How To Get Urine Stains Out Of Mattress: Simple Steps That Actually Help

If you’re searching for “How To Get Urine Stains Out Of Mattress,” you’re likely dealing with a fresh accident or an older, set-in stain. This guide walks you through exactly what to do, why each step matters, and how to handle both fresh and dried urine stains as safely and effectively as possible.

What Happens When Urine Gets on a Mattress?

Urine can soak into the mattress layers quickly. That can leave:

  • Visible stains (yellowish spots)
  • Odors that linger
  • Moisture that may affect comfort and mattress longevity

Because most mattresses cannot go in a washing machine, learning how to get urine stains out of mattress surfaces with gentle, targeted cleaning is important.

First Question: Is the Urine Stain Fresh or Dry?

How to handle a fresh urine stain

If the accident just happened:

  1. Remove bedding immediately
    Take off sheets, protectors, and covers so the urine doesn’t spread further.

  2. Blot, don’t rub
    Use clean, dry towels or paper towels to gently press the area.
    Goal: Soak up as much liquid as possible without pushing it deeper.

  3. Apply a mild cleaning solution
    A commonly used approach is:

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

    Lightly spray or dab the area. Avoid soaking the mattress; too much liquid is hard to dry.

  4. Blot again thoroughly
    Press with fresh, dry towels to remove as much moisture from the mattress as you can.

  5. Dry the mattress carefully

    • Allow plenty of airflow
    • Use a fan if available
    • Keep the area in a well-ventilated room

    Avoid sleeping directly on a damp mattress to prevent discomfort and possible odors.

How to treat dried or old urine stains

Older stains are usually more stubborn and may need a bit more time:

  1. Lightly re-dampen the stain
    Use a small amount of cool water so cleaning products can work into the spot. Avoid oversaturating.

  2. Use a gentle cleaning mixture
    Many people find success with:

    • Mild detergent and water
    • Or a solution designed to help break down organic stains

    Apply sparingly, focusing on the stained area.

  3. Let it sit briefly
    Give the solution some contact time (often around 10–15 minutes is reasonable) while monitoring the moisture level.

  4. Blot, then air dry
    Remove as much moisture as possible, then let the mattress dry fully. This may take several hours.

How To Get Urine Stains Out Of Mattress Without Damaging It

What should I avoid when cleaning urine from a mattress?

To protect the materials inside your mattress, it’s generally wise to:

  • Avoid hot water, which can sometimes set stains further.
  • Avoid harsh chemicals or bleach, which may discolor fabric or damage foams.
  • Avoid scrubbing aggressively, which can spread the stain and wear down the surface.
  • Avoid oversaturating with liquid; deep moisture can be difficult to dry completely.

Can baking soda help with mattress urine stains?

Baking soda is often used to help with moisture and odor:

  • Sprinkle a light layer over the damp, cleaned area.
  • Let it sit for several hours or until completely dry.
  • Vacuum gently to remove the powder.

This step can be especially helpful after dealing with an older stain.

Common Follow-Up Questions About Urine and Mattresses

Will the urine smell ever fully go away?

Odors can fade over time with proper cleaning, thorough drying, and some patience. Repeating a gentle clean-and-dry cycle may help if a smell lingers. Good airflow in the room and baking soda can support the process.

Can I use a steam cleaner or carpet cleaner on my mattress?

Many mattresses are not designed for high heat or heavy moisture. Steam and deep cleaners can push water further inside and may not allow proper drying. Always check your mattress care guidelines before using these tools.

When is a stain too old to fix?

Very old stains may not fully disappear, but you can often reduce their appearance and odor. Even if the stain remains faintly visible, a careful cleaning can still make the mattress more comfortable to sleep on.

How to Prevent Future Urine Stains on a Mattress

Once you’ve learned how to get urine stains out of mattress surfaces, it helps to protect your bed going forward:

  • Use a water-resistant mattress protector to create a barrier between spills and mattress foam or springs.
  • Wash bedding regularly so minor accidents don’t have time to soak in.
  • Address future accidents as soon as possible for the best chance at avoiding stains and odors.
