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

If you’re searching for “How To Get Rid Of Pee Smell On Mattress,” you’re likely dealing with a fresh accident or a lingering odor that just won’t go away. This guide explains what works, what doesn’t, and how to remove both the stain and the smell as effectively as possible.

Why Does Pee Smell Linger In a Mattress?

A mattress is thick and absorbent, so urine can soak deep into the layers. Even if the surface looks clean, odor-causing compounds may remain trapped inside the foam or padding.

If the smell sticks around, it’s usually because:

  • The area wasn’t cleaned quickly enough
  • Only the surface was treated
  • Strong cleaners were used that set the stain instead of lifting it

Understanding this helps explain why you need both cleaning and deodorizing, not just one or the other.

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

1. Act Quickly (If the Stain Is Fresh)

  1. Strip all bedding and wash according to the care label.
  2. Blot, don’t rub. Use paper towels or a clean cloth to press down and absorb as much liquid as possible. Rubbing can push urine deeper into the mattress.
  3. If possible, move the mattress so the spot is accessible and can air out later.

2. Use a Gentle Cleaning Solution

For many people, a simple homemade cleaner works well:

  • Mix mild dish soap with cool water, or
  • Use a diluted white vinegar and water solution

Lightly dampen (do not soak) a cloth with the solution and gently blot the affected area. The aim is to loosen residue without saturating the mattress.

3. Neutralize Odor With Baking Soda

Once you’ve cleaned the spot:

  1. While the area is still slightly damp, sprinkle a generous layer of baking soda over the stain.
  2. Gently work it in with your fingers or a soft brush.
  3. Leave it on for several hours or overnight. The longer it sits, the more odor it may absorb.
  4. Vacuum the baking soda thoroughly using a clean upholstery attachment.

This step is often the most important in How To Get Rid Of Pee Smell On Mattress because baking soda helps neutralize odors rather than just masking them.

What If the Pee Smell Is Old or Already Dried?

Can I Still Remove Old Urine Odor?

You may not remove every trace, but you can usually reduce the smell significantly with a more focused approach:

  1. Lightly mist (do not soak) the area with a water-and-vinegar solution.
  2. Let it sit for 5–10 minutes to help re-dissolve dried residue.
  3. Blot thoroughly with clean towels.
  4. Apply a thick layer of baking soda and leave for 12–24 hours.
  5. Vacuum slowly and thoroughly.

You can repeat this process if needed, as long as you give the mattress time to dry in between.

Common Questions About Pee Smell and Mattresses

Will the pee smell go away on its own?

In many cases, no. The odor may fade slightly over time but can return, especially in warm or humid conditions. Odor removal usually requires some level of cleaning and deodorizing.

Is it safe to use strong chemicals or bleach?

Strong chemicals, including bleach and harsh solvents, can:

  • Damage mattress materials
  • Leave their own strong odors
  • Discolor fabrics

For most mattresses, mild cleaners and gentle methods are preferred. Always check the manufacturer’s care guidance if you have it.

How long does it take for a mattress to dry?

Drying time varies, but expect at least several hours. To speed this up:

  • Open windows or increase airflow
  • Use a fan pointed at the mattress
  • Avoid making the bed until it is completely dry to help prevent lingering odor and moisture buildup

How Can I Stop Pee Smells From Coming Back?

Once you’ve learned How To Get Rid Of Pee Smell On Mattress, it’s helpful to think about prevention:

  • Use a waterproof mattress protector to help keep liquids from reaching the core of the mattress.
  • Clean accidents as soon as possible so urine doesn’t have time to soak in deeply.
  • Air out your mattress occasionally, especially after a spill or wash.

These simple steps can make future cleanups quicker and reduce the chance of stubborn smells developing.
