How Do You Get Urine Smell Out Of a Mattress? Step‑by‑Step Guide

If you’re searching for “How Do You Get Urine Smell Out Of a 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 works, what to avoid, and how to keep your mattress fresh without harming the materials.

Why Does Urine Smell Linger in a Mattress?

Mattresses are thick, porous, and usually covered in absorbent fabric. Urine can soak deep into the comfort layers, where:

  • The liquid is hard to fully reach and dry.
  • Odor-causing compounds can remain even after surface cleaning.
  • Warm, slightly damp areas can hold onto smells longer.

The longer urine sits, the harder it usually is to remove both the stain and the smell, which is why acting quickly often gives the best result.

How Do You Get Urine Smell Out Of a Mattress? (Core Method)

The most common home method combines blotting, gentle cleaning, odor neutralizing, and thorough drying.

Step 1: Blot Up as Much as Possible

For fresh accidents:

  1. Remove all bedding.
  2. Use clean, dry towels or paper towels.
  3. Press and blot (do not rub) to lift out as much liquid as possible.

Rubbing can push urine deeper into the mattress instead of lifting it out.

Step 2: Apply a Mild Cleaning Solution

You can use a simple water-based cleaning solution:

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

Lightly spray or dab the solution onto the affected area. Avoid soaking the mattress; too much liquid can spread the stain and prolong drying. Blot again to remove excess moisture.

Step 3: Neutralize Odor With a Common Household Deodorizer

Many people find that a basic deodorizing powder helps with smell:

  1. Sprinkle a generous layer over the damp, treated area.
  2. Gently press it into the fabric surface.
  3. Leave it on for several hours, or preferably overnight, to absorb odors.

Afterward, vacuum thoroughly to remove the powder from the mattress surface.

Step 4: Let the Mattress Dry Completely

Proper drying is crucial to get the urine smell out of a mattress:

  • Allow for good air circulation in the room.
  • If possible, stand the mattress on its side.
  • Use a fan to help speed up drying.

Avoid placing the mattress back in use until it feels fully dry to the touch. A slightly damp core can hold onto odor.

What If the Urine Smell Is Old or Strong?

Old or repeated accidents can be more stubborn. You can:

Go Through the Cleaning Steps Twice

Sometimes repeating the process is necessary. If the smell is still noticeable, a second round of cleaning and deodorizing may help reach deeper layers.

Focus on a Smaller, Deeper Area

For targeted odor:

  • Concentrate cleaning and deodorizing in the center of the original spot, where liquid likely pooled.
  • Use less liquid overall, but apply it more precisely.

When Is It Hard to Remove the Smell Completely?

The urine smell may be difficult to fully remove when:

  • The mattress has been soaked multiple times.
  • The accident happened long ago and was never cleaned well.
  • The mattress materials are very absorbent and thick.

In these cases, reducing the smell is often realistic, but completely removing it may be challenging.

Is It Safe to Use Harsh Chemicals on a Mattress?

Many consumers wonder if strong cleaners will work better. It’s important to:

  • Avoid overly harsh or highly concentrated products that could damage fabric or foam.
  • Be cautious with products that produce a lot of moisture or heavy residue.
  • Test any cleaner on a small, hidden area first to check for discoloration or texture changes.

A gentle, gradual approach usually balances odor removal with material safety.

How Can You Prevent Future Urine Smells in a Mattress?

Prevention makes cleaning much easier:

  • Use a washable, waterproof mattress protector to keep liquids from reaching the mattress.
  • Clean accidents as soon as possible to avoid deep absorption.
  • Air out your mattress occasionally by removing bedding and allowing fresh air circulation.

These simple steps often reduce the need for more intensive cleaning later.
