How Do You Get Sweat Stains Out Of a Mattress? Simple Steps That Work

If you’re wondering “How Do You Get Sweat Stains Out Of a Mattress”, you’re not alone. Yellow patches, musty smells, and discoloration from sweat are some of the most common mattress issues. The good news: with the right method, you can often lift sweat stains and freshen your mattress without harsh products or special tools.

Below, you’ll find a clear, step‑by‑step guide and answers to the most frequent questions about sweat stains on mattresses.

What Causes Sweat Stains on a Mattress?

Sweat stains form when moisture, body oils, and salts soak into the mattress fabric over time. This can lead to:

  • Yellow or brownish patches
  • Lingering odors
  • A mattress that looks older than it really is

Even with good bedding, sweat can slowly pass through sheets and a thin protector. That’s why many people eventually search for how to get sweat stains out of a mattress.

How Do You Get Sweat Stains Out Of a Mattress? (Step‑by‑Step)

1. Start With a Dry Surface

  1. Strip the bed – remove sheets, mattress protector, and any bedding.
  2. Vacuum the mattress surface to remove dust, hair, and debris. This stops dirt from mixing with your cleaning solution.

2. Make a Simple Cleaning Solution

A common home method uses mild dish soap or gentle laundry detergent plus water:

  • Mix a small amount of liquid detergent with cool or lukewarm water.
  • Avoid soaking the mattress; you only need enough solution to lightly dampen the stain.

For tougher yellowing, some people also use baking soda or a small amount of white vinegar in separate steps, which can help with odor and discoloration.

3. Spot Clean the Sweat Stain

  1. Lightly apply the solution to the stained area using a clean cloth or spray bottle.
  2. Blot, don’t scrub. Press the cloth into the stain to lift it out of the fabric. Scrubbing can push the stain deeper and rough up the fabric.
  3. Repeat as needed until you see the stain begin to fade.

🧼 Tip: Work from the outside of the stain toward the center to avoid spreading it.

4. Deodorize With Baking Soda (Optional but Helpful)

After blotting:

  1. Sprinkle a thin, even layer of dry baking soda over the cleaned area.
  2. Leave it for several hours (or overnight if possible).
  3. Vacuum the baking soda thoroughly.

Baking soda helps absorb residual moisture and neutralize odor, which is especially useful for old sweat smells.

5. Let the Mattress Dry Completely

This step is essential:

  • Allow the mattress to air dry fully before putting bedding back on.
  • If possible, open windows or use a fan to improve airflow.
  • Avoid sleeping on a damp mattress, as trapped moisture can lead to odors.

What If the Sweat Stains Are Old or Very Yellow?

Older sweat stains can be more stubborn, but you can still often improve them:

  • Repeat the cleaning cycle (detergent solution → blot → baking soda → dry).
  • Be patient; multiple light treatments are usually safer than one heavy, wet cleaning.
  • Avoid soaking the mattress; too much liquid can be hard to dry and may cause musty smells.

If the stain is deeply set into the inner layers, it may not vanish completely, but many people find that it becomes significantly lighter and less noticeable.

Can You Use Bleach or Strong Chemicals on a Mattress?

Most mattresses are not designed to handle bleach or harsh cleaners. These can:

  • Damage the fabric cover
  • Weaken some foam materials
  • Leave strong odors behind

Instead, focus on gentler methods like mild detergents, baking soda, or small amounts of white vinegar used carefully. Always test a small hidden area first, no matter what you use.

How Do You Prevent Sweat Stains From Coming Back?

Once you’ve figured out how to get sweat stains out of a mattress, prevention helps protect your effort:

  • Use a washable mattress protector for a barrier against sweat and spills.
  • Wash sheets and protectors regularly to keep sweat from building up.
  • Allow your mattress to air out occasionally by stripping the bed for a few hours.

These simple habits can reduce yellowing and help your mattress stay fresher over time.

Do I Need Professional Cleaning?

Some people choose professional cleaning if:
