How To Get Rid Of Dog Urine On Mattress: Step‑by‑Step FAQs

If you’re searching for “How To Get Rid Of Dog Urine On Mattress,” you’re likely dealing with a fresh accident or an older, lingering stain. This guide walks through what to do right away, how to remove odor and staining, and how to prevent repeat issues, all in a clear FAQ format.

What should I do first when my dog pees on the mattress?

Acting quickly is the best way to protect your mattress.

  1. Strip the bed
    Remove sheets, mattress protectors, and any blankets. Wash them separately following their care labels.

  2. Blot, don’t rub
    Use clean, dry towels or paper towels to press firmly on the wet area. The goal is to soak up as much urine as possible.

    • Avoid rubbing, which can push urine deeper into the mattress core.

  3. Check how deep the stain goes
    Gently press around the wet spot. If the mattress feels soaked, you may need to repeat blotting several times before using any cleaning solution.

How do I clean fresh dog urine from a mattress?

Once you’ve blotted up the excess, you can start cleaning.

Basic cleaning method for fresh urine:

  • Mix a solution of equal parts white vinegar and water.
  • Lightly spray or gently pour enough to dampen (not drench) the stained area.
  • Let it sit for 10–15 minutes.
  • Blot again with clean, dry towels to remove excess moisture.
  • Sprinkle baking soda generously over the damp area.
  • Leave the baking soda on for several hours, or ideally overnight.
  • Vacuum up the baking soda once it’s completely dry.

This approach helps neutralize odor and break down the urine, which is key when learning how to get rid of dog urine on mattress surfaces effectively.

How do I remove dried or old dog urine stains?

Old stains are more stubborn because they’ve had time to set into the foam or padding.

For dried stains:

  1. Rehydrate the spot
    Lightly spray the area with a 50/50 vinegar and water solution to loosen dried urine.

  2. Let it sit
    Allow 15–20 minutes of contact time so the solution can penetrate.

  3. Blot thoroughly
    Press with clean towels until you’ve removed as much liquid as possible.

  4. Apply baking soda
    Cover the area with a thick layer of baking soda and leave for at least 8 hours or until completely dry.

  5. Vacuum
    Slowly vacuum the powder to lift dried residue and odor.

You may need to repeat the process for older, darker stains or persistent smells.

How can I get rid of the urine smell completely?

Dog urine can leave behind a strong, lingering odor if not fully removed.

To tackle odor:

  • Use white vinegar: It helps neutralize many urine odors.
  • Use baking soda: It absorbs smells over time.
  • Allow full drying time: A mattress that stays slightly damp can trap odors.

For strong smells that remain after cleaning, a second round of treatment and extended drying time often helps. Some people also open windows or use a fan to increase airflow and help odors dissipate.

Is it safe to use bleach or harsh chemicals on a mattress?

Using bleach or strong chemicals on a mattress is usually not recommended:

  • They can damage fabrics and foam.
  • Residue may be irritating to skin or airways.
  • Strong scents can be difficult to remove and may linger.

Milder options like diluted vinegar and baking soda are generally used instead for mattress cleaning & stain removal at home.

How long does it take the mattress to dry?

Drying time depends on:

  • Mattress material and thickness
  • Room temperature and humidity
  • Airflow (windows open, fans running)

In many cases, expect at least several hours. For safety and comfort:

  • Make sure the mattress is completely dry before putting sheets back on.
  • Use a fan, open windows, or gently move the mattress for better ventilation if possible.
  • Avoid using direct high heat for long periods, which could affect some mattress materials.

Will dog urine permanently damage my mattress?

Dog urine can cause:

  • Discoloration (staining)
  • Odor that’s difficult to remove if left untreated
  • Possible breakdown of some materials if exposure is repeated and not cleaned

However, quick and thorough cleaning often reduces visible and odor-related damage. Even with older stains, careful cleaning can usually improve the look and smell of the mattress, though some light staining may remain.

How can I prevent future dog urine accidents on my mattress?

A few simple habits can make accidents easier to handle:

  • Use a waterproof mattress protector to create a physical barrier.
  • Keep washable blankets or covers on top for extra protection.
  • Address house training or nighttime routines with your dog so accidents are less likely.
  • Clean any new accidents immediately, using the same steps each time.

These strategies can help limit how often you need to search for how to get rid of dog urine on mattress and lengthen your mattress’s usable life.
