How To Clean Pee Off Of Mattress: Simple Steps That Actually Work

If you’re searching for “How To Clean Pee Off Of Mattress”, you’re likely dealing with a fresh accident or an old stain and want it gone fast—along with any lingering smell. This guide walks you through what to do, step by step, using common household supplies and gentle methods that are safe for most mattresses.

Why Does Pee Stick Around in a Mattress?

Mattresses are thick, absorbent, and hard to fully rinse. Urine soaks into the layers, which can lead to:

  • Visible yellow stains
  • Unpleasant odors
  • A general feeling that the bed isn’t truly clean

Cleaning pee off a mattress takes more than just wiping the surface. You’ll want to blot, break down the urine, and draw moisture back out without soaking the mattress.

How To Clean Pee Off Of Mattress (Fresh Stain)

Step 1: Act Fast and Blot, Don’t Scrub

  1. Strip all bedding and wash it separately.
  2. Use clean, dry towels or paper towels to press firmly onto the wet area.
  3. Keep blotting with new towels until you’ve absorbed as much moisture as possible.

Avoid scrubbing—this can push urine deeper into the mattress fibers.

Step 2: Apply a Gentle Cleaning Solution

A simple option many people use:

  • Mix equal parts white vinegar and water in a spray bottle.

Then:

  1. Lightly spray the stained area.
  2. Let it sit for 5–10 minutes to help break down the urine.
  3. Blot again with clean towels to remove excess moisture.

Vinegar has a noticeable smell at first, but it usually fades as it dries.

Step 3: Use Baking Soda to Draw Out Moisture and Odor

  1. Sprinkle a thick, even layer of baking soda over the damp area.
  2. Gently spread it so it covers slightly beyond the stain.
  3. Leave it on for at least 8 hours, or overnight if possible.

Baking soda helps absorb remaining moisture and neutralize lingering odors.

Step 4: Vacuum Thoroughly

Once the baking soda is completely dry:

  1. Use a vacuum with an upholstery attachment.
  2. Slowly vacuum all the baking soda from the mattress surface.
  3. Check for any remaining odor or faint staining.

If some smell remains, you can repeat the process once more.

How Do You Clean Dried or Old Pee Stains?

Old stains are usually more stubborn, but you can still improve them.

Step 1: Lightly Re-Dampen the Area

  1. Mix a small amount of mild dish soap in cool water.
  2. Lightly dampen (do not soak) the stained area with a cloth.
  3. Blot to loosen and lift some of the dried residue.

Step 2: Use Vinegar Solution Again

Follow the same vinegar and water spray method:

  • Spray lightly
  • Let sit for a few minutes
  • Blot thoroughly

Then apply baking soda and vacuum once dried. You may need multiple rounds for older stains, with drying time between each attempt.

Is It Safe to Use Enzyme Cleaners on a Mattress?

Many people use enzyme-based cleaners made for pet or household stains to help break down urine. In general:

  • Check that the cleaner is labeled for use on fabrics or upholstery.
  • Patch-test on a hidden area of your mattress first.
  • Follow the instructions carefully and avoid oversaturating.

Enzyme cleaners can be especially helpful for older or strong-smelling stains, but they still need proper blotting and drying.

How Can I Remove the Smell Without Damaging the Mattress?

To reduce odor without harsh treatment:

  • Keep using baking soda as your main deodorizer.
  • Air out the room and, if possible, the mattress itself.
  • Avoid heavy perfumes or sprays directly on the mattress; they may mask, not remove, the odor.

If the smell lingers after several careful cleanings, the urine may have penetrated deeper layers that are harder to reach.

Can Any Mattress Type Be Cleaned This Way?

Most standard mattresses—such as foam, hybrid, or innerspring—tolerate light, surface-level cleaning with minimal moisture. Still, keep in mind:

  • Do not soak memory foam or pillow-top mattresses. They hold water and dry slowly.
  • Always let the mattress dry completely before putting bedding back on.
  • If your mattress has a removable cover, check the care label before washing or treating it.

How Do I Prevent Future Pee Stains on My Mattress?

Once you’ve handled the current accident, prevention makes future cleanups much easier:

  • Use a waterproof mattress protector to create a barrier.
  • Add a washable mattress pad or fitted cover on top for extra protection.
  • Wash bedding regularly to keep the sleep surface fresh.

These layers help keep any future spills or accidents on the surface, instead of soaking into the mattress core.
