quickly and may mix with the smell instead of solving it.

If smells persist after several attempts, it may be because urine soaked deeply into the mattress layers, which can be harder to fully remove.

Is it safe to use bleach or harsh chemicals on a mattress?
