How Can I Get Pee Smell Out Of a Mattress? Simple Steps That Actually Help

If you’re searching “How Can i Get Pee 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 practical, home-friendly methods to remove pee smell from a mattress and keep it fresher in the future.

Why Does Pee Smell Linger in a Mattress?

Mattresses are made of layers of foam and fabric that easily absorb liquid. When urine soaks in:

  • The moisture travels deep into the layers
  • Salts and compounds in urine can crystalize and dry in the fibers
  • Over time, these can lead to a persistent, sour or ammonia-like odor

That’s why simply wiping the surface or spraying air freshener doesn’t work. You need to clean, neutralize, and fully dry the area.

How Can I Get Pee Smell Out Of a Mattress Fast?

The faster you act, the easier it is to remove the smell. Here’s a common at-home method for fresh accidents.

Step 1: Blot, Don’t Rub

  • Remove bedding right away.
  • Use clean, dry towels or paper towels to blot up as much urine as possible.
  • Press firmly, but avoid scrubbing, which can spread the stain deeper.

Step 2: Apply a Gentle Cleaning Solution

Many people use mild household ingredients:

  • Mix 1 part white vinegar with 1–2 parts water in a spray bottle.
  • Lightly spray the affected area (don’t soak the entire mattress).
  • Vinegar helps break down the odor-causing components of urine.

Let it sit for about 10–15 minutes so it can reach below the surface.

Step 3: Blot Again

  • Blot the area with fresh towels to remove excess moisture.
  • Press down firmly to draw out as much liquid as you can.

How Does Baking Soda Help With Pee Smell?

Baking soda is widely used because it can absorb odors and moisture from soft surfaces.

Step 4: Cover With Baking Soda

  • Sprinkle a generous layer of baking soda over the damp area.
  • Gently pat it to help it contact the mattress surface.
  • Leave it on for at least several hours, and ideally overnight, so it can absorb both odor and leftover moisture.

Step 5: Vacuum Thoroughly

  • Once the baking soda is dry and clumpy, vacuum it up slowly.
  • Use a clean upholstery attachment if you have one.
  • Check for remaining odor. If needed, you can repeat the process.

What If the Pee Smell Is Old or Already Dried?

Dried urine can be tougher to manage, but many of the same steps still apply.

Rehydrate and Treat the Area

  1. Lightly spray a vinegar-and-water mix onto the dried spot.
  2. Let it sit to re-dissolve the dried urine crystals.
  3. Blot, then apply baking soda as before.

For very stubborn smells, some people repeat this two or three times over a few days, allowing full drying between treatments.

Is It Safe to Use Strong Cleaners on a Mattress?

Many sleepers wonder if they should use harsh chemicals or strong fragrances to get rid of urine odor. A few points to consider:

  • Strong chemicals may discolor fabrics or break down foam over time.
  • Heavy fragrances can mask smells but may not actually remove them.
  • Always test any cleaner on a small, hidden area first to check for discoloration.
  • Avoid soaking the mattress, which can trap moisture and lead to other odors.

When in doubt, milder solutions (like diluted vinegar plus baking soda) are often preferred for routine cleanup.

How Long Does It Take for Pee Smell to Go Away?

Time depends on:

  • How much urine soaked into the mattress
  • How quickly you treated it
  • How well you allowed the mattress to dry and air out

After a careful clean, many people notice a clear improvement within a day or two. If the smell lingers, revisiting the cleaning steps or letting the mattress air out in a well-ventilated room can help.

Can I Prevent Future Pee Smells in My Mattress?

You can’t always prevent accidents, but you can help protect your mattress:

  • Use a water-resistant mattress protector to keep liquids from sinking in
  • Wash bedding promptly after accidents
  • Blot and treat spills as soon as you notice them
  • Let the mattress fully dry before putting sheets back on
