How To Clean Dog Pee From Mattress: Simple Steps That Actually Work

If you’re searching for how to clean dog pee from mattress, you’re likely dealing with a fresh accident or a stubborn old stain. Dog urine can leave smell, stains, and moisture trapped deep inside a mattress, but with the right steps, you can usually clean it effectively at home.

This FAQ-style guide walks you through what to do immediately, how to handle dried stains and odors, and how to help protect your mattress in the future.

Why Is Dog Pee on a Mattress Such a Problem?

Dog urine isn’t just surface-level. It can:

  • Soak into the comfort layers and core of the mattress
  • Leave behind yellow stains
  • Cause a lingering ammonia-like odor

Because you can’t just toss a mattress in the washing machine, knowing how to clean dog pee from mattress safely is important to maintain comfort and longevity.

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

Step 1: Act quickly and blot, don’t rub

  1. Remove bedding right away and set it aside to be washed.
  2. Use clean, dry towels or paper towels to blot up as much liquid as possible.
  3. Press down firmly, but do not rub, which can push urine deeper into the mattress.

The goal is to remove excess moisture before it spreads.

How To Clean Dog Pee From Mattress (Fresh Stains)

For a fresh accident, you can usually clean it with common household items.

Step 2: Apply a gentle cleaning solution

A simple approach is a mild water-and-vinegar solution:

  • Mix equal parts cool water and white vinegar in a spray bottle.
  • Lightly spray the affected area until it is damp but not soaked.
  • Let it sit for 10–15 minutes.

Vinegar helps neutralize odors and break down the urine without harsh chemicals.

Step 3: Blot again

After letting the solution sit:

  • Blot the area again with clean, dry towels.
  • Continue until you’ve absorbed as much liquid as you can.

How Do I Get Rid of the Smell?

Step 4: Use baking soda for odor control

Baking soda is commonly used to help absorb odors and moisture:

  1. Sprinkle a generous layer of baking soda over the cleaned area.
  2. Gently spread it with your hand so it covers slightly beyond the stain.
  3. Leave it in place for 8–12 hours, or overnight if possible.

Then:

  • Vacuum the baking soda thoroughly using a clean upholstery attachment.
  • Check for any lingering odor. A second light application may help if needed.

What If the Dog Pee Has Already Dried?

Old or dried urine stains are harder to remove because they’ve had more time to set into the mattress.

You can:

  • Lightly mist the area with water to re-dampen the stain (do not soak).
  • Then follow the same vinegar solution → blot → baking soda process.
  • For very stubborn stains, a mild, mattress-safe enzymatic cleaner formulated for pet urine may help break down odor-causing residues. Always spot-test first in an inconspicuous area.

Be patient: older stains may require more than one cleaning cycle.

Will Cleaning Dog Pee Ruin My Mattress?

When done carefully, spot-cleaning usually does not damage a mattress. To protect it:

  • Avoid excessive soaking, which can affect internal materials.
  • Use cool or lukewarm water, not hot, which can set stains.
  • Let the mattress dry completely before putting bedding back on.

If your mattress has a specific care tag, check it for any cleaning warnings.

How Do I Dry the Mattress After Cleaning?

Proper drying helps prevent musty smells and moisture buildup.

  • Open windows or use a fan to circulate air.
  • If possible, stand the mattress on its side to allow more airflow through the core.
  • Allow several hours for it to dry; in some cases, it may take most of the day.

Avoid using high heat devices directly on the mattress, as intense heat may affect some materials.

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

While accidents can happen, a few practical steps can make cleanup easier:

  • Use a waterproof mattress protector to create a barrier between the dog and the mattress.
  • Consider a washable mattress pad or cover on top of the protector.
  • If your dog frequently sleeps on the bed, keep extra bedding ready so you can strip the bed quickly.

These layers help ensure that any future accidents stop at the surface instead of reaching the mattress itself.
