How Clean Urine From Mattress: Simple Steps and FAQs

If you’re searching for “How Clean Urine From Mattress”, you’re likely dealing with a fresh accident or an older stain that just won’t go away. This guide walks through practical, at-home steps to remove urine, reduce odour, and help protect your mattress, all in a calm, straightforward way.

What’s the best way to clean fresh urine from a mattress?

Fresh urine is usually easier to manage than dried stains. Acting quickly can make a big difference.

Step-by-step method for fresh urine:

  1. Strip the bed
    Remove sheets, protector (if you have one), and any blankets. Wash these separately following their care labels.

  2. Blot, don’t rub
    Use clean, dry towels or paper towels to blot up as much liquid as possible.

    • Press firmly to soak it up.
    • Avoid scrubbing, which can push urine deeper into the mattress.

  3. Apply a gentle cleaning solution
    In a spray bottle, mix:

    • 1 part mild liquid dish soap
    • 4–5 parts cool water
      Lightly spray the affected area. Do not soak the mattress; use just enough to dampen the surface.

  4. Blot again
    Use a clean cloth to blot the area, lifting out the soapy solution and remaining urine.

  5. Rinse lightly
    Mist with plain cool water and blot again. Repeating this once or twice helps remove soapy residue.

  6. Dry thoroughly

    • Place clean, dry towels over the damp spot and press down.
    • Allow the mattress to air-dry completely before making the bed. Good airflow and time are important.

How do I remove dried urine stains and odours?

Dried urine can leave visible stains and lingering smells. It often needs a bit more attention.

Using a vinegar-based approach

A common home method involves white vinegar and baking soda:

  1. Lightly apply white vinegar solution
    Mix equal parts white vinegar and cool water in a spray bottle. Lightly spray the stained area. Vinegar can help break down uric compounds that contribute to odour.

  2. Let it sit
    Allow the area to sit for about 10–15 minutes so the solution can work on the stain.

  3. Blot thoroughly
    Blot with clean, dry cloths to remove as much moisture as possible.

  4. Sprinkle baking soda
    Generously cover the damp area with baking soda. Baking soda is often used to absorb odours and excess moisture.

  5. Leave for several hours
    Let the baking soda sit for at least a few hours, or ideally overnight, until it dries and clumps.

  6. Vacuum
    Vacuum the dried baking soda using an upholstery attachment.

If odour or discolouration remains, this process can sometimes be repeated.

Can I use hydrogen peroxide to clean urine from a mattress?

Hydrogen peroxide is sometimes used on light-coloured, non-delicate fabrics for tough stains, but there are a few points to consider:

  • It may lighten or discolor certain mattress fabrics or covers.
  • It may affect delicate materials or finishes over time.

If you decide to try it, test a small, hidden area first. Many people use a gentle mix of hydrogen peroxide, mild soap, and baking soda, applied sparingly and then blotted and dried thoroughly. Always avoid oversaturating the mattress.

How Clean Urine From Mattress: Common Questions

Will urine permanently damage my mattress?

Urine can:

  • Leave stains and odours if not cleaned well
  • Attract moisture-related issues inside the mattress if it repeatedly soaks in

Cleaning promptly and drying completely helps reduce long-term effects. A single, well-cleaned accident is less likely to cause significant structural damage than repeated, unaddressed accidents.

How do I get rid of lingering urine smell?

If the smell lingers after cleaning:

  • Repeat the vinegar and baking soda method.
  • Ensure the mattress is truly dry all the way through; trapped moisture can hold odour.
  • Air out the room by opening windows or improving ventilation around the bed.

For very strong or long-standing odours, multiple gentle treatments may be needed.

Is it safe to sleep on the mattress the same night?

It’s important that the mattress is completely dry before putting on fresh bedding and sleeping on it. A damp mattress can feel uncomfortable and may encourage odour or moisture problems inside the bed. If the mattress is still cool or damp to the touch, allow more drying time.

How can I prevent future urine stains on my mattress?

You can’t always avoid accidents, but you can often protect the mattress itself:

  • Use a water-resistant or waterproof mattress protector to create a barrier.
  • Consider absorbent pads or covers for children, pets, or anyone prone to accidents.
  • Address spills and accidents as soon as you notice them to keep liquids from soaking deeply into the mattress.
