How To Clean Mattress After Pee: Simple Steps to Remove Odor and Stains

If you’re searching for “How To Clean Mattress After Pee”, you’re likely dealing with a fresh accident or an old urine stain. The good news is that you can usually clean it at home with basic supplies and a bit of patience. This guide answers the most common questions about cleaning pee from a mattress and keeping it fresh.

Why Cleaning Urine From a Mattress Matters

Urine on a mattress is more than just an inconvenience. It can cause:

  • Lingering odors that are hard to ignore
  • Visible stains that become darker over time
  • Moisture trapped inside the mattress, which can shorten its usable life

Acting promptly and using the right method can help reduce staining, neutralize odors, and protect your mattress.

How To Clean Mattress After Pee: Step-by-Step for Fresh Accidents

What should I do first when someone pees on the mattress?

  1. Remove bedding immediately
    Strip sheets, mattress protector, and any blankets. Wash these separately according to their care labels.

  2. Blot, don’t rub
    Use clean, dry towels or paper towels to blot up as much liquid as possible. Press firmly, but avoid scrubbing, which can push urine deeper into the mattress.

  3. Apply a gentle cleaning solution
    Many people find a mix of cool water and mild dish soap or a water and white vinegar solution helpful for cleaning urine. Lightly spray or dab the area—do not soak the mattress.

  4. Blot again
    Use fresh towels to absorb excess moisture from the cleaning solution. The goal is to leave the mattress only slightly damp, not wet.

  5. Use an odor-neutralizing powder
    Sprinkle baking soda generously over the damp area. Baking soda is commonly used to help absorb moisture and reduce odor.

  6. Let it sit, then vacuum
    Allow the baking soda to sit for several hours or overnight, then vacuum it up using a clean upholstery attachment.

How do I clean dried or old pee stains from a mattress?

Dried urine can be more stubborn, but you can still improve stains and smells.

Steps for older stains

  1. Lightly re-dampen the area
    Use a spray bottle with a small amount of water or a water-and-vinegar mix to re-moisten the stain. This can help loosen dried residue.

  2. Gently work in a mild cleaner
    Use a soft cloth and a gentle cleaning solution, such as diluted dish soap. Dab, don’t rub aggressively, to avoid damaging the mattress surface.

  3. Blot thoroughly
    Press with dry towels to pull out as much liquid as possible.

  4. Apply baking soda
    Cover the area with baking soda and leave it for several hours to help with odor and remaining moisture.

  5. Vacuum and repeat if needed
    Vacuum the baking soda, then check the stain. Some old stains may not disappear completely, but repeated gentle treatments can often reduce their appearance and smell.

Is it safe to use strong cleaners or bleach on a mattress?

Most mattress care guidelines recommend avoiding harsh chemicals like bleach or highly concentrated cleaners. These can:

  • Discolor the mattress fabric
  • Leave strong chemical odors
  • Potentially damage materials inside the mattress

For most situations, mild cleaners and simple household ingredients are a safer choice.

How can I remove the urine smell completely?

Urine odor can linger even after the stain looks lighter. To help with smell:

  • Use enough baking soda to fully cover the affected area
  • Let it sit longer—often overnight or even a full day for deeper odors
  • Repeat the process if needed

For severe or persistent smells, some people choose specialized upholstery or mattress cleaners that are designed to handle strong odors. Always spot-test a small, hidden area first.

Can I clean pee from any type of mattress?

Different mattress types (foam, hybrid, innerspring, latex) can respond differently to moisture. In general:

  • Avoid soaking any mattress. Excess water can be hard to remove from deep layers.
  • Spot-clean only. Focus on the affected area rather than the entire surface.
  • Check the care tag. Many mattresses include basic do’s and don’ts for cleaning.

If the mattress has a removable cover with care instructions, follow those for the cover, but still be cautious with the inner layers.

How can I dry the mattress after cleaning?

Drying is just as important as cleaning when learning How To Clean Mattress After Pee:

  • Increase airflow by opening windows or using a fan.
  • Use a cool or low-heat setting if using a hairdryer, and keep it moving to avoid heat damage.
  • Allow extra time—a mattress can feel dry to the touch while still slightly damp inside.

Only put bedding back on once the mattress is fully dry.

How do I prevent future pee stains on my mattress?

Accidents happen, especially with young children or pets. To protect your mattress:

  • Use a water-resistant or waterproof mattress protector
  • Wash bedding regularly to help control odors
  • Address accidents as soon as you notice them to make cleanup easier

These steps can help keep your mattress cleaner and easier to maintain over time.
