How To Remove a Pee Stain From a Mattress: Step‑by‑Step Guide

If you’re searching for How To Remove a Pee Stain From a Mattress, you’re usually dealing with two problems at once: visible staining and lingering odor. This guide walks you through what to do right away, what to do if the stain is already dry, and how to protect your mattress in the future.

What Happens When Pee Gets on a Mattress?

Urine can soak deep into the mattress, especially in foam and pillow-top styles. If it isn’t cleaned properly, you may notice:

  • Yellow or dark stains
  • A persistent smell, especially in warm or humid rooms
  • Spots that seem to “reappear” after light cleaning

That’s why acting quickly and using the right cleaning steps matters.

How To Remove a Pee Stain From a Mattress (Fresh Stain)

Step 1: Blot, Don’t Rub

Use clean, dry cloths or paper towels to blot up as much liquid as possible. Press firmly, replacing towels as they become damp.

  • ✅ Do: Blot from the outside of the stain toward the center.
  • ❌ Don’t: Rub or scrub. This can push urine deeper into the mattress.

Step 2: Apply a Simple Cleaning Solution

A common, gentle approach is:

  • Cool water
  • A small amount of mild liquid soap or a gentle, fabric-safe cleaner

Lightly mist or dab the solution over the stained area. Avoid soaking the mattress; too much liquid can be hard to dry and may cause odors to linger.

Blot again with a clean cloth to lift out both moisture and pee residue.

Step 3: Use Baking Soda to Deodorize

Sprinkle a generous layer of baking soda over the damp area. Baking soda helps absorb moisture and reduce odor.

  • Leave it on for several hours, ideally overnight.
  • Once completely dry, vacuum the baking soda thoroughly.

How To Remove a Pee Stain From a Mattress (Old or Dried Stain)

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

Step 1: Lightly Re‑Dampen the Area

Use a spray bottle with cool water to lightly moisten the stained spot. This can help loosen dried urine so cleaning agents work better. Do not fully soak the mattress.

Step 2: Use a Gentle Cleaner Suitable for Stains and Odors

Apply a fabric- and mattress-safe cleaner designed for organic stains (such as those from food or bodily fluids). Follow the product’s directions, typically:

  • Spray or dab onto the stain
  • Let it sit for the recommended time
  • Blot with a clean, dry cloth

Repeat if necessary, allowing full drying between treatments to see the true result.

Step 3: Finish With Baking Soda

As with fresh stains, apply baking soda after cleaning:

  • Cover the cleaned area
  • Let it sit for several hours
  • Vacuum thoroughly

This step often helps reduce any remaining odor.

Is It Possible to Remove the Smell Completely?

In many cases, most or all of the smell can be reduced with careful cleaning. However, lingering odor can happen if:

  • The mattress was heavily soaked
  • The stain has been there a long time
  • The urine penetrated deeply into thick layers

If smell persists, some people choose to repeat the cleaning process, focus more on odor-targeting cleaners, or use a mattress protector going forward to prevent further issues.

Can Different Mattress Types Be Cleaned the Same Way?

The basic steps are similar, but with a few considerations:

  • Memory foam or latex: These hold moisture easily, so use minimal liquid and allow extra drying time.
  • Innerspring or hybrid: Surface cleaning is often more straightforward, but urine can still reach deeper layers.
  • Pillow‑tops or thick comfort layers: Spend more time blotting and drying; they can absorb more fluid.

Always check your mattress care tag for any specific cleaning warnings or recommendations.

How Long Will It Take the Mattress to Dry?

Drying time depends on room temperature, ventilation, and how much liquid was used. Common ways to speed things up include:

  • Opening windows or using a fan
  • Placing the mattress in a well-ventilated area
  • Ensuring all baking soda is fully vacuumed once dry

The mattress should feel completely dry to the touch before being covered with bedding again.

How Can I Prevent Future Pee Stains on a Mattress?

While accidents happen, a few habits can make cleanup easier:

  • Use a water-resistant or waterproof mattress protector.
  • Wash bedding promptly after accidents.
  • Address any new stain as soon as you notice it, before it has time to set.

These steps can significantly reduce staining and odors over time.
