How To Clean Up Pee From Mattress: Simple Steps That Actually Work

If you’re searching for “How To Clean Up Pee From Mattress”, you probably need an answer right now—before stains and smells set in. This guide walks through exactly what to do, what to avoid, and how to handle both fresh and dried urine on a mattress.

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

When urine hits a mattress, it can soak into the foam and fabric, leading to stains and lingering odor. Acting quickly gives you the best chance of restoring your mattress.

Step-by-step: Fresh pee spills

  1. Blot, don’t rub

    • Use clean, dry towels or paper towels.
    • Press firmly to soak up as much liquid as possible.
    • Avoid rubbing, which can push urine deeper into the mattress.

  2. Apply a mild cleaning solution
    A simple mixture is:

    • 1 part white vinegar
    • 1–2 parts water
    • A small amount of gentle liquid dish soap (optional)

    Lightly spray or dab the area. Do not soak the mattress; too much liquid can be hard to dry out.

  3. Blot again

    • Use a fresh, dry cloth to remove excess moisture and solution.
    • Press down repeatedly until the area feels only slightly damp.

  4. Deodorize with baking soda

    • Sprinkle a generous layer of baking soda over the treated area.
    • Gently spread it to cover the whole spot.
    • Leave it for several hours, or overnight if possible, to absorb moisture and odor.

  5. Vacuum thoroughly

    • Once the baking soda is completely dry, vacuum it up.
    • Go over the area slowly to remove all residue.

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

How do you clean dried or old pee stains from a mattress?

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

  1. Lightly dampen the area

    • Use a spray bottle with plain water to moisten (not soak) the stained area.
    • This can help loosen dried urine.

  2. Use a vinegar solution again

    • Apply the same water and white vinegar mix.
    • Let it sit for 10–15 minutes.

  3. Blot and deodorize

    • Blot with clean towels.
    • Apply baking soda generously and let it sit for several hours.
    • Vacuum when dry.

  4. Consider repeating over several days
    For older stains, multiple light treatments usually work better than one heavy soaking.

Will the urine smell go away completely?

In many cases, yes, the smell can be greatly reduced or eliminated with patience and proper cleaning. A few things to keep in mind:

  • Odor often lingers if moisture is trapped inside the mattress. Proper drying is just as important as cleaning.
  • Very deep or old stains may never disappear completely, but they can usually be made far less noticeable.
  • Avoid strong perfumes or heavily scented sprays that only mask the smell without addressing the source.

How can I dry my mattress after cleaning?

A damp mattress can develop unpleasant odors and may take a long time to dry if you’re not careful.

Helpful drying tips:

  • Place the mattress in a well-ventilated room.
  • Open windows or use a fan to increase air flow.
  • If available, a cool or low-heat setting on a hair dryer can help spot-dry damp areas—keep it moving and do not overheat one spot.
  • Avoid placing a wet or very damp mattress directly back on a non-ventilated surface without a breathable base.

Only put bedding back on when the mattress feels dry to the touch.

What common mistakes should I avoid?

When figuring out How To Clean Up Pee From Mattress, avoiding certain habits can save your mattress:

  • Do not scrub hard: This can push urine deeper and damage delicate fabrics.
  • Don’t oversaturate with water or cleaner: Too much liquid can soak into the core and be difficult to dry.
  • Avoid harsh chemicals or bleach: These can discolor the fabric and may be too strong for mattress materials.
  • Don’t ignore the problem: The longer urine sits, the more it can set into the foam and fibers.

How can I prevent future pee stains on a mattress?

Prevention makes cleanup much easier next time:

  • Use a water-resistant or waterproof mattress protector to create a barrier between spills and the mattress.
  • Consider washable mattress pads that can be removed and laundered.
  • For children, pets, or frequent spills, extra layers (protector + pad) can help keep the mattress itself cleaner for longer.
