How To Get Sweat Stains Out Of Mattress: Simple Methods That Actually Help

If you’re searching for “How To Get Sweat Stains Out Of Mattress”, you’re usually dealing with yellowish marks, a musty smell, or both. The good news: most sweat stains can be lightened or removed at home with basic supplies and the right steps.

This FAQ-style guide explains why sweat stains happen, how to clean them safely, and what to avoid so you don’t damage your mattress.

Why does sweat stain a mattress in the first place?

Sweat contains water, salts, and body oils. Over time, especially if you sleep warm, this moisture can:

  • Soak through sheets and mattress protectors
  • React with mattress materials
  • Oxidize and turn yellow or brown

Light-colored mattresses show these marks more clearly. Without regular cleaning, sweat can also contribute to lingering odors.

What is the safest way to start cleaning sweat stains?

Before using any cleaner, check your mattress care tag. Many mattresses are “spot clean only”, meaning you should avoid soaking the surface.

A safe starting approach is:

  1. Vacuum the mattress
    • Use the upholstery attachment to remove dust, hair, and debris.
  2. Blot, don’t scrub
    • If the stain is fresh and still damp, gently blot with a clean cloth to absorb as much moisture as possible. Avoid rubbing, which can push sweat deeper into the mattress.

From there, you can move to a mild cleaning solution.

How To Get Sweat Stains Out Of Mattress with common household ingredients

Here’s a simple, mattress-friendly method many people use for dried sweat stains.

Step 1: Mix a gentle cleaning solution

Use a small bowl or spray bottle and combine:

  • Cool water (not hot, to avoid setting stains)
  • A small amount of mild liquid dish soap or gentle laundry detergent

You want light suds, not a thick, soapy mixture. Too much soap can be hard to remove and may leave residue.

Step 2: Spot-treat the sweat stain

  1. Lightly dampen a clean cloth with the solution.
  2. Gently dab the stained area, working from the outside inward.
  3. Avoid soaking the mattress; it should feel damp, not wet.

Step 3: Rinse with clean water

  1. Take a second cloth dampened with plain water.
  2. Dab the same area to lift away soap residue.
  3. Continue until the surface feels clean, not sticky.

Step 4: Dry thoroughly

Proper drying is critical:

  • Press a dry towel firmly on the spot to absorb excess moisture.
  • Let the mattress air dry completely. If possible, increase airflow with a fan and open windows.
  • Do not put sheets back on until the area is fully dry to the touch.

Can baking soda help with sweat stains and odor?

Yes, baking soda is often used to freshen a mattress and can help lightly lift some sweat discoloration.

A basic method:

  • Sprinkle a generous layer of baking soda over the stained area (or the entire mattress surface).
  • Let it sit for several hours, ideally overnight.
  • Vacuum thoroughly using the upholstery attachment.

Baking soda is especially useful for reducing smell, even if it doesn’t remove deep, older stains entirely.

What about stubborn or old yellow sweat stains?

Older sweat stains can be more difficult to remove completely, but you may be able to lighten them.

Some people use:

  • Gentle detergent solution, repeated several times with careful drying in between
  • A small amount of white vinegar diluted in water, applied very lightly, then rinsed and dried

If you try vinegar:

  • Always test a small hidden area first to ensure it doesn’t affect the fabric or color.
  • Use it sparingly and follow with plain water and thorough drying.

If multiple careful attempts don’t improve the stain, it may be more practical to focus on odor control and protection going forward rather than complete color restoration.

Are there things I should never use on a mattress?

To avoid damage, it’s generally best to avoid:

  • Harsh chemicals like strong bleach solutions, which can weaken fabrics and discolor foam
  • Excessive water, which can soak into the core and be slow to dry
  • Steam cleaning, unless the manufacturer’s care instructions specifically allow it
  • Abrasive scrubbing, which can damage the cover or push stains deeper

When in doubt, start mild and follow the mattress care label.

How can I prevent sweat stains from coming back?

You can’t stop sweating completely, but you can protect your mattress:

  • Use a washable mattress protector as a barrier between your body and the mattress.
  • Wash sheets and protectors regularly to remove sweat and body oils.
  • Allow your mattress to air out occasionally by stripping the bed for a few hours.

Regular light maintenance can make any future cleaning much easier.
