How To Get Rid Of Dog Urine Smell On Mattress: Step‑By‑Step FAQ Guide

If you’re searching for “How To Get Rid Of Dog Urine Smell On Mattress,” you probably have a fresh accident, a lingering smell, or both. This guide answers the most common questions about cleaning dog urine from a mattress and removing that stubborn odor for good.

What’s the best way to clean fresh dog urine from a mattress?

Acting quickly is the easiest way to prevent stains and smells from setting in.

Step‑by‑step for fresh accidents:

  1. Blot, don’t rub
    Use paper towels or a clean cloth to press firmly into the wet area. Soak up as much liquid as possible. Avoid rubbing, which can push urine deeper into the mattress.

  2. Apply a gentle cleaning solution
    A common DIY option is mild dish soap mixed with cool water. Lightly dampen (do not soak) a cloth and blot the area.

  3. Use an enzyme-based cleaner (if available)
    Cleaners designed for pet stains can help break down urine components that cause lingering odor. Follow the label directions and avoid over-saturating the mattress.

  4. Blot again and remove excess moisture
    Press with dry towels to pull out moisture. You can stand or kneel on the towels to apply more pressure.

  5. Let the mattress dry completely
    Allow plenty of time to air out. Good airflow, a fan, or open windows can speed this up. Ensure the mattress is fully dry before adding bedding.

How do I get rid of a lingering dog urine smell on my mattress?

When the accident is older, odor removal becomes the main issue. Here’s How To Get Rid Of Dog Urine Smell On Mattress when the smell won’t go away:

  1. Re-clean the area
    Even if it looks clean, dried urine can remain in the foam or fabric. Lightly re-dampen the area with a water and mild detergent mix and blot again.

  2. Use an odor-focused cleaner
    Enzyme-based cleaners are often used for breaking down odor-causing residues in pet urine. Apply according to the label, then blot and allow to dry fully.

  3. Deodorize with baking soda
    When the area is just slightly damp, sprinkle a generous layer of baking soda over the spot. Gently press it into the surface and let it sit for several hours or overnight.

  4. Vacuum thoroughly
    Once dry, vacuum the baking soda from the mattress. This helps lift out both powder and lingering odor.

If smell remains, repeat the baking soda step once more. Some mattresses and deeper stains may need more than one treatment.

Which household ingredients can help with dog urine odor?

Several common household items are often used to reduce odor, but they should be used carefully on mattresses.

  • Baking soda – Frequently used for absorbing smells. Safe for most mattress fabrics when applied dry and vacuumed thoroughly.
  • Mild dish soap – Mixed with water, it helps loosen and clean surface residue.
  • White vinegar solution – Some people use a diluted vinegar and water mix to help with deodorizing. On a mattress, it should be used sparingly to avoid over-wetting, and always tested on a small, hidden area first.

Avoid harsh chemicals or heavy fragrances that may damage mattress materials or leave their own persistent smell.

How can I prevent dog urine smells from coming back?

A few simple habits can help keep the smell from returning or reappearing:

  • Clean accidents as soon as possible to stop urine from soaking deeper.
  • Use a waterproof mattress protector to create a barrier between your dog and the mattress.
  • Air out your mattress periodically by stripping the bed and letting it breathe.
  • Keep bedding clean so odors don’t transfer back onto the mattress.

These steps won’t stop accidents, but they can limit how much reaches the mattress and how long any odor lingers.

When should I consider that the smell might be permanent?

Some mattresses hold onto odors more than others, especially if:

  • The mattress has multiple, old pet accidents.
  • The urine has soaked deep into thick foam layers.
  • The mattress was never dried fully after cleaning.

If you’ve tried cleaning, deodorizing, and repeating the process and the smell is still strong, it may be very difficult to remove entirely. In these situations, you can still reduce the odor, but complete removal might not be realistic.

Is it safe for my dog to keep sleeping on the mattress after an accident?

From a cleaning perspective, once the urine is removed, the area is dry, and any cleaners are fully gone, it is generally similar to any other cleaned surface in your home. If you have any concerns about specific cleaning products or your dog’s sensitivities, checking labels and choosing gentle, pet-friendly options may be helpful.
