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

If you’re searching for “How To Clean Pee Stains From Mattress”, you’re usually dealing with a fresh accident, an old yellow stain, or a lingering smell you can’t get rid of. This guide walks you through what to do step by step, using common household products and gentle methods that work with most mattress types.

What Happens When Pee Gets on a Mattress?

Urine can soak deep into the mattress layers. If it isn’t cleaned properly, it can leave:

  • Visible stains (yellow or darker patches)
  • Lingering odors
  • Crunchy or stiff spots where it dried

Because mattresses can’t be machine-washed, knowing how to clean pee stains from mattress surfaces safely and thoroughly makes a big difference in how long your mattress stays usable.

How Do I Clean Fresh Pee Stains From a Mattress?

Fresh stains are usually easier to handle than old ones.

Step 1: Blot, Don’t Rub

  • Use paper towels or a clean, absorbent cloth.
  • Gently press on the wet area to soak up as much liquid as possible.
  • Avoid rubbing, which can push urine deeper into the mattress.

Step 2: Apply a Mild Cleaning Solution

A simple option many people use:

  • Mix equal parts cool water and white vinegar in a spray bottle.
  • Lightly spray the stained area until damp (not soaked).
  • Let it sit for about 10–15 minutes.

Vinegar helps break down urine and reduces odor without harsh chemicals.

Step 3: Blot Again

  • After the solution has sat, blot again with clean, dry cloths.
  • Repeat until you’ve lifted as much moisture as you reasonably can.

Step 4: Use Baking Soda for Odor

  • Sprinkle a generous layer of dry baking soda over the area.
  • Leave it for several hours, or overnight if possible, to absorb moisture and smells.
  • Vacuum the baking soda thoroughly.

How Do I Remove Old or Dried Pee Stains?

Older stains can be tougher and more set in, but they often improve with patience.

Step 1: Lightly Re-Dampen the Area

  • Mist the stained area with plain water or a mild water–vinegar mix.
  • You want it damp enough to reactivate the stain slightly, but not soaking.

Step 2: Use a Stronger Cleaning Mix (Still Gentle)

A commonly used mix for dried stains:

  • 1 part white vinegar
  • 2 parts cool water
  • Optional: a small amount of mild liquid detergent

Spray lightly, let it sit for 15–20 minutes, then blot thoroughly.

Step 3: Repeat and Add Baking Soda

Stubborn stains may need more than one round:

  • Reapply the cleaning mix if needed.
  • Finish with a thick layer of baking soda and let it sit for several hours before vacuuming.

You may not always get the fabric looking brand-new, but odor and discoloration often improve noticeably with each treatment.

How Do I Get Rid of the Smell for Good?

Odor can linger even after the stain looks lighter. To tackle smell:

  • Air out the mattress: If possible, stand it up near an open window or in a well-ventilated room.
  • Use baking soda generously: A deep layer over the affected area can help absorb smells.
  • Give it time: Several hours or even a full day with baking soda can be more effective than rushing.

Avoid heavy perfumes or strong sprays that only cover the smell temporarily.

Can I Use Bleach or Harsh Cleaners?

Most mattress makers do not recommend bleach or very harsh chemicals because they can:

  • Damage fabric and inner materials
  • Discolor the surface
  • Leave strong, lingering chemical odors

It’s usually safer to stick with mild cleaners, cool water, and baking soda unless your mattress care label clearly allows something stronger.

How Long Does It Take a Mattress to Dry After Cleaning?

Drying time depends on how wet it got and your room conditions.

To speed drying:

  • Open windows or use a fan to keep air moving.
  • If possible, place the mattress in a vertical position so air reaches more surfaces.
  • Avoid putting sheets or covers back on until the area is fully dry to the touch.

Many people find it wise to clean earlier in the day so the mattress can dry before night.

How Can I Prevent Future Pee Stains?

Once you’ve learned how to clean pee stains from mattress surfaces, prevention usually feels much more appealing:

  • Use a water-resistant mattress protector to keep liquids from soaking in.
  • For children or pets, consider washable mattress pads or extra absorbent layers on top.
  • Clean accidents as soon as they happen to keep them from setting in.
