How To Clean Dog Pee From a Mattress: Step-by-Step FAQ Guide

Waking up to a wet spot on your bed is stressful, but learning how to clean dog pee from a mattress can save your mattress and your sleep. This FAQ-style guide walks you through what to do right away, how to remove odor and stains, and how to handle dried or repeated accidents.

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

Act quickly. Fresh urine is much easier to remove than dried stains.

  1. Strip the bed
    Remove sheets, mattress protectors, and bedding right away and wash them according to their care labels.

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

    • Blot from the outside of the stain toward the center.
    • Avoid scrubbing, which can push urine deeper into the mattress.

  3. Check how deep the moisture goes
    Press your hand gently on the area to feel how far the moisture has spread. This helps you treat the full affected area, not just the visible spot.

How do I clean fresh dog pee from a mattress?

Here is a simple method many people use at home:

  1. Apply a mild cleaning solution
    Mix a solution of:

    • 1 part white vinegar
    • 2–3 parts cool water

    Lightly spray or dab this onto the stain. The vinegar helps break down urine residues and neutralize odor. Avoid soaking the mattress, as too much liquid can be hard to dry.

  2. Let it sit
    Allow the solution to sit for about 10–15 minutes to work on the stain.

  3. Blot again
    Use clean towels to blot up as much moisture as possible. The more liquid you remove now, the easier it will be to dry and deodorize.

  4. Use baking soda to absorb moisture and odor
    Sprinkle a generous layer of baking soda over the damp area. Gently spread it so it covers slightly beyond the visible stain.

    • Leave it on for several hours, or overnight if possible.
    • Baking soda can help absorb remaining moisture and reduce lingering smell.

  5. Vacuum thoroughly
    Once the baking soda is completely dry, vacuum it up slowly. Go over the area more than once to remove all residue.

How do I remove dried or old dog pee stains from a mattress?

Dried stains can be more stubborn, but you can still improve them.

  1. Lightly re-dampen the area
    Mist the stained area with cool water. This can help loosen dried urine crystals.

  2. Use the vinegar-and-water solution
    Repeat the vinegar plus water process, letting it sit a bit longer (up to 20 minutes).

  3. Consider a gentle enzyme-based cleaner
    Some people find enzyme-based cleaners formulated for pet stains helpful, as they’re designed to break down urine components. If you use one:

    • Test a small, hidden area of the mattress first.
    • Follow the instructions on the label carefully.
    • Avoid oversaturating the mattress.

  4. Blot, apply baking soda, and vacuum
    Finish with blotting, baking soda, and thorough vacuuming, as with a fresh stain. You may need to repeat the process for older or heavier stains.

How can I dry the mattress safely after cleaning?

Proper drying helps prevent lingering odor and moisture.

  • Increase airflow: Open windows, turn on fans, or use a portable fan near the mattress.
  • Use indirect warmth: If possible, place the mattress where it can dry in a warm, ventilated room. Avoid direct high heat, which can damage some mattress materials.
  • Check for dampness: Press your hand or a dry cloth into the area after several hours. If you still feel moisture, give it more time before remaking the bed.

How do I keep my dog from re-marking the same spot?

Dogs sometimes return to the same area if they can still smell urine. To help prevent that:

  • Clean thoroughly so little to no odor remains.
  • Ventilate well to help odors dissipate.
  • Use a washable, waterproof mattress protector in the future to create a barrier between accidents and your mattress.

Is there anything I should avoid when cleaning dog pee from a mattress?

Yes, a few common mistakes can make things worse:

  • Avoid hot water or steam directly on the mattress. Heat can sometimes “set” odors or stains.
  • Avoid harsh chemicals or bleach, which may damage fabrics or irritate skin.
  • Avoid soaking the mattress with too much solution; deep saturation can lead to slow drying and lingering smells.
