How To Clean Cat Urine Out Of a Mattress: Simple Steps That Actually Help

If you’re searching for How To Clean Cat Urine Out Of a Mattress, you’re likely dealing with a fresh accident or a lingering smell you can’t seem to remove. This guide walks through practical, at-home methods to clean cat pee from a mattress, reduce odor, and protect your bed for the future.

Why Is Cat Urine So Hard To Remove From a Mattress?

Cat urine can be challenging because:

  • It soaks deep into foam and fabric.
  • As it dries, it can leave strong, persistent odors.
  • If not cleaned properly, it may encourage repeat accidents in the same spot.

Mattresses can’t go in the washing machine, so knowing How To Clean Cat Urine Out Of a Mattress safely is important for both the lifespan of your mattress and your sleeping comfort.

What Should I Do First When My Cat Pees on the Mattress?

1. Act Quickly

The sooner you treat the spot, the easier it is to remove. Fresh urine is generally simpler to clean than dried stains.

2. Blot, Don’t Rub

  • Use clean, absorbent towels or paper towels.
  • Press firmly to blot up as much liquid as possible.
  • Avoid scrubbing, which can push urine deeper into the mattress layers.

3. Protect the Rest of the Bed

If possible, remove bedding immediately and launder it according to the care instructions. Focus on the mattress once sheets and protectors are out of the way.

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

Here’s a simple, common at-home method many people use with basic household items.

Step 1: Prepare a Cleaning Solution

A commonly used option is a mixture of mild dish soap and cool water or a diluted white vinegar solution (for example, equal parts white vinegar and water). Always test a small, hidden area of your mattress fabric first to check for discoloration.

Step 2: Lightly Treat the Stain

  • Lightly spray or dab the affected area with your chosen solution.
  • Avoid soaking the mattress, which can make drying difficult.
  • Let it sit for 5–10 minutes so it can help break down the urine.

Step 3: Blot Again Thoroughly

  • Use clean, dry towels to blot up the solution.
  • Continue until the area feels only slightly damp.
  • Replace towels as they become saturated.

Step 4: Deodorize With Baking Soda

Once you’ve removed as much moisture as possible:

  • Sprinkle a generous layer of baking soda over the damp area.
  • Gently spread it so it covers the full stain.
  • Leave it for several hours or overnight, if possible, to help absorb odor and moisture.

Step 5: Vacuum Carefully

When the baking soda is fully dry:

  • Use a vacuum with a clean upholstery attachment.
  • Vacuum up all the powder slowly and thoroughly.
  • If a faint smell remains, some people choose to repeat the process once more.

What About Old or Dried Cat Urine Stains?

Dried cat urine can leave stubborn yellow stains and lingering odor. The basic approach is similar but may take more than one round:

  1. Lightly re-dampen the area with water or diluted vinegar solution.
  2. Allow it to sit a bit longer than with a fresh stain.
  3. Blot thoroughly and repeat baking soda and vacuuming.

If staining is still visible, some people choose to apply a second, lighter treatment rather than heavily soaking the mattress at once.

Can I Use Strong Chemicals or Steam Cleaners?

  • Harsh chemicals may damage mattress materials or leave strong artificial smells.
  • Steam cleaners can force moisture deeper into the mattress and make drying difficult, which may lead to other issues.

More gentle, surface-level methods are commonly preferred for mattresses. Always check your mattress care guidelines before applying any cleaning approach.

How Do I Dry the Mattress After Cleaning?

Proper drying is an important part of How To Clean Cat Urine Out Of a Mattress successfully:

  • Allow the mattress to air dry completely before putting bedding back on.
  • Open windows or use a fan to increase airflow.
  • Avoid covering the damp area with sheets or pads, which can trap moisture.

Drying time can vary depending on how much liquid was used and your room conditions.

How Can I Prevent Future Cat Urine Accidents on the Bed?

While behavior-related issues are outside the scope of mattress care, you can still help protect your mattress:

  • Use a waterproof mattress protector to create a barrier between accidents and the mattress core.
  • Clean any new accidents quickly, following the steps above.
  • Keep bedding washable and easily removable, so you can address issues promptly.
