How To Clean Cat Urine Out Of Mattress: Step‑By‑Step FAQ Guide

If you’ve woken up (or come home) to a cat accident on your bed and you’re searching “How To Clean Cat Urine Out Of Mattress”, you’re in the right place. This guide explains exactly what to do, what to avoid, and how to reduce lingering odor so your mattress stays usable and comfortable.

Why is cat urine so hard to remove from a mattress?

Cat urine is challenging because it:

  • Soaks deep into foam and padding
  • Contains uric acid crystals that can leave a strong, lingering smell
  • Can re-activate when the area gets damp again

On a mattress, you can’t simply toss it in the wash. The key is blotting, neutralizing the odor, and fully drying without over-saturating the mattress.

What should I do immediately after my cat pees on the mattress?

Acting quickly makes a big difference.

  1. Remove bedding
    Strip all sheets, covers, and protectors. Wash them separately in cool or warm water with regular detergent. Avoid very hot water at first, which can sometimes set odors in fabrics.

  2. Blot, don’t rub
    Use clean, dry towels or paper towels.

    • Press firmly to absorb as much liquid as possible.
    • Work from the outer edge of the stain inward to keep it from spreading.
    • Keep blotting until the area feels damp instead of wet.
  3. Avoid harsh chemicals at this stage
    Strong cleaners or steam can push urine deeper into the mattress or lock in odors.

How To Clean Cat Urine Out Of Mattress: Step-by-Step

1. Apply a simple cleaning solution

A common home method is a mild, water-based cleaner such as:

  • A small amount of gentle liquid soap diluted in water, or
  • A mixture of plain water and a small amount of white vinegar

Lightly spray or dab the solution onto the stained area. Do not soak the mattress. The surface should be damp, not drenched.

Blot again with a clean cloth to lift more urine and cleaner from the mattress.

2. Neutralize the odor

After surface cleaning, odor can still linger. A widely used option is baking soda:

  1. Sprinkle a generous layer of dry baking soda over the damp area.
  2. Gently pat it down so it contacts the mattress surface.
  3. Leave it for several hours or overnight so it can absorb moisture and odor.

Once it’s dry and clumpy, vacuum thoroughly using an upholstery attachment if you have one.

Can I use enzymatic cleaners on cat urine in a mattress?

Many people use enzyme-based cleaners designed for pet messes. These are commonly used because they:

  • Help break down the organic compounds in urine
  • Target lingering odors that basic cleaners may miss

If you choose to use one:

  • Follow the label directions carefully
  • Test a small, hidden area first to check for discoloration
  • Avoid over-wetting the mattress; use only as much as required

Enzyme cleaners can be especially helpful for older or recurring stains.

How do I dry the mattress properly after cleaning?

Drying matters as much as cleaning. A mattress that stays damp can develop unpleasant smells or damage over time.

Tips for drying:

  • Increase airflow:
    • Open windows if possible
    • Use a fan directed across (not straight down into) the mattress
  • Use natural sunlight when practical
    Some people place the mattress near a bright window or in a well-ventilated area during the day.
  • Allow enough time
    Make sure the mattress is completely dry on the surface and inside before replacing bedding. This can take several hours or longer, depending on materials and room conditions.

What if the cat urine stain is old or already dry?

Older stains can be more stubborn but are often still manageable.

  1. Lightly re-dampen the stained area with water (not soaking).
  2. Apply a mild cleaner or an enzyme-based cleaner according to its instructions.
  3. Let it sit for the recommended time to work on the dried urine.
  4. Blot thoroughly and use baking soda if needed to absorb odor.
  5. Vacuum when fully dry.

You may need to repeat the process a couple of times for deep or long-standing odors.

Are there things I should never do when cleaning cat urine from a mattress?

Common mistakes include:

  • Using a steam cleaner on fresh urine
    Heat and steam can push urine deeper into the mattress and may make the smell harder to remove.
  • Soaking the mattress
    Too much liquid can be difficult to dry and may cause new odors.
  • Using strong bleach directly on the mattress
    This can damage materials and cause discoloration or harsh smells.

How can I prevent future cat urine accidents on my mattress?

While accidents can still happen, a few habits may help:

  • Consider a water-resistant mattress protector to act as a barrier between your cat and the mattress surface.
  • Keep the litter box clean and accessible, which many cats prefer.
  • If your cat is suddenly having frequent accidents, it may be helpful to speak with a veterinarian or behavior professional for guidance.
