How To Get Urine Smell Out Of Memory Foam Mattress: Simple FAQ Guide

If you’re searching for “How To Get Urine Smell Out Of Memory Foam Mattress,” you’re likely dealing with a fresh accident or a lingering odor that just won’t go away. This guide explains why memory foam holds smells, what actually works to remove urine odor, and how to prevent it from coming back.

Why does urine smell linger in a memory foam mattress?

Memory foam is highly absorbent and full of tiny air pockets. That contouring comfort that many sleepers like also means:

  • Liquid soaks in quickly, especially if not cleaned right away
  • Odor-causing residues can get trapped deep in the foam
  • Standard surface cleaning may not reach all of the affected areas

Urine contains proteins, salts, and urea, which can dry into the foam and create a stubborn smell if not neutralized properly.

First steps: What should I do right after a urine accident?

Acting quickly gives you the best chance of getting urine smell out of a memory foam mattress.

  1. Remove bedding immediately
    Take off sheets, protectors, and mattress covers so the urine doesn’t spread.

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

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

  3. Keep the mattress flat
    If possible, leave the mattress flat so urine doesn’t run to other areas or down the sides.

These initial steps help limit how far the urine penetrates, making odor removal easier.

How To Get Urine Smell Out Of Memory Foam Mattress: Step‑by‑Step

Here’s a simple process many people use at home with common cleaning ingredients.

1. Apply a gentle cleaning solution

Mix a solution of cool water and mild, clear dish soap or a small amount of gentle laundry detergent.

  • Lightly spray the affected area—do not soak the mattress
  • Blot with a clean cloth to lift out as much urine as possible

This helps remove some of the residue before you work on the smell.

2. Use an odor-neutralizing mixture

For many urine smells, a water and white vinegar mixture can help neutralize odors.

  • Mix equal parts white vinegar and water in a spray bottle
  • Lightly spray the stained area until it is damp but not saturated
  • Let it sit for 5–10 minutes, then gently blot again

Vinegar has a strong scent at first, but it usually fades as it dries.

3. Deodorize with baking soda

Baking soda can help draw out moisture and absorb lingering odors.

  • Sprinkle a generous layer of dry baking soda over the treated area
  • Gently press it into the surface of the foam
  • Leave it on for at least several hours, or overnight if possible
  • Vacuum the baking soda thoroughly

If the smell is still noticeable, you can repeat the vinegar and baking soda steps once more.

What if the urine smell is old or set in?

Dried urine can be more stubborn, but the same basic approach still applies.

Should I clean differently for old stains?

For older stains:

  • Spend extra time blotting with the soapy water solution to re-dissolve dried residue
  • Follow with the vinegar solution and baking soda as above
  • You may need to repeat the cycle multiple times for a noticeable improvement

Avoid harsh cleaners or strong chemicals, which can damage memory foam or leave their own strong smells behind.

Can I use hot water, steam cleaners, or a washing machine?

Is hot water a good idea?

Hot water can sometimes set stains and odors, making them more difficult to remove. Cool or slightly warm water is generally safer for both odor removal and the foam’s structure.

What about steam cleaners?

Steam cleaners can push moisture deep into the foam, making it hard to dry fully. Excess moisture trapped inside memory foam can lead to musty smells over time. Many mattress owners choose to avoid steam cleaning for this reason.

Can I put a memory foam mattress in the washing machine?

No. Memory foam should not go in a washing machine. Agitation and soaking can damage the structure of the foam, and it may never dry properly.

How do I dry my mattress after cleaning?

After you’ve followed the cleaning steps:

  • Increase airflow with open windows or fans
  • If possible, stand the mattress on its side (once it’s only slightly damp) to let air reach more surfaces
  • Avoid using very high heat directly on the foam; gentle warmth and time are usually enough

A memory foam mattress may take many hours to fully dry. Ensure it’s completely dry before putting bedding back on to help prevent lingering odors.

How can I prevent urine smells in the future?

A little prevention can make cleaning much easier next time.

  • Use a water-resistant or waterproof mattress protector
  • Clean small spills or accidents as soon as you notice them
  • Air out your mattress periodically by removing bedding and allowing airflow

These habits can help keep your mattress fresher for longer.

✔️ Quick Mattress Takeaways

Key points consumers should understand about How To Get Urine Smell Out Of Memory Foam Mattress

  • Act fast: Blot up fresh urine immediately to stop it soaking deeper into memory foam.
  • Blot, don’t scrub: Press with dry towels to lift liquid; scrubbing can spread the stain.
  • Use gentle solutions: Cool water, mild soap, vinegar solution, and baking soda are commonly used for odor removal.
  • Avoid oversoaking: Memory foam can hold water; too much liquid makes drying difficult and may worsen odors.
  • Dry thoroughly: Good airflow and enough time are essential before re-making the bed.
  • Expect repeats for old stains: Set-in urine smells may require multiple cleaning rounds.
  • Protect going forward: A washable mattress protector can greatly reduce future odor and stain issues.
