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

If you’re searching for “How To Clean Pee Stain Off Mattress”, you’re likely dealing with a fresh accident or an older yellow stain that won’t go away. This guide walks you through exactly what to do, using common household items and gentle methods that are safe for most mattresses.

What Causes Pee Stains on a Mattress?

Urine contains water, salts, and other organic compounds. When it soaks into a mattress:

  • Fresh pee is usually pale and easier to remove.
  • Dried pee leaves yellow stains and a lingering odor.
  • If not cleaned quickly, it can seep into deeper layers, making removal harder.

Understanding this helps explain why acting fast and using the right cleaners makes a big difference.

How To Clean Pee Stain Off Mattress (Fresh Stains)

Step 1: Blot, Don’t Rub

  1. Remove all bedding.
  2. Use clean, dry towels or paper towels.
  3. Blot gently to soak up as much liquid as possible.
  4. Avoid rubbing, which pushes urine deeper into the mattress.

Step 2: Apply a Gentle Cleaning Solution

A common simple approach is:

  • Mix 1 part mild liquid dish soap with 3–4 parts cool water in a spray bottle.
  • Lightly spray the stained area until it’s damp, not soaking.
  • Let it sit for about 5–10 minutes.

This helps break down the urine without saturating the mattress.

Step 3: Blot Again

Use a clean, dry towel to blot the area until you’ve removed as much moisture as possible. The more liquid you pull out now, the faster your mattress will dry and the less likely odor will remain.

How Do You Remove Old or Dried Pee Stains?

Dried stains usually need a bit more effort. Here’s a commonly used home method:

Step 1: Lightly Re-Dampen the Stain

  • Lightly spray the stained area with cool water.
  • This helps loosen dried residue so cleaning solutions can work better.

Step 2: Use a Vinegar-Based Solution

A widely used option for old stains is:

  • Mix equal parts white vinegar and water in a spray bottle.
  • Lightly spray the stained area—avoid over-soaking.
  • Let it sit for 10–15 minutes.
  • Blot thoroughly with a clean towel.

Vinegar is often used because it helps break down urine components and can reduce odors. However, always check your mattress care tag; some materials are sensitive to excess moisture.

Step 3: Add Baking Soda for Odor

Once the area is damp (not soaking):

  • Sprinkle a thin, even layer of baking soda over the stain.
  • Leave it for several hours, ideally overnight.
  • Vacuum the baking soda thoroughly.

Baking soda is commonly used to absorb excess moisture and neutralize smells.

Can You Use Hydrogen Peroxide on Pee Stains?

Some people use a mixture of hydrogen peroxide, baking soda, and a small amount of dish soap on light-colored mattresses.

However, be aware:

  • Hydrogen peroxide can lighten or discolor fabrics.
  • It may affect certain mattress covers or materials.
  • Always spot test a small, hidden area first.

If you’re unsure, stick to milder options like diluted vinegar and mild soap.

How Do You Get Rid of the Smell Completely?

Even after the stain looks gone, a faint odor can remain. For odor control:

  • Make sure the mattress dries completely. Moisture can trap smells.
  • Use baking soda generously and allow enough time for it to work.
  • Air out the room and, if possible, place the mattress where it can get airflow and indirect sunlight.

Some people repeat the vinegar-and-baking-soda process more than once for stubborn odors.

How Long Does a Mattress Take to Dry After Cleaning?

Drying time depends on how wet the mattress got and room conditions. To help it dry:

  • Use fans to increase air circulation.
  • Open windows if weather allows.
  • Avoid putting sheets back on until the mattress feels completely dry to the touch.

Allowing proper drying helps prevent lingering odors and keeps the mattress fresh.

How Can You Prevent Future Pee Stains?

While you can’t always prevent accidents, you can limit the damage:

  • Use a water-resistant mattress protector to keep liquids from soaking in.
  • Address accidents as soon as you notice them.
  • Keep a simple cleaning kit (towels, mild soap, spray bottle, baking soda) handy.
