How To Clean Pet Urine From Mattress: Simple Steps That Actually Work

If you’re searching for How To Clean Pet Urine From Mattress, you’re likely dealing with a fresh accident or a lingering smell you can’t get rid of. This guide walks through exactly what to do, which products to avoid, and how to handle both new and old stains so your mattress stays as clean and comfortable as possible.

Why Pet Urine on a Mattress Needs Special Care

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

  • Soak deep into the mattress layers, making it hard to reach.
  • Leave behind stains, odors, and residue if not treated correctly.
  • Encourage pets to re-mark the same area if any scent remains.

Because most mattresses can’t be machine washed, learning how to clean pet urine from mattress surfaces safely is essential for keeping your bed fresh and usable.

What Should I Do First When My Pet Pees on the Mattress?

Step 1: Act quickly and blot, don’t rub

  1. Remove bedding right away and set it aside to wash separately.
  2. Use clean, dry towels or paper towels to blot up as much urine as possible.
  3. Press firmly to absorb moisture, but do not scrub, which can spread the stain deeper.

The goal is to lift liquid out of the mattress, not push it further in.

Step 2: Apply a gentle cleaning solution

For most fresh pet urine stains, a simple solution can help:

  • Mix equal parts cool water and white vinegar in a spray bottle or bowl.
  • Lightly spray or dab the solution onto the stained area.
  • Let it sit for 5–10 minutes to help break down the urine.
  • Blot again with clean towels until the area feels only slightly damp.

Vinegar helps neutralize odors and reduce visible staining without harsh chemicals.

Can I Use Baking Soda to Remove Pet Urine Smell?

Yes. Baking soda is commonly used to absorb odors from pet urine. After blotting and treating the area:

  1. Sprinkle a generous layer of dry baking soda over the damp spot.
  2. Gently work it in with your fingertips or a soft brush.
  3. Leave it for several hours, or overnight if possible.
  4. Vacuum thoroughly using an upholstery attachment.

If odor lingers, you can repeat the baking soda step. This method is often used as a final “freshening” step once most of the moisture has been removed.

How To Clean Pet Urine From Mattress When the Stain Is Old or Dried

Dried pet urine can be tougher because it has had time to set into the fabric and foam. You can still try the same basic process with some adjustments:

  1. Lightly mist the area with plain water first. This can help rehydrate the dried urine.
  2. Apply the vinegar and water solution as described earlier.
  3. Let it sit a bit longer (around 10–15 minutes), then blot thoroughly.
  4. Follow up with baking soda once the area is only lightly damp.

Sometimes, older stains may leave a faint discoloration even after cleaning. The main goal is to neutralize odor and remove residue so the mattress remains comfortable and usable.

Which Cleaners Should I Avoid on a Mattress?

When thinking about how to clean pet urine from mattress surfaces, it’s important to know what not to use:

  • Avoid harsh bleach or strong chemicals that can damage fabric or irritate skin.
  • Be cautious with steam cleaners, which can push moisture deeper and may be hard to dry out.
  • Use minimal liquid overall; soaking a mattress can lead to slow drying and potential odor issues.

Whenever possible, test any new cleaning solution on a small, hidden area of the mattress first.

How Do I Dry the Mattress After Cleaning Pet Urine?

Drying is just as important as cleaning. To help your mattress dry properly:

  • Open windows or use a fan to improve air circulation.
  • If possible, stand the mattress on its side to allow air to reach more surfaces.
  • Avoid remaking the bed or covering the area until it is fully dry to the touch.

Good drying helps prevent lingering smells and keeps the mattress more comfortable.

Will the Smell Encourage My Pet to Pee There Again?

Many pet owners notice that if any urine odor remains, pets may return to the same spot. Thorough cleaning and odor removal help reduce this risk. For some households, using a protective, washable mattress cover can also make future accidents easier to manage.
