How Do You Remove Cat Urine From a Mattress? Simple Steps That Actually Help

If you’re searching “How Do You Remove Cat Urine From a Mattress”, you’re likely dealing with a fresh accident, a lingering smell, or a stubborn yellow stain. This guide walks you through practical, at‑home methods to clean cat urine from a mattress, reduce odour, and protect your bed from long‑term damage.

Why Cat Urine Is So Hard to Remove

Cat urine is more than just liquid on fabric. As it dries, it can leave behind:

  • Strong-smelling compounds that cling to fabrics and foam
  • Yellowish stains that can settle deep into the mattress layers
  • Crystallized residues that re-activate with moisture (including sweat or humidity)

That’s why simply spraying air freshener or using plain water usually isn’t enough. The mattress needs targeted cleaning to remove both the moisture and the odour-causing components.

How Do You Remove Cat Urine From a Mattress Step by Step?

1. Act Quickly and Blot, Don’t Rub

  1. Strip the bed: Remove sheets, protectors, and bedding for separate washing.
  2. Blot the area with clean, dry cloths or paper towels.
    • Press firmly to absorb as much liquid as possible.
    • Avoid rubbing, which can push urine deeper into the mattress.

The more urine you lift at this stage, the easier the rest of the process becomes.

2. Use a Gentle Cleaning Solution

A common at-home approach uses mild detergent and cool water:

  1. Mix a small amount of mild liquid detergent with cool water.
  2. Lightly dab the solution onto the stained area with a clean cloth.
  3. Blot again with a separate dry cloth to remove moisture.

Avoid soaking the mattress. Too much liquid can spread the stain and take a long time to dry, which may create new issues.

3. Address Odour With Household Ingredients

Many people find that baking soda helps reduce odours in fabrics:

  1. Sprinkle a generous layer of dry baking soda over the treated area.
  2. Gently pat it in so it reaches surface fibres.
  3. Leave it on for several hours or overnight so it can absorb moisture and smells.
  4. Vacuum thoroughly to remove all residue.

This step can be repeated if the smell lingers.

What If the Cat Urine Has Already Dried?

Dried urine can be trickier because it may have:

  • Penetrated deeper into the mattress
  • Left behind more noticeable stains
  • Built up a stronger odour

For dried spots:

  1. Lightly dampen the area with cool water (do not soak).
  2. Repeat the detergent solution and blotting process.
  3. Follow up with baking soda to help with odour.

In some cases, very old or severe stains may not disappear completely, but the above steps can often make them significantly less noticeable and more comfortable to sleep on.

Is Vinegar Safe to Use on a Mattress?

Many home tips suggest vinegar for odours. While some people use diluted white vinegar on fabrics, it’s important to:

  • Test on a small, hidden area first to check for discolouration
  • Use it sparingly and avoid over-saturating the mattress
  • Ensure the mattress dries thoroughly afterward

If used, vinegar is usually followed by baking soda to help neutralize the remaining smell.

How Do You Remove Cat Urine From a Mattress Without Damaging It?

Protecting your mattress while cleaning is just as important as removing the stain:

  • Avoid harsh chemicals or bleach, which may damage fabrics and foams.
  • Do not steam clean most mattresses; the heat and moisture can drive urine deeper.
  • Limit moisture: use damp, not soaking-wet, cloths.
  • Dry completely: allow the mattress to air out in a well-ventilated room. A fan can help.

If you’re unsure about your mattress materials, check any attached care label for general cleaning guidance.

Will the Smell Attract the Cat Back to the Bed?

Cats may revisit areas where they can still smell traces of urine, even if humans barely notice it. That’s why:

  • Thorough odour reduction is important.
  • Using absorbent powders like baking soda and repeating the process can help.
  • Keeping the bedroom door closed temporarily or adding a waterproof protector once the mattress is dry may reduce repeat accidents on the bed itself.

If accidents are frequent, some people also reassess litter box location, cleanliness, or substrate to encourage consistent use, but that falls outside mattress care.

How Long Will It Take the Mattress to Dry?

Drying time varies with:

  • Room temperature
  • Airflow
  • How much liquid was used during cleaning

Generally, allow many hours, often a full day, for the mattress to dry before putting bedding back on. Sleeping on a damp mattress can be uncomfortable and may interfere with the cleaning results.
