How To Clean Cat Pee Off Mattress: Simple Steps That Actually Work

If you’re searching for “How To Clean Cat Pee Off Mattress”, you’re likely dealing with a fresh accident or a lingering smell you can’t get rid of. This guide walks you through exactly what to do, why each step matters, and how to prevent stains and odors from coming back.

Why Cat Urine on a Mattress Is So Stubborn

Cat urine can be more challenging than other accidents because it contains uric acids that can leave a strong, lingering odor if not cleaned properly. On a mattress, liquid can soak deep into the layers, which makes quick action and the right cleaning method especially important.

A good cleaning routine should:

  • Remove as much liquid as possible
  • Break down the odor-causing components
  • Avoid setting the stain deeper into the mattress

How To Clean Cat Pee Off Mattress: Step-by-Step

1. Act Fast and Blot (Don’t Rub)

If the spot is still wet:

  • Strip all bedding immediately
  • Use clean, dry towels or paper towels to blot up as much urine as possible
  • Press down firmly, but do not rub, which can push urine deeper into the mattress

The goal is to lift liquid out, not spread it around.

2. Use a Gentle Cleaning Solution

A common approach is a mild cleaning solution made from items many people already have at home. One typical option is:

  • A mixture of water and a small amount of mild dish soap, or
  • A vinegar and water solution (often used in a 1:1 ratio)

Lightly spray or dab this solution onto the stained area—do not soak the mattress. Too much liquid can cause its own issues and take a long time to dry.

Blot again with a clean cloth to help remove both the urine and cleaner.

3. Tackle Odor With Baking Soda

Cat pee odor can linger even after surface cleaning. Baking soda is often used because it can help absorb smells.

  • Sprinkle a generous layer of baking soda over the cleaned area
  • Gently press it in so it contacts the surface of the mattress
  • Leave it for several hours, or overnight if possible
  • Vacuum thoroughly to remove all baking soda

If odor remains, this step can often be repeated.

How Do I Clean Dried Cat Pee From a Mattress?

Dried urine may have already left visible staining and deeper odor.

  1. Lightly re-dampen the area with water (just enough to help loosen dried residue)
  2. Blot to remove moisture
  3. Apply your cleaning solution as above
  4. Blot again, then use baking soda to help with smells

You may need to repeat the process more than once for older stains.

What Should I Avoid When Cleaning Cat Pee Off a Mattress?

Some common mistakes can make the problem worse:

  • Avoid harsh scrubbing that can damage fabric and push urine deeper
  • Avoid soaking the mattress with too much liquid cleaner
  • Avoid strong, masking fragrances alone that cover odor temporarily without truly removing it
  • Be cautious with very strong chemicals that may be too harsh for mattress fabrics or finishes

The safest approach is usually gentle, gradual cleaning rather than aggressive treatments.

How Long Will It Take My Mattress to Dry?

Drying time depends on how much liquid was used and airflow in the room. To speed things up:

  • Open windows or use a fan to improve air movement
  • If safe for your mattress type, use a low, indirect setting on a hair dryer, keeping it moving and not too close
  • Make sure the mattress is completely dry before putting bedding back on, to avoid trapped moisture and musty smells

Can the Smell Come Back After Cleaning?

Sometimes cat urine odor seems gone, then returns later. This can happen if:

  • The urine soaked deeply into the mattress layers
  • Cleaning only treated the surface
  • The mattress didn’t dry fully

If the smell returns, repeat the cleaning and baking soda process. In more persistent cases, spot-cleaning multiple times may be needed.

How Can I Prevent Future Cat Pee Accidents on My Mattress?

While this guide focuses on How To Clean Cat Pee Off Mattress, it also helps to reduce the chance of repeat accidents:

  • Use a water-resistant mattress protector to create a barrier
  • Keep litter boxes clean and accessible, especially for older cats
  • Consider limiting bedroom access if accidents are frequent, at least temporarily

These steps help protect your mattress so cleanup is easier if it happens again.
