If you’re searching “How Do i Clean Urine From a Mattress”, you’re likely dealing with a fresh accident, an older stain, or lingering smells. This guide walks you through exactly what to do, which products to avoid, and how to protect your mattress in the future.

What’s the best way to clean fresh urine from a mattress?

For fresh stains, acting quickly makes a big difference. Here’s a simple method using common household items:

  1. Blot, don’t rub

    • Use clean, dry towels or paper towels to press firmly on the wet area.
    • Avoid scrubbing, which can push urine deeper into the mattress.

  2. Apply a mild cleaning solution
    A common option is a mix of water and a small amount of gentle detergent (like dish soap). Lightly spray or dab it onto the stained area.

    • Do not oversaturate; too much liquid can soak into the mattress core.

  3. Blot again

    • Use fresh towels to lift out as much moisture and cleaner as possible.
    • Keep blotting until the area feels only slightly damp.

  4. Use baking soda for odor and moisture

    • Sprinkle a thick, even layer of baking soda over the treated area.
    • Let it sit for several hours (overnight is helpful) so it can absorb moisture and smell.

  5. Vacuum thoroughly

    • Once dry, vacuum the baking soda with an upholstery attachment if you have one.
    • Check if odor or staining remains and repeat if needed.

How do I clean dried or old urine stains from a mattress?

Old stains are usually tougher because the urine has had time to soak in and dry. You can still improve them with patience:

  1. Lightly re-dampen the stain

    • Mist the area with plain water (avoid soaking).
    • This helps loosen dried residue so cleaners can work more effectively.

  2. Apply a gentle cleaning solution

    • A mixture of water and mild detergent, or water with a small amount of white vinegar, is commonly used.
    • Lightly apply it to the stained area.

  3. Let it sit

    • Allow the solution to rest on the stain for 10–15 minutes.
    • This gives it time to break down discoloration and odor-causing residue.

  4. Blot thoroughly

    • Press with clean, dry towels until most of the moisture is removed.

  5. Deodorize with baking soda

    • Cover the area generously with baking soda and leave it for several hours or longer.
    • Vacuum it up and check the result. Multiple treatments are sometimes needed for older stains.

How do I get rid of urine smell that won’t go away?

Even after the stain fades, odor can remain inside the mattress layers. To reduce lingering smell:

  • Repeat baking soda treatments

    • Applying and vacuuming baking soda more than once can slowly reduce deep odors.

  • Improve air circulation

    • Let the mattress air out in a well‑ventilated room.
    • If possible, place it where it can receive indirect sunlight, which can help with freshening.

  • Keep moisture low

After cleaning, it’s important that the mattress is fully dry before you sleep on it:

  • A damp mattress can feel uncomfortable and may develop musty smells.
  • Drying can take several hours or longer depending on room temperature and airflow.

You can speed drying by:

  • Pointing a fan at the cleaned area
  • Opening windows for ventilation
  • Removing all bedding until the mattress feels dry to the touch

Preventive steps can save time and stress:

  • Use a waterproof mattress protector

  • Add a washable mattress pad

    • A pad on top of the protector can provide extra comfort and another layer to wash if needed.
