How To Get Dog Urine Smell Out Of My Mattress: Simple Steps That Work

If you’re searching for “How To Get Dog Urine Smell Out Of My Mattress,” you’re likely dealing with a fresh accident, an old stain, or a lingering odor that just won’t go away. This guide walks you through practical, mattress-safe methods to remove both the stain and the smell, and answers the most common questions pet owners have.

Why Does Dog Urine Smell Linger In a Mattress?

Dog urine can soak deep into the mattress layers, especially if:

  • The accident isn’t cleaned up right away
  • The mattress cover isn’t waterproof
  • Only the surface is cleaned, leaving odor-causing residues inside

Urine contains proteins and salts that can trap odors in foam and fabric. That’s why simply spraying a fragrance or using regular soap often isn’t enough.

First Steps: What Should I Do Right After My Dog Pees on the Bed?

How do I handle fresh urine?

For a recent accident, speed makes a big difference:

  1. Remove bedding immediately
    Strip sheets, covers, and protectors so the urine doesn’t spread.

  2. Blot, don’t rub
    Use dry, absorbent towels or paper towels to press firmly on the wet spot.

    • Work from the outside in to prevent spreading.
    • Keep blotting with clean sections until no more moisture lifts.

  3. Avoid harsh cleaners
    Strong chemicals or bleach can damage mattress materials and may not remove the smell effectively.

At this stage, the goal is to remove as much liquid as possible before it can soak deeper.

How To Get Dog Urine Smell Out Of My Mattress: Step-by-Step

What cleaning solution works best?

A simple, commonly used approach combines vinegar, water, and baking soda:

  1. Make a cleaning solution

    • Mix equal parts white vinegar and water in a spray bottle.
    • Vinegar helps neutralize many odors.

  2. Lightly saturate the stained area

    • Spray enough solution to reach where the urine did, but avoid soaking the entire mattress.
    • Let it sit for 10–15 minutes.

  3. Blot again

    • Use clean, dry towels to absorb the vinegar solution.
    • Press firmly to draw out moisture from deeper layers.

  4. Apply baking soda

    • Sprinkle a generous layer of dry baking soda over the damp area.
    • This helps absorb remaining moisture and odor.

  5. Let it dry completely

    • Leave the baking soda on for several hours, or ideally overnight.
    • Ensure good airflow by opening windows or using a fan.

  6. Vacuum thoroughly

    • Once dry, vacuum up all the baking soda from the mattress surface.

This method is widely used for spot-treating smells and can be repeated if any odor remains.

What If the Dog Urine Smell Is Old or Already Dried?

Can I still remove an old urine odor?

Dried stains can be more stubborn, but they’re often still manageable:

  • Re-wet the area lightly with the vinegar-and-water solution described above.
  • Let it sit longer (up to 20–30 minutes) so it can reach older residues.
  • Blot thoroughly and repeat the baking soda and vacuum process.

You may need to repeat the whole routine more than once for long-standing smells.

Is It Safe to Use Enzyme Cleaners on a Mattress?

Many people use enzymatic cleaners formulated for pet urine. These products are typically designed to break down odor-causing components in urine.

If you choose to use one:

  • Check that it’s labeled as safe for fabric and foam.
  • Test it first on a small, hidden area of the mattress.
  • Follow the instructions carefully and allow full drying time.

Avoid over-saturating the mattress, as too much liquid can lead to slow drying and possible damage.

How Can I Dry the Mattress Properly After Cleaning?

Drying is just as important as cleaning when you’re figuring out how to get dog urine smell out of my mattress:

  • Place the mattress in a well-ventilated room.
  • Use fans to speed evaporation.
  • If possible, place the mattress in indirect sunlight, which can help with odor.

Do not make the bed again until the mattress feels completely dry to the touch.

How Do I Stop the Smell From Coming Back?

Even after odor removal, future accidents can bring the smell back if the mattress isn’t protected.

📝 Simple prevention tips:

  • Use a waterproof mattress protector to keep liquid from reaching the mattress.
  • Wash bedding promptly after any accident.
  • Address repeated accidents by giving your dog extra chances to go outside and consulting appropriate resources if needed (without making health assumptions).
