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

If you’re searching for how to clean dog pee off mattress, you’re likely dealing with a fresh accident or trying to fix an old, smelly stain. This guide walks you through what to do right away, how to tackle dried stains, and how to reduce lingering odours without damaging your mattress.

What’s the Best First Step When Dog Pee Hits Your Mattress?

Acting quickly is the most important part of how to clean dog pee off mattress.

  1. Remove bedding immediately
    Strip sheets, protectors, and covers and set them aside for washing.

  2. Blot, don’t rub
    Use clean, dry towels or paper towels to press firmly into the wet area.

    • Work from the outside of the stain inward.
    • Avoid scrubbing, which can push urine deeper into the mattress.

  3. Prepare a simple cleaning solution
    A common home approach is:

    • 1 part mild liquid soap to 4–5 parts cool water
    • Or a mix of white vinegar and water (about equal parts) for odour control

Always start with a small amount of liquid; mattresses absorb moisture easily, and too much can be hard to dry.

How Do You Deep-Clean Dog Pee From a Mattress?

Once you’ve blotted up as much as possible, you can move on to deeper cleaning.

Step-by-step method for fresh stains

  1. Lightly apply cleaner

    • Use a spray bottle to lightly mist the stained area with your chosen solution.
    • The goal is to dampen the fibres, not soak the mattress.

  2. Gently blot again

    • Press with a clean towel to pull out both the urine and cleaner.
    • Repeat spraying and blotting a few times as needed.

  3. Use baking soda for odour

    • Sprinkle a generous layer of dry baking soda over the treated area.
    • Gently pat it in and leave it for several hours, or overnight if possible.

  4. Vacuum thoroughly

    • Once the baking soda is completely dry, vacuum it slowly using an upholstery attachment.
    • This helps remove both residue and odour.

This simple routine covers most fresh dog urine accidents and is often all that’s needed for light stains.

How To Clean Dog Pee Off Mattress When It’s Already Dried?

Dried stains can be more stubborn because the urine has had time to set and crystalize in the mattress.

  1. Re-dampen the area lightly

    • Mist the stained area with a vinegar-and-water solution or mild soap-and-water mixture.
    • Let it sit for 10–15 minutes to help loosen the dried residue.

  2. Blot repeatedly

    • Use clean, dry towels to pull up as much moisture as possible.
    • Rotate to fresh areas of the towel so you’re not pressing moisture back in.

  3. Target lingering odours

    • Cover the area with baking soda again and leave it for at least several hours.
    • For strong smells, leaving it on for a full day can be helpful.

  4. Vacuum and inspect

    • Vacuum thoroughly and check for remaining stain and smell.
    • If needed, repeat once more rather than over-soaking in a single attempt.

If a stain still won’t budge after a couple of careful attempts, it may be set into the deeper layers of the mattress, where home methods have limited reach.

Will Dog Pee Ruin My Mattress?

Dog urine can be tough on a mattress, but one accident rarely means it’s ruined.

Why it matters:

  • Odour can linger if urine soaks deeply and isn’t cleaned quickly.
  • Discolouration may remain even after odour is reduced, especially on light fabrics.
  • Moisture trapped inside the mattress can encourage general unpleasantness over time.

The faster you respond, the better your chances of avoiding permanent smells and stains.

How Can I Dry the Mattress Safely After Cleaning?

Drying is a key part of how to clean dog pee off mattress effectively.

  • Increase airflow: Open windows and use a fan aimed at the mattress.
  • Use indirect warmth: A warm, dry room helps, but avoid placing a mattress directly in strong sun or using high-heat sources that could damage materials.
  • Allow enough time: Make sure the mattress is fully dry before putting bedding back on, especially if you used more than a light mist.

If the mattress still feels cool or slightly damp to the touch, give it more time.

Can I Use Strong Chemicals or Fragrances?

It can be tempting to grab whatever is under the sink, but some products are too harsh for mattress fabrics and foams.

  • Avoid bleach or highly concentrated cleaners, which may discolor or weaken materials.
  • Be careful with heavy fragrances, which might only cover odours temporarily or irritate sensitive sleepers.
  • Always test a small hidden area first if you’re unsure how a cleaner will react.

Gentler, simple solutions are usually enough for occasional accidents.

✔️ Quick Mattress Takeaways

Key points to understand about how to clean dog pee off mattress:

  • Act fast: Blot up fresh urine immediately before it soaks deeper.
  • Go light on liquids: Use misted cleaner and blotting instead of soaking the mattress.

  • Dried stains need patience: Re-dampen, blot, and repeat rather than over-saturating once.
  • Dry thoroughly: Good airflow and time are essential to prevent lingering smells.
  • Gentle wins: Mild cleaners are usually better for mattress materials than harsh chemicals.
