How Do You Clean Dog Urine Out Of a Mattress? Step‑by‑Step FAQ Guide

If you’re searching “How Do You Clean Dog Urine Out Of a Mattress”, you’re probably dealing with a fresh accident or a lingering smell you just can’t ignore. This guide walks you through what to do right now, how to remove stains and odours, and when it might be time to consider deeper cleaning.

Why Dog Urine on a Mattress Needs Special Attention

Dog urine is more than just a wet spot. It can:

Soak deeply into foam and fabric, making it hard to reach.
Leave yellow stains if not treated quickly.
Cause lingering odours as it dries and breaks down.

Because a mattress can’t go in the washing machine, the cleaning steps for how do you clean dog urine out of a mattress are all about absorbing, neutralizing, and thoroughly drying the area without over‑saturating it.

What Should You Do First When Your Dog Pees on the Bed?

Step 1: Act Quickly and Blot, Don’t Rub

As soon as you notice the urine:

Strip the bedding and set it aside for separate washing.
Use clean, dry towels or paper towels to blot the area firmly.
Keep blotting with fresh sections until little or no moisture transfers.

Rubbing can push urine deeper into the mattress layers and spread the stain.

How Do You Clean Dog Urine Out Of a Mattress: Simple Home Method

Here’s a commonly used, home-friendly approach using items many people already have.

Step 2: Apply a Mild Cleaning Solution

You can make a basic cleaning mix:

Cool or lukewarm water
A small amount of gentle, non‑bleach dish soap or mild detergent

Lightly dampen (do not soak) a clean cloth with the solution and dab the stained area. The goal is to lift urine from the surface, not to flood the mattress.

Avoid harsh chemicals or anything with bleach, as these may damage fabrics or discolor the mattress.

Step 3: Use Vinegar to Help Neutralize Odour

Many people find a simple vinegar mix helpful for odours:

Mix equal parts white vinegar and water in a spray bottle or bowl.
Lightly spray or dab the affected area; don’t oversaturate.
Let it sit for about 5–10 minutes.

Vinegar has a strong smell at first, but it usually fades as it dries. It can help break down odour‑causing residue left behind by urine.

Step 4: Apply Baking Soda for Odour and Moisture

While the spot is still lightly damp from cleaning:

Sprinkle a generous layer of baking soda directly over the area.
Gently spread it to cover slightly beyond the stain.

Baking soda can absorb moisture and odours from the surface and upper layers of the mattress.

Leave it on for several hours, or ideally overnight, so it has time to work.

Step 5: Vacuum Thoroughly

Once the baking soda is completely dry and clumpy:

Use a vacuum with an upholstery attachment.
Slowly vacuum up all visible baking soda.
Check for remaining odour or dampness. Repeat the baking soda step if needed.

What If the Urine Stain Is Old or Already Dry?

Old dog urine stains can be more stubborn. You can still follow the same general steps:

Lightly re‑dampen the stained area with a vinegar‑and‑water mix.
Let it sit briefly to help soften dried residue.
Blot, then apply baking soda as above.
Vacuum when fully dry.

Severe or long‑standing stains may not disappear completely, but odours and visible discoloration often improve with patient, repeated treatments.

How Do You Get Rid of the Smell Completely?

Dog urine odour lingers because it can seep into deeper layers. To improve results:

Make sure the mattress dries fully between cleaning attempts.
Use good airflow: open windows, use a fan, or place the mattress where air can circulate.
Avoid covering the mattress with sheets or protectors until it is completely dry.

If the smell is still strong after several careful cleanings, some people choose:

A professional upholstery or mattress cleaning service that uses deeper extraction methods.

How Can You Dry the Mattress Safely?

Drying is essential to prevent musty smells.

Air dry in a well‑ventilated room.
Use a fan pointed at the damp area.
If safe for your mattress, indirect sunlight can help with both drying and slight odour reduction.

Avoid high heat from hair dryers or heaters pointed close to the mattress, as this can damage materials or trap odours if the inside stays damp.

How Do You Prevent Future Dog Urine Accidents on a Mattress?

Once you’ve learned how do you clean dog urine out of a mattress, it’s natural to want to stop it from happening again:

Use a waterproof mattress protector to create a barrier between your dog and the mattress.
Place a washable cover or blanket over your usual bedding when your dog is on the bed.
Ensure frequent bathroom breaks and consistent routines for your dog.
Consider limiting access to the bed when you’re not present, especially with puppies or older dogs.

Prevention makes any future cleanup far easier and helps your mattress last longer.
