How To Get Dog Wee Out Of a Mattress: Simple Steps That Actually Work

If you’re searching for “How To Get Dog Wee Out Of a Mattress”, you’re likely dealing with a fresh accident, a lingering smell, or a mysterious stain. This guide walks you through exactly what to do, using common household products and gentle methods that help protect your mattress.

What’s the best first step when a dog pees on a mattress?

Acting quickly is the most important part of how to get dog wee out of a mattress.

  1. Remove bedding
    Strip sheets, mattress protectors, and any covers and wash them according to their care labels.

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

    • Do not scrub – rubbing pushes urine deeper into the mattress.

  3. Prepare a gentle cleaning solution
    A common DIY option is:

    • 1 part white vinegar
    • 1 part cool water
      Mix in a spray bottle or bowl.

  4. Treat the stained area
    Lightly spray or dab the solution onto the affected area until it’s damp (not soaking). Let it sit for about 10–15 minutes.

  5. Blot again
    Press with clean, dry towels to remove as much moisture as possible.

This first response helps break down the urine and prevents it from setting deeply into the foam or fabric.

How do I remove dog urine odour from a mattress?

Even after cleaning, odour can linger if urine crystals remain. To tackle the smell:

  1. Use baking soda
    Sprinkle a generous layer of dry baking soda over the treated area. This helps absorb moisture and neutralise odours.

  2. Let it sit
    Leave the baking soda on the mattress for at least several hours, or ideally overnight. The longer it sits, the more smell it can absorb.

  3. Vacuum thoroughly
    Use a vacuum cleaner with an upholstery attachment to remove all the baking soda. Go slowly over the area a few times.

  4. Repeat if needed
    For strong odours, you may need to repeat the vinegar-and-water treatment followed by baking soda once more.

If you’re wondering how to get dog wee out of a mattress when the smell just won’t go away, patience and repetition are often needed rather than harsher cleaners.

What if the dog urine stain is old or dried?

Older stains can be more stubborn, but you can still improve them:

1. Rehydrate the stain

Lightly mist the area with the vinegar and water mix again to help loosen dried urine. Avoid over-soaking.

2. Add baking soda on top

While the area is still slightly damp, sprinkle baking soda directly onto it. You might see some fizzing if there’s still urine residue; this is normal.

3. Wait longer

Allow the baking soda to sit 12–24 hours if possible, then vacuum well.

4. Set expectations

  • Very old or deep stains may not disappear completely.
  • However, smell and appearance often improve significantly with repeated gentle treatments.

Is it safe to use strong cleaners or steam on a mattress?

When thinking about how to get dog wee out of a mattress, it can be tempting to reach for the strongest products available. There are some important cautions:

  • Avoid bleach or harsh chemicals
    These can damage mattress fabrics, break down foams, or leave strong chemical odours.

  • Be careful with steam cleaners
    High heat and moisture can drive urine deeper into the mattress and make drying harder. Trapped moisture can lead to long-term issues.

  • Use limited liquid
    Mattresses are thick and slow to dry. Too much liquid makes full drying difficult, which is why spraying lightly and blotting thoroughly is recommended.

How can I dry the mattress properly after cleaning?

Good drying is just as important as cleaning:

  • Increase airflow
    Open windows, turn on fans, or use a portable fan aimed at the mattress surface.

  • Stand the mattress up if possible
    Leaning it safely against a wall can help air circulate around it.

  • Allow plenty of time
    Make sure the mattress is completely dry before putting on bedding or sleeping on it again. This can take several hours or more, depending on the amount of moisture and room conditions.

  • Check with your hand
    Press with your palm and feel for any cool or damp spots. If it feels cool compared to the rest of the mattress, it may still be slightly damp.

How do I stop repeat accidents from ruining the mattress?

If your dog has had one accident, they may return to the same spot. Some simple precautions can help:

  • Use a waterproof mattress protector
    This adds a barrier between your mattress and any future spills or accidents.

  • Wash bedding promptly
    Cleaning sheets and protectors soon after an accident helps remove lingering odours that might attract repeat marking.

  • Limit access during house-training
    Some people choose to keep pets off the bed while they work on training and routines.

These steps don’t just help with how to get dog wee out of a mattress now; they also make any future clean-ups much easier.
