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

If you’re searching for “How To Clean Pee Off Of a Mattress,” you’re likely dealing with a fresh accident or a lingering stain. This guide walks you through what to do right now, how to handle dried stains, and how to reduce odors so your mattress stays usable and comfortable.

What Happens When Pee Gets On a Mattress?

Urine can soak deep into mattress layers. If it isn’t cleaned properly, you may notice:

  • Yellow or darker stains
  • A lingering ammonia-like odor
  • A damp or “stale” feeling in that area of the bed

Since most mattresses cannot be fully washed, surface cleaning and spot treatment are usually the best options. Acting quickly helps prevent deeper staining and stronger smell.

How To Clean Pee Off Of a Mattress (Fresh Accidents)

Step 1: 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.

Step 2: Apply a Mild Cleaning Solution

A common approach is to use:

  • Cool water
  • A small amount of gentle liquid soap or mild detergent

Lightly dampen (do not soak) a clean cloth with the solution and dab the affected area. The goal is to lift urine from the fabric, not saturate the mattress.

Step 3: Rinse Lightly

Use another cloth dampened with plain water to blot away any soap residue. Too much water can keep the mattress wet for longer, so use it sparingly.

Step 4: Absorb Moisture and Dry Thoroughly

Blot again with dry towels. Then:

  • Allow plenty of air circulation
  • If available, use a fan to speed up drying
  • Make sure the mattress is completely dry before putting bedding back on

Proper drying helps reduce odor and the chance of mildew forming in the damp area.

How To Clean Pee Off Of a Mattress If It’s Already Dried

Dried urine can leave a stubborn stain and odor. The approach is similar, but may need more time and repetition.

Step 1: Lightly Rehydrate the Stain

Use a cloth slightly dampened with cool water to moisten the stained area. This can help loosen dried residue.

Step 2: Use a Gentle Cleaning or Enzymatic Cleaner

Many people find that enzyme-based cleaners designed for organic stains can help break down urine residues. Follow the instructions provided for the product you choose (spraying lightly and letting it sit for the recommended time).

Step 3: Blot and Air-Dry

After treating:

  • Blot with dry towels
  • Let the mattress air-dry completely
  • Re-treat if faint odor or discoloration remains

Some older stains may never disappear entirely, but they can often be significantly lightened and deodorized.

How Do I Get Rid of Pee Smell From a Mattress?

Odor can linger even after visible stains are gone. Some commonly used approaches include:

  • Thorough cleaning first, as above
  • Allowing plenty of fresh air and time to dry
  • Lightly sprinkling a deodorizing powder over the area once dry, then vacuuming it up after it sits for several hours

The key is removing as much urine residue as possible, not just masking the smell.

Is It Safe To Sleep On the Mattress After Cleaning?

Once the mattress is completely dry and there is no visible dampness:

  • It is generally considered fine to put clean bedding back on
  • Some people prefer to wait a bit longer if a slight odor remains, allowing more airing out time

If the mattress still feels damp or smells strongly, give it more time to dry and, if needed, repeat cleaning.

How Can I Prevent Future Pee Stains on My Mattress?

Accidents happen, especially in homes with children, pets, or anyone managing incontinence. To make future cleanups easier:

  • Use a water-resistant or waterproof mattress protector
  • Check the bed quickly after any suspected accident so you can treat fresh spills right away
  • Keep basic cleaning supplies (towels, mild cleaner) nearby for quick response

A protector can act as a barrier, so you only need to clean the cover, not the mattress itself.
