How To Remove Blood Stains From Mattress Protector: Simple, Safe Methods That Work

If you’re searching for how to remove blood stains from mattress protector, you’re likely dealing with a fresh accident or discovering a dried stain. The good news: in many cases, you can lift blood from a mattress protector without damaging the fabric or your mattress underneath.

This guide answers common questions about blood stain removal, what to use, what to avoid, and how to protect your sleep surface long term.

Why Do Blood Stains Stick to Mattress Protectors?

Blood contains proteins that bond to fabric fibers as they dry. Heat (like hot water or a dryer) can “set” those proteins, making stains harder to remove. Mattress protectors can be:

• Fully waterproof (with a plastic or polyurethane backing)
• Water-resistant fabric
• Quilted or padded with multiple layers

Knowing what kind you have helps you choose the safest cleaning method and avoid damage to coatings or seams.

How To Remove Blood Stains From Mattress Protector: Step-by-Step

1. Should I Treat Blood Stains While They’re Fresh?

Yes. Fresh blood is much easier to remove than dried blood.

1. Remove the protector from the bed as soon as you notice the stain.
2. Blot, don’t rub. Use a clean, light-colored cloth or paper towel to gently blot up as much blood as possible.
3. Rinse with cold water. Hold the stained area under cold running water from the back of the fabric, pushing blood out of the fibers.

Avoid hot or warm water at this stage. Heat can set the stain.

2. What Cleaning Solutions Work Best on Blood Stains?

Several gentle, household solutions can help when you’re learning how to remove blood stains from mattress protector.

Common options include:

• Mild liquid detergent + cold water
• Baking soda paste (baking soda + a little cold water)
• Salt paste (table salt + cold water)
• Diluted hydrogen peroxide (check fabric care label first; best for light-colored protectors)

How to use them:

• Detergent solution:

  • Mix a small amount of mild detergent with cold water.
  • Apply to the stain with a cloth or sponge.
  • Gently dab and work it in; avoid aggressive scrubbing.
  • Rinse thoroughly with cold water.

• Baking soda or salt paste:

  • Mix enough cold water to form a spreadable paste.
  • Apply a thin layer over the stain.
  • Let sit for 15–30 minutes.
  • Gently scrape off the paste and rinse with cold water.

• Hydrogen peroxide (for white or colorfast fabrics):

  • Test a small, hidden area first.
  • Apply a small amount directly to the stain.
  • It may foam; gently blot with a clean cloth.
  • Rinse thoroughly with cold water afterward.

Can I Machine Wash a Mattress Protector With Blood Stains?

Many protectors are machine washable, but always check the care label first.

If machine washing is allowed:

1. Pre-treat the stain using one of the methods above.
2. Place the protector in the washer by itself or with similar items.
3. Use a cold water cycle and a mild detergent.
4. Avoid bleach unless the label clearly says it is safe, as it may damage waterproof layers or discolor fabric.

Drying matters too:

• Use low heat or air dry if recommended.
• High heat can damage waterproof backing or set any faint remaining stain.
• Make sure the protector is completely dry before putting it back on the bed to prevent dampness from affecting your mattress.

What If the Blood Stain Has Already Dried?

Dried stains are more stubborn but often still treatable.

1. Rehydrate the stain:
   • Soak the stained area in cold water for 30–60 minutes.
2. Apply a gentle cleaner:
   • Use detergent, baking soda paste, or carefully tested hydrogen peroxide.
3. Gently agitate:
   • Lightly rub the fabric against itself or dab with a cloth.
4. Rinse and repeat as needed before machine washing (if permitted).

Patience is important. Multiple light treatments are usually safer than one harsh one.

Are There Things I Should Avoid?

Yes, to keep your mattress protector functional and intact, avoid:

• Hot water on fresh stains (it sets proteins into fibers).
• High dryer heat if your protector has a waterproof backing.
• Strong bleach or harsh chemicals unless the label specifically allows them.
• Aggressive scrubbing, which can damage the fabric or coatings.

Will Blood Go Through the Protector Into My Mattress?

A fully waterproof protector is designed to stop liquids from reaching the mattress surface. However:

• If the protector is not fully waterproof, or
• If the spill was large or left for a long time,

blood may soak through seams or thin areas. After removing the protector, check your mattress for any marks and treat them separately if needed.

How Can I Prevent Permanent Staining in the Future?

A few simple habits can reduce lasting stains:

• Act quickly whenever you notice spills or accidents.
• Keep a spare mattress protector on hand so you can remove and wash the stained one right away.
• Follow the washing instructions closely to maintain the waterproof barrier over time.
• Inspect your protector occasionally for wear, peeling, or thinning that might reduce its effectiveness.

• Pre-treat before washing: Use mild detergent, baking soda, salt paste, or carefully tested hydrogen peroxide.
• Check the care label: Confirm whether machine washing, bleach, or heat drying are safe for your specific protector.
• Handle dried stains with patience: Soak in cold water, then treat and rinse several times if needed.
• Protect the waterproof layer: Avoid harsh chemicals and high heat that can damage coatings.
• Inspect your mattress after removing the protector to ensure no liquid has seeped through.
