How To Get Dog Pee Smell Out Of a Mattress: Step‑by‑Step FAQ Guide

If you’re searching for how to get dog pee smell out of a mattress, you’re likely dealing with an accident that left both a stain and a lingering odor. This guide walks you through practical, home-friendly methods to remove the smell, protect your mattress, and reduce the chance of repeat accidents.

Why Does Dog Pee Smell Linger in a Mattress?

Dog urine can soak deep into the layers of a mattress. As it dries, it can leave behind:

  • Odor-causing compounds that cling to fabric and foam
  • Stains that may become harder to remove over time
  • A scent marker that can encourage your dog to return to the same spot

Because of this, acting quickly and using the right cleaning steps is important for getting both the stain and smell out effectively.

What Should I Do First When My Dog Pees on the Bed?

1. Blot, Don’t Rub

Use clean, dry towels or paper towels to blot up as much liquid as possible. Press down firmly to pull moisture out of the mattress. Avoid rubbing, which can spread the urine and push it deeper.

2. Strip the Bed

Remove all bedding, including mattress protectors or toppers, and wash them according to their care labels.

3. Ventilate the Room

Open windows or turn on a fan if possible. Good airflow helps the mattress dry more quickly after cleaning.

How To Get Dog Pee Smell Out Of a Mattress Using Common Household Ingredients

Here’s a straightforward method many people use with items they already have at home.

Step 1: Apply a Vinegar Cleaning Solution

Mix a simple solution:

  • 1 part white vinegar
  • 1 part water

Lightly spray or gently pour just enough to cover the affected area without soaking the entire mattress. Vinegar helps neutralize the urine odor.

Let it sit for about 10–15 minutes, then blot thoroughly with clean, dry towels to remove excess moisture.

Step 2: Use Baking Soda to Deodorize

Generously sprinkle baking soda over the damp area. Baking soda is often used to absorb odors from fabrics and soft surfaces.

Leave it on the mattress for at least several hours, and ideally overnight, so it has time to work.

Step 3: Vacuum the Mattress

Once the baking soda is completely dry, vacuum it up using a vacuum with an upholstery attachment. This helps remove odor-absorbing powder and any loosened residue from the stain.

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

Can I Use Enzyme Cleaners on Dog Urine?

Many people find enzyme-based cleaners helpful for pet accidents. These cleaners are designed to break down urine components that cause lingering smell.

If you use one:

  • Follow the instructions on the label
  • Test a small, hidden area of the mattress first
  • Avoid mixing it with vinegar or other cleaners at the same time

Using a dedicated pet-safe cleaner can be especially useful for older stains or strong odors that don’t fully respond to vinegar and baking soda alone.

What If the Dog Pee Smell Is Old or Already Dried In?

Old or dried urine can be more challenging, but you can still improve it:

  • Rehydrate the area lightly with the vinegar and water solution
  • Let it sit, then blot as much as possible
  • Apply baking soda and leave it longer, up to 24 hours
  • Consider repeating the process or adding an enzyme cleaner step if needed

In some cases, very deep or extensive staining may never disappear completely, but consistent cleaning can significantly reduce the odor.

Is It Safe to Use Bleach or Harsh Chemicals on a Mattress?

Using bleach or strong chemical cleaners on a mattress is generally not recommended because they can:

  • Damage the mattress materials
  • Leave their own strong smell
  • Be difficult to rinse out fully

Gentler options like diluted vinegar, baking soda, and appropriate upholstery or enzyme cleaners are usually preferred for mattress care.

How Long Will It Take the Mattress to Dry?

Drying time depends on how much liquid was used and room conditions. To help it dry:

  • Use a fan or circulate air in the room
  • Avoid making the bed until the mattress feels fully dry to the touch
  • Try not to sleep directly on a damp area, as trapped moisture can lead to other issues

Many people find that a lightly treated area can dry within a day, while heavier cleaning may take longer.

How Can I Prevent Future Dog Pee Accidents on My Mattress?

While accidents can still happen, a few steps may help protect your mattress:

  • Use a waterproof mattress protector to create a barrier against liquids
  • Keep a cleaning kit handy (towels, vinegar, baking soda, pet cleaner)
  • Encourage your dog to sleep on washable bedding placed on top of the mattress or nearby

These measures won’t stop all accidents, but they can make cleanup faster and easier next time.

✅ Quick Mattress Takeaways
