How To Remove Pee Stains From Mattress: Step‑By‑Step Guide That Actually Helps

If you’re searching for how to remove pee stains from mattress, you’re likely dealing with a fresh accident or an older, stubborn stain. This guide walks you through what works, what to avoid, and how to reduce both stains and lingering odors without damaging your mattress.

What Happens When Pee Gets On a Mattress?

Urine can soak deep into the mattress layers. If it dries, it can leave behind:

  • Yellow stains
  • Lingering odor
  • A slightly stiff or rough patch on the fabric

Because most mattresses can’t go in a washing machine, learning how to remove pee stains from mattress surfaces safely is important for keeping your bed clean and comfortable.

How To Remove Fresh Pee Stains From a Mattress

Acting quickly usually gives the best results.

1. Blot, Don’t Rub

  • Use a clean, dry cloth or paper towels.
  • Press firmly to absorb as much liquid as possible.
  • Avoid scrubbing, which can push urine deeper into the mattress.

2. Apply a Gentle Cleaning Solution

A simple home mixture can be helpful:

  • Mix a small amount of mild liquid soap with cool water, or
  • Use a vinegar-and-water mix (about equal parts) if the mattress care instructions allow for it.

Lightly spray or dab the solution on the stained area, then blot again with a clean cloth. The goal is to dampen the stain, not soak the mattress.

3. Deodorize With Baking Soda

Sprinkle baking soda over the damp area:

  • Let it sit for several hours, or ideally overnight.
  • Baking soda can help absorb moisture and some odor.

Once dry, vacuum the baking soda thoroughly using an upholstery attachment if available.

How To Remove Dried or Old Pee Stains From a Mattress

Older stains are usually more stubborn, but you can often improve them significantly.

1. Rehydrate the Stain Slightly

Lightly mist the area with water or a mild cleaning solution to soften the dried residue. Do not oversaturate.

2. Use a Targeted Cleaning Approach

For older stains:

  • Gently dab with a cloth and your chosen solution.
  • Work from the outside of the stain toward the center to avoid spreading it.

You might need to repeat this process several times for deeper or more visible stains.

3. Let It Dry Completely

After cleaning:

  • Blot away as much moisture as possible.
  • Allow the mattress to air dry fully before putting sheets back on.
    If possible, increase airflow with a fan and open windows.

Is It Possible To Remove Pee Smell Completely?

Odor often lingers longer than the visible stain. Some key points:

  • Baking soda is a gentle, commonly used option for mild odor.
  • Multiple cleaning rounds may be needed for strong or long-standing smells.
  • Allowing enough drying time is essential. A damp mattress can hold onto odor.

If a smell remains after trying typical home methods several times, it may simply be very deeply absorbed, and only partial improvement is realistic.

Can You Use Bleach or Harsh Chemicals?

Many mattresses are sensitive to strong chemicals. These can:

  • Discolor fabrics
  • Weaken materials
  • Leave strong residual odors

Unless your specific mattress care tag clearly states otherwise, it’s generally safer to avoid bleach and highly concentrated cleaners directly on the mattress.

How To Prevent Future Pee Stains on Your Mattress

Accidents happen, but you can limit the impact.

  • Use a waterproof mattress protector to create a barrier between spills and the mattress.
  • If an accident happens, strip the bedding immediately and follow the fresh-stain steps above.
  • Check the area again after drying to see if any faint staining remains, and repeat if needed.
