How To Clean a Pee Stain From a Mattress: Step-by-Step FAQ Guide

If you’re searching for “How To Clean a Pee Stain From a Mattress,” you’re likely dealing with a fresh accident or an old, lingering stain. This guide walks you through what to do right away, how to handle dried stains and odors, and what to avoid so you don’t damage your mattress.

What should I do first when pee gets on my mattress?

Act quickly. The faster you respond, the more likely you’ll prevent a permanent stain or odor.

  1. Remove bedding
    Strip sheets, mattress protectors, and blankets so you can see the affected area clearly.

  2. Blot, don’t rub
    Use a clean, dry towel or paper towels to gently press on the wet spot.

    • Do not scrub. Scrubbing can push moisture deeper into the mattress.
  3. Keep liquids minimal at first
    Before using any cleaner, remove as much urine as possible with dry towels.

How To Clean a Pee Stain From a Mattress (Fresh Stains)

Here’s a simple method using common household ingredients:

  1. Mix a mild cleaning solution
    In a spray bottle, combine:

    • About 1 part gentle liquid detergent (or mild dish soap)
    • 4–5 parts cool water
  2. Lightly spray the stain

    • Avoid soaking the mattress.
    • Focus on the stained area and slightly beyond, since liquid may have spread.
  3. Blot again

    • Use a clean, dry cloth to press and lift the solution and urine out of the mattress.
    • Repeat spraying and blotting until the stain lightens.
  4. Rinse carefully

    • Lightly mist with plain water and blot again to remove soapy residue.
    • Too much water can make drying harder and may cause odors.
  5. Dry thoroughly

    • Let the mattress air dry completely.
    • If possible, speed things up with a fan or open window.
    • Only put bedding back on when the mattress feels fully dry to the touch.

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

Older stains often need a little extra help, especially with odor.

  1. Rehydrate the stain
    Lightly spray the area with cool water. This can help loosen dried residue.

  2. Use a gentle cleaning solution
    Apply the same mild soapy water mix and blot repeatedly.

  3. Consider using baking soda for odor

    • Once you’ve cleaned the area and it is damp, sprinkle baking soda generously over the spot.
    • Leave it on for several hours, or overnight if possible.
    • Vacuum thoroughly to remove all powder.

If the stain is still visible after this, you can repeat the process. Some older stains may never disappear completely but can often be lightened and deodorized significantly.

How can I get rid of lingering pee smell?

Even after cleaning, odor can remain in the mattress. Here are common approaches:

  • Baking soda

    • Sprinkle a thick layer over the cleaned, dry area.
    • Let it sit for 8–24 hours.
    • Vacuum it up thoroughly.
  • Good airflow

    • If practical, place the mattress where it can get fresh air.
    • Use fans to improve drying and reduce musty smells.
  • Repeat if needed

    • Sometimes odors improve gradually with more than one baking soda treatment.

What should I avoid when cleaning a pee stain?

Certain mistakes can make the stain or smell worse:

  • Soaking the mattress
    Too much liquid can sink deep and be hard to dry, leading to persistent odors.

  • Scrubbing aggressively
    This can push urine deeper and damage the fabric or surface.

  • Using harsh chemicals
    Strong cleaners can discolor or weaken mattress materials and may leave their own strong odor behind.

  • Skipping the drying step
    A mattress that stays damp can smell musty and feel uncomfortable.

How can I prevent future pee stains on a mattress?

While accidents are sometimes unavoidable, you can make cleanup easier:

  • Use a waterproof mattress protector
    These sit between the mattress and sheets and can help keep liquids from soaking into the mattress itself.

  • Layer bedding
    Some people use a mattress protector plus an easily washable pad under the fitted sheet for added peace of mind.

  • Clean accidents promptly
    The sooner you act, the less likely the stain and odor will set.

Is it safe to sleep on the mattress after cleaning?

Once the mattress is completely dry, it is generally fine to make the bed and use it again. Make sure:

  • There are no damp spots when you press down with your hand.
  • There is no strong cleaner residue or noticeable film on the surface.
