How To Get Dog Pee Out Of a Mattress: Step‑by‑Step FAQ Guide

If you’re searching for “How To Get Dog Pee Out Of a Mattress,” you’re likely dealing with a fresh accident or an old, lingering stain. This guide walks through what to do right away, how to treat dried urine, and how to handle odor so your mattress stays usable and comfortable.

Why Is Dog Urine on a Mattress So Hard to Remove?

Dog urine is more than just liquid on fabric. It contains urea, salts, and other compounds that can:

  • Soak deep into foam and padding
  • Leave behind yellow stains
  • Cause persistent odor, especially in warm or humid rooms

A quick surface wipe usually isn’t enough. To truly handle how to get dog pee out of a mattress, you need to blot, break down the urine, and remove as much moisture as possible from deeper layers.

What Should I Do Immediately After My Dog Pees on the Mattress?

Step 1: Blot, Don’t Rub

Use clean, absorbent towels or paper towels to blot up as much urine as possible.

  • Press firmly to pull moisture out of the mattress
  • Replace towels as they become saturated
  • Avoid rubbing, which can push urine deeper and spread the stain

Step 2: Mix a Simple Cleaning Solution

Many people use a mild, homemade solution to start cleaning:

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

Vinegar helps neutralize some of the compounds in urine and reduces odor.

Lightly spray or dab this mixture onto the stained area. The mattress should feel damp, not soaking wet, to avoid mold or slow drying.

Step 3: Blot Again

After applying the solution, blot thoroughly again. Your goal is to lift both the cleaning solution and remaining urine out of the mattress.

How Do I Remove Dog Pee Odor From a Mattress?

Even if the stain fades, odor can linger. Here’s how to target smell:

Use Baking Soda for Odor Control

Sprinkle a generous layer of baking soda over the cleaned, slightly damp area.

  • Gently work it in with your hand
  • Leave it on for several hours, or ideally overnight
  • Vacuum thoroughly using an upholstery attachment

Baking soda can help absorb lingering moisture and reduce odor. Some people repeat this step if any smell remains.

How Do I Get Dried Dog Pee Out of a Mattress?

When urine has already dried, you’re dealing with set-in stains and more persistent odor.

Step 1: Re-Dampen the Area

Lightly spray the dry stain with the vinegar-and-water solution. This helps loosen dried urine crystals from the mattress fibers.

Step 2: Treat With an Enzymatic Cleaner (Optional)

Many pet owners use a pet-safe enzymatic cleaner designed for urine. These products are made to help break down organic compounds. Follow the instructions on the label carefully, including:

  • How heavily to apply
  • How long to let it sit
  • Whether to blot or let air dry

Step 3: Use Baking Soda Again

After treatment, apply baking soda to the area once more and let it sit before vacuuming.

Repeated cycles of treat → blot → baking soda → vacuum are often needed for older, deeper stains.

Can Dog Pee Permanently Damage a Mattress?

Dog urine can cause:

  • Permanent discoloration (yellow or brown spots)
  • Lingering odor if not fully cleaned
  • A musty smell if the mattress stays damp too long

You may not always remove every trace of staining, especially on light fabrics, but prompt and thorough cleaning usually improves both appearance and smell significantly.

If the mattress feels soggy, misshapen, or has a strong musty odor even after cleaning and drying, it may be more difficult to fully restore.

How Can I Dry the Mattress Safely After Cleaning?

Proper drying is key when you’re learning how to get dog pee out of a mattress without causing new problems.

  • Increase airflow: Open windows, use fans, or place the mattress in a well‑ventilated space
  • Use indirect heat only: Gentle warmth (like room heaters) can help, but avoid direct high heat that may damage foam
  • Check both sides: If the liquid soaked through, stand the mattress on its side so air can reach more surfaces

The mattress should feel completely dry to the touch, not cool or slightly damp, before putting sheets back on.

How Do I Prevent Future Dog Pee Accidents on My Mattress?

While accidents happen, a few habits can make clean‑up easier next time:

  • Use a waterproof mattress protector under your fitted sheet
  • Add an extra washable mattress pad for another layer of defense
  • Keep spare bedding sets and covers on hand for quick changes
  • Consider limiting access to the bed if accidents are frequent

These steps won’t stop accidents, but they can keep urine from soaking into the mattress core, which is the hardest part to clean.
