How To Get Urine Stain Off Mattress: Simple Steps That Actually Work

If you’re searching for “How To Get Urine Stain Off Mattress”, you’re likely dealing with a fresh accident or discovering an older, yellow stain and lingering odor. This guide walks you through practical, at-home methods to clean urine from a mattress, protect the materials inside, and reduce smells as much as possible.

What Happens When Urine Gets on a Mattress?

Urine can soak quickly through sheets and into the mattress comfort layers. If it sits too long, it can cause:

  • Yellow or dark stains
  • Persistent odor
  • A damp spot that takes a long time to dry

Because most mattresses can’t be machine-washed, learning how to get urine stain off mattress surfaces safely is important to avoid long-term discoloration and smells.

How To Get Urine Stain Off Mattress: Step-by-Step

Step 1: Act Fast and Blot (Don’t Rub)

If the stain is fresh:

  1. Strip all bedding.
  2. Use clean, absorbent towels or paper towels to blot the wet area.
  3. Press firmly to pull moisture up out of the mattress.
  4. Avoid scrubbing, which can push urine deeper into the foam or padding.

The more liquid you remove early, the easier the rest of the process will be.

Step 2: Use a Mild Cleaning Solution

A gentle approach is usually best for mattress fabrics and foams. A common at-home option is:

  • Cool water + a small amount of mild liquid soap

How to apply:

  1. Lightly dampen a clean cloth with the soapy solution.
  2. Blot the stained area, working from the outside toward the center.
  3. Avoid soaking the mattress; use just enough moisture to treat the stain.
  4. Follow with a second cloth dampened with plain water to remove soapy residue.

This can help lift fresh urine stains before they set.

Step 3: Deodorize With Baking Soda

Even after cleaning, a slight smell may remain. Baking soda is often used to absorb lingering odors.

  1. Sprinkle a generous, even layer of baking soda over the cleaned area.
  2. Gently spread it with your hand so the surface is covered.
  3. Leave it on for several hours, or ideally overnight, to absorb moisture and odor.
  4. Vacuum the baking soda thoroughly once it’s dry.

This simple step can make a big difference in how the mattress smells after cleaning.

Step 4: Let the Mattress Dry Completely

Trapped moisture can lead to musty odors. To help the mattress dry:

  • Open windows or use a fan for good airflow.
  • If possible, stand the mattress on its side so air can reach more surfaces.
  • Avoid making the bed again until the area feels completely dry to the touch.

Never use high heat directly on the mattress, as this may affect certain foams or fabrics.

How Do You Remove Dried or Old Urine Stains?

Older stains can be more stubborn because they have already oxidized and set. For these:

  • Repeat the blotting and mild cleaning solution steps, even if the area is dry.
  • You may need more than one cleaning cycle to lighten older discoloration.
  • Baking soda can still help reduce long-standing odors, even if the stain doesn’t fully disappear.

Some older stains may never vanish completely, but they often can be significantly reduced in both appearance and smell.

Can You Use Strong Cleaners or Bleach on a Mattress?

Many people wonder if powerful cleaners will speed up the process. However:

  • Bleach and harsh chemicals can discolor fabrics, break down foams, or leave strong residual odors.
  • Sprays with heavy fragrances may only mask the smell instead of addressing the source.

For most mattresses, gentle, water-based cleaning methods are safer and more in line with how mattresses are typically cared for.

How Can You Prevent Future Urine Stains?

After learning how to get urine stain off mattress once, many people look for ways to protect their bed going forward. Some commonly used strategies include:

  • Using a washable, waterproof mattress protector
  • Washing sheets regularly to catch minor leaks early
  • Blotting accidents as soon as they happen

Preventive steps can make future cleanups much faster and help preserve the mattress over time.
