How To Get Blood Stains Out Of a Mattress: Simple, Effective Methods That Work

If you’re searching for How To Get Blood Stains Out Of a Mattress, you’re usually dealing with a fresh accident or an old, stubborn mark. The good news: with the right approach, many blood stains can be significantly lightened or removed without damaging your mattress.

Below are clear, step‑by‑step answers to the most common questions about cleaning blood from a mattress.

Why Are Blood Stains on a Mattress So Hard to Remove?

Blood contains proteins that bond to fabric fibers as they dry, which is why dried stains are tougher to treat than fresh ones. Heat can “set” these proteins, making the stain even harder to lift.

This is why the basic rules for How To Get Blood Stains Out Of a Mattress are:

  • Act as quickly as possible
  • Use cold water only, never hot
  • Blot gently instead of scrubbing

What Should I Do First When Blood Gets on a Mattress?

Step 1: Act Fast and Blot, Don’t Rub

  1. Strip the bed immediately. Remove sheets and bedding so the stain doesn’t spread.
  2. Use a clean, dry cloth or paper towel to blot the fresh blood.
    • Press gently to absorb liquid.
    • Avoid rubbing, which can push blood deeper into the mattress.

Step 2: Use Cold Water Only

  1. Lightly dampen a cloth with cold water.
  2. Blot the stained area again, alternating between damp cloth and dry cloth to lift as much blood as possible.

If the stain is still visible after this step (it usually will be), you can move on to mild cleaners.

What Household Items Can Help Remove Blood Stains?

For many people, basic pantry and cleaning ingredients are enough. Always test a small hidden spot first to be sure they don’t discolor your mattress fabric.

1. Mild Dish Soap Solution

This is one of the gentlest options:

  1. Mix a small amount of mild liquid dish soap with cold water to create light suds.
  2. Dip a cloth into the soapy water and blot the stain, working from the outside in.
  3. Use a separate cloth dampened with plain cold water to blot away soap residue.
  4. Finish by blotting with a dry towel to remove excess moisture.

2. Baking Soda Paste

Baking soda can help lift stains and reduce lingering odors:

  1. Mix 1 part cold water with 2 parts baking soda to make a spreadable paste.
  2. Apply a thin layer directly on the stained area.
  3. Let it sit for at least 30 minutes (longer for older stains).
  4. Gently scrape off the dry paste and vacuum the residue.

3. Hydrogen Peroxide (Use With Caution)

Hydrogen peroxide can be effective on blood, but it may lighten or discolor some fabrics.

  1. Use 3% hydrogen peroxide (the common strength sold for household use).
  2. Apply a small amount to a clean cloth, not directly to the mattress.
  3. Dab the stain lightly and let it bubble for a few minutes.
  4. Blot with a dry cloth to remove moisture.
  5. Follow with cold water blotting if needed.

If you’re concerned about discoloration, test a tiny, hidden area first.

How Do I Get Dried or Old Blood Stains Out of a Mattress?

Older stains need more time and patience, but they can sometimes be reduced.

  1. Rehydrate the stain with a cloth dampened in cold water, and let it sit on the area for 10–15 minutes.
  2. Try the dish soap method first, since it’s gentle.
  3. If the stain remains, consider:
    • A baking soda paste left on for 1–2 hours
    • Careful use of hydrogen peroxide on light‑colored fabrics

You may need to repeat the process several times. Older stains may not disappear completely but can usually be made less noticeable.

How Should I Dry the Mattress After Cleaning?

Moisture left inside a mattress can cause long‑term issues, so drying thoroughly is important.

  • Blot up as much liquid as possible with dry towels.
  • Let the mattress air dry in a well‑ventilated room.
  • If possible, use a fan aimed at the damp area.
  • Avoid putting bedding back on until the mattress is completely dry to the touch.

Can I Use Hot Water, a Steam Cleaner, or Harsh Chemicals?

For How To Get Blood Stains Out Of a Mattress, some common cleaning habits can backfire:

  • Hot water: Can set protein stains like blood, making them harder to remove.
  • Steam cleaners: The combination of heat and moisture may push the stain deeper and set it in.
  • Bleach or strong chemicals: May damage mattress fabrics, cause discoloration, or leave strong odors.

Sticking to cold water and mild cleaners is usually safer for both the stain and the mattress.

How Can I Prevent Future Blood Stains on a Mattress?

While accidents can’t always be avoided, you can make cleanup much easier:

  • Use a waterproof mattress protector to create a barrier between spills and the mattress core.
  • Address any stain as soon as you notice it, before it dries.
  • Keep basic supplies (clean cloths, baking soda, mild soap) handy so you can respond quickly.
