How To Get Rid Of Pee Smell In Mattress: Simple Steps That Actually Help

If you’re searching for “How To Get Rid Of Pee Smell In Mattress”, you’re likely dealing with a fresh accident or a lingering odor that just won’t go away. This guide walks you through what to do immediately, how to tackle old smells, and what to avoid so you don’t make the stain or scent worse.

Why Does Pee Smell Linger In a Mattress?

Urine soaks deep into the mattress layers, not just the surface. Even after the visible stain fades, odor-causing residues can remain trapped inside the foam or padding.

Mattresses are also thick and slow to dry. If moisture stays inside, smells can persist or even intensify over time. That’s why simply spraying air freshener or using a lightly scented cleaner usually isn’t enough.

How To Get Rid Of Pee Smell In Mattress: Step-by-Step

This basic method works for many fresh and some older accidents.

1. Act Fast (For Fresh Accidents)

  1. Remove bedding and wash it promptly.
  2. Blot, don’t rub the wet spot with clean, dry towels or paper towels to soak up as much liquid as possible.
  3. Continue blotting until the area feels only slightly damp.

Rubbing can push urine deeper into the mattress and spread the stain.

2. Use a Gentle Cleaning Solution

Many people find a simple mixture works well:

  • Cool or lukewarm water
  • A small amount of mild liquid soap or gentle detergent

Lightly dab this solution onto the stained area with a cloth or sponge, then blot dry again. The goal is to lift the residue, not soak the mattress.

3. Neutralize Odor With Baking Soda

Baking soda is often used to help absorb smell and moisture:

  1. Sprinkle a generous layer of baking soda over the treated area.
  2. Gently spread it out so it covers a bit beyond the stain.
  3. Leave it for several hours, or ideally overnight, to work.

Once the baking soda has sat for long enough, vacuum it thoroughly using an upholstery attachment if possible.

What If the Pee Smell Is Old or Very Strong?

Old urine stains can be more stubborn, but you can still try:

1. Repeat the Cleaning Process

Sometimes, more than one round of gentle cleaning and baking soda helps. Allow the mattress to dry fully between attempts.

2. Allow Extra Drying Time

After cleaning, make sure the mattress is completely dry before putting bedding back on. If possible:

  • Open windows for airflow
  • Use a fan pointed at the mattress
  • Avoid sleeping directly on the damp area

Trapped moisture can contribute to persistent odors.

3. Consider When It Might Be Too Deep

If a large amount of urine has soaked into the mattress over time, or if the smell remains after several careful cleanings, it may be due to deep saturation in the inner layers. In such cases, surface cleaning has limits, and ongoing odor can be difficult to remove completely.

Common Questions About Pee Smell Removal

Can I use very hot water or steam cleaners?

Using very hot water or steam directly on a mattress can push moisture and residues further inside and make drying harder. This can sometimes worsen odors. Many people prefer cooler or lukewarm water and light moisture instead of heavy soaking.

Do strong fragrances or air fresheners fix the problem?

Fragrances may mask the smell for a short time, but they usually don’t remove the underlying cause. For long-term results, removing or neutralizing the urine residue is more important than covering it up.

Is it safe to use harsh chemicals?

Harsh or heavily scented cleaners can:

  • Irritate skin or airways for some sleepers
  • Leave their own chemical smell in the mattress
  • Potentially damage certain mattress materials

Many people stick to gentler cleaning solutions and small test spots first to avoid issues.

How To Prevent Future Pee Smell in a Mattress

You can reduce the chances of dealing with this again by:

  • Using a water-resistant mattress protector
  • Cleaning accidents as soon as possible
  • Allowing the mattress to dry thoroughly after any spill or cleaning

Quick action and good protection often make the biggest difference.
