How To Get Pee Stains Off Of a Mattress: Step‑By‑Step FAQ Guide

If you’re searching for how to get pee stains off of a mattress, you likely want something that works, doesn’t damage your bed, and helps with both stain and odor. This guide walks through the most common questions, from fresh accidents to old, set-in spots, using simple household ingredients.

What’s the best way to get fresh pee stains off of a mattress?

For fresh accidents, acting quickly makes the biggest difference.

Step‑by‑step for fresh pee stains:

  1. Blot, don’t rub

    • Use clean, dry towels or paper towels.
    • Press firmly to soak up as much liquid as possible.
    • Avoid scrubbing, which can push urine deeper into the mattress.

  2. Apply a mild cleaning solution

    • Mix a small amount of gentle liquid detergent with cool water.
    • Lightly dab or spray onto the stained area (do not soak the mattress).
    • Blot again with a clean cloth to lift out the stain.

  3. Use an enzyme-based cleaner (optional but helpful)

    • Enzymatic cleaners are commonly used on urine because they help break down odor-causing components.
    • Follow the label instructions and avoid oversaturating the mattress.
    • Blot away excess moisture after the recommended contact time.

  4. Deodorize with baking soda

    • Sprinkle a thin, even layer of baking soda over the damp area.
    • Let it sit for several hours, or until completely dry.
    • Vacuum thoroughly to remove the baking soda.

How do I remove dried or old pee stains from a mattress?

Older stains are more stubborn, but you can still improve or remove them with patience.

Method for dried pee stains

  1. Lightly re-dampen the area

    • Use a small amount of cool water in a spray bottle to soften the dried stain.
    • Do not soak; you want the surface just slightly damp.

  2. Use a vinegar and water solution

    • Mix equal parts white vinegar and water.
    • Lightly spray or dab on the stain. Vinegar can help neutralize odors and loosen residue.
    • Let it sit for 10–15 minutes, then blot thoroughly.

  3. Apply baking soda

    • After blotting, cover the area with baking soda.
    • Leave it for several hours or overnight, then vacuum.

  4. Repeat as needed

    • Very old stains might need several rounds of this process.
    • Allow full drying between treatments to avoid trapped moisture.

Is it safe to use hydrogen peroxide or stronger cleaners?

Many people wonder if stronger methods are the best way for how to get pee stains off of a mattress. They can help, but use them carefully.

  • Hydrogen peroxide (3%)

    • Often used in small amounts for light-colored mattresses.
    • Can sometimes lighten fabrics or affect dyes, so it’s wise to test on a hidden area first.
    • A common approach is to mix a small amount with dish soap and baking soda, apply lightly, let sit briefly, then blot and vacuum once dry.

  • Bleach and harsh chemicals

    • Usually not recommended for mattresses. They can damage fabric, affect foam materials, and leave strong odors.

When in doubt, start with gentler methods and only move to stronger cleaners if absolutely necessary.

How do I get rid of the pee smell from my mattress?

Even after the stain fades, odor can linger if urine has soaked deeper into the mattress.

  • Enzyme cleaners

    • Widely used for urine odors because they target the compounds that cause smells.
    • Apply according to the instructions, allow enough time to work, then blot and air dry.

  • Baking soda

    • Excellent for absorbing lingering odors.
    • After cleaning, sprinkle a generous layer over the entire affected area.
    • Leave for at least several hours, then vacuum.

  • Fresh air and time

    • If possible, air out the mattress in a well-ventilated room.
    • Avoid direct sunlight for long periods if the mattress materials may be sensitive to heat or UV.

How can I dry my mattress safely after cleaning?

A key part of how to get pee stains off of a mattress is making sure the mattress dries completely.

  • Allow plenty of air circulation (open windows, fans).
  • Use a fan or low-heat setting on a hairdryer, keeping it at a distance.
  • Avoid sleeping on the mattress until it feels fully dry, both on the surface and deeper inside.
  • If the mattress feels heavy or damp for a long time, there may be excess moisture trapped inside; more time and airflow usually help.

How do I prevent future pee stains on my mattress?

Prevention makes cleanup much easier next time.

  • Use a waterproof mattress protector to create a barrier between the sleeper and the mattress.
  • For young children, pets, or frequent accidents, consider washable mattress pads on top of the protector.
  • Address accidents as soon as possible whenever you can, since fresh stains respond better than dried ones.
