How To Get Urine Out Of Memory Foam Mattress: Step‑By‑Step FAQ

If you’re searching for “How To Get Urine Out Of Memory Foam Mattress”, you’re likely dealing with a fresh accident or a lingering stain and smell. This guide walks through exactly what to do, why it matters, and how to prevent long‑term damage and odor in your memory foam.

What should I do first when urine gets on a memory foam mattress?

Act quickly. Memory foam is highly absorbent, so the sooner you respond, the easier it is to remove urine.

  1. Remove bedding
    Strip all sheets, mattress protectors, and blankets and set them aside to wash separately.

  2. Blot, don’t rub
    Use clean, dry towels or paper towels to press firmly on the wet area.

    • Work from the edges toward the center.
    • Avoid rubbing, which can push urine deeper into the foam.

  3. Keep liquids controlled
    Memory foam should never be soaked through, so you’ll use light sprays and blotting instead of pouring water on it.

How To Get Urine Out Of Memory Foam Mattress (Fresh Stains)

What cleaning solution works best for fresh urine?

A common and gentle approach is a mild cleaning solution:

  • Mix 1 part white vinegar with 2–3 parts cool water in a spray bottle.
  • Optional: Add a small amount of mild liquid dish soap.

Vinegar helps neutralize odor and break down fresh urine without being too harsh on the foam.

How do I clean the fresh urine step by step?

  1. Test a small area
    Lightly spray an inconspicuous spot first to be sure the fabric cover reacts well.

  2. Lightly spray the stained area

    • Do not drench the mattress.
    • Aim for a slightly damp surface, not wet.

  3. Blot again
    Press with clean towels to pull the moisture back out of the foam.

  4. Apply baking soda
    Sprinkle a generous layer of baking soda over the damp area.

    • Baking soda helps absorb moisture and smells.

  5. Let it sit
    Allow it to sit for at least 8 hours, or overnight if possible, with good airflow.

  6. Vacuum thoroughly
    Use a vacuum with an upholstery attachment to remove all baking soda once dry.

If any odor remains, you can repeat the process once or twice.

How do I remove dried or old urine stains from memory foam?

Dried stains are more stubborn because urine has already soaked in and set.

Can I still clean old urine stains?

Yes, but it may take multiple treatments and some odor may linger. Focus on:

  • A slightly stronger vinegar solution (1:1 vinegar to water)
  • More time for the solution to sit on the stain (10–15 minutes)
  • Repeated cycles of spray → blot → baking soda → dry → vacuum

For persistent odor, using an enzyme-based cleaner made for fabrics and upholstery can help break down remaining urine compounds. Always:

  • Lightly mist, not drench.
  • Follow the product’s instructions.
  • Allow full drying time between applications.

Is it safe to use bleach or harsh cleaners on memory foam?

Using bleach, highly concentrated chemicals, or very hot water on memory foam can:

  • Damage the foam structure
  • Fade or weaken the mattress cover
  • Leave strong chemical smells

Avoid bleach and strong solvents. Stick to mild cleaners, diluted vinegar, and gentle, fabric-safe enzyme cleaners as needed.

How do I dry a memory foam mattress after cleaning?

Drying thoroughly is crucial to avoid musty smells or moisture damage.

  • Increase airflow: Open windows, turn on fans, or place a fan to blow across the mattress surface.
  • Use natural drying: If possible, allow the mattress to stand in a well-ventilated area for several hours.
  • Avoid direct high heat: Do not use hair dryers or heaters on high settings right against the foam, as extreme heat can damage it.

Only put bedding back on when the mattress feels completely dry to the touch.

Can urine permanently damage a memory foam mattress?

Urine can cause:

  • Lingering odors if not cleaned thoroughly
  • Yellow stains on the cover or foam
  • Possible breakdown of materials over time if accidents are frequent and not treated

However, prompt and careful cleaning often prevents long‑term issues. For severe, repeated accidents, using a waterproof mattress protector in the future can help protect the foam.

How can I prevent urine odors from returning?

To keep smells from returning:

  • Make sure the mattress is fully dry after every cleaning.
  • Use baking soda now and then as a deodorizing refresh layer (let sit a few hours, then vacuum).
  • Consider a washable mattress protector to catch any future accidents before they reach the foam.
