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

If you’re searching for how to get period blood out of a mattress, you’re not alone. Accidents happen, and blood stains can look intimidating—but with the right approach, they’re usually manageable. This guide walks you through what to do, what to avoid, and how to protect your mattress for the future.

Why Are Period Blood Stains Hard To Remove?

Period blood contains proteins that can “set” into fabric and foam, especially if hot water is used or the stain is left to dry. Mattresses are also bulky and not machine-washable, so you’re limited to surface cleaning.

Understanding this helps explain why gentle, cool, and patient cleaning methods work best when you’re figuring out how to get period blood out of a mattress.

What Should I Do First When I Notice Blood on My Mattress?

Act as soon as you can, especially if the stain is still fresh.

  1. Blot, don’t rub
    Use a clean, dry cloth or paper towel to gently blot up as much blood as possible.
    Rubbing can push the stain deeper into the mattress.

  2. Use cold water only
    Lightly dampen a cloth with cold water and blot the stain again.
    Hot water can cause the blood to set and become more difficult to remove.

  3. Avoid soaking the mattress
    Mattresses trap moisture, so use minimal water to reduce the chance of lingering dampness or odor.

How To Get Period Blood Out Of a Mattress: Step-by-Step Methods

Below are simple, commonly used household approaches. You can try one method or combine them gently over time.

Method 1: Mild Soap and Cold Water

This is a good first option for fresh stains.

  1. Mix a small amount of gentle liquid soap with cold water.
  2. Dip a clean cloth into the solution and wring it out well.
  3. Blot the stain gently—do not scrub.
  4. Use a second cloth dampened with plain cold water to remove soap residue.
  5. Blot dry with a towel and let the area air dry completely.

Method 2: Salt or Baking Soda Paste

These common pantry items can help lift stains and absorb moisture.

  1. Mix cold water with either plain salt or baking soda to form a thick paste.
  2. Spread a thin layer over the stained area.
  3. Let it sit for at least 30–60 minutes.
  4. Gently wipe away with a damp cloth.
  5. Blot with a dry towel and allow to air dry.

Can I Use Hydrogen Peroxide on Blood Stains?

Some people use 3% hydrogen peroxide on light-colored mattresses, as it can help break down blood stains. However, it may lighten or discolor fabrics and ticking, especially on darker materials.

If you choose to try it:

  1. Test a tiny amount on a hidden area first.
  2. Apply a small amount directly to the stain.
  3. Let it bubble for a short time, then blot with a clean cloth.
  4. Repeat gently if needed, and avoid over-wetting the mattress.
  5. Allow the area to dry thoroughly.

Because hydrogen peroxide can be reactive, it’s best used sparingly and carefully.

What If the Blood Stain Is Already Dry?

Dried stains often need a bit more time and patience.

  • Rehydrate with cold water: Lightly dampen the area with a cloth and cold water to soften the dried blood before trying any cleaning method.
  • Then use soap and water or a baking soda paste as described above.
  • You may need to repeat the process several times rather than using harsh scrubbing.

How Do I Dry the Mattress After Cleaning?

Keeping your mattress dry is important for comfort and longevity.

  • Blot with a dry, absorbent towel to remove as much moisture as possible.
  • Let the mattress air dry fully before putting sheets back on—near an open window or in a well-ventilated room, if possible.
  • If you use a fan, aim it at the cleaned area to speed up drying.

Avoid using direct high heat, which may affect some mattress materials.

What Common Mistakes Should I Avoid?

When learning how to get period blood out of a mattress, try to avoid:

  • Using hot water – can set protein-based stains like blood.
  • Scrubbing aggressively – can push the stain deeper and damage the fabric.
  • Over-soaking the mattress – can leave trapped moisture.
  • Skipping a spot test with stronger agents like hydrogen peroxide on colored fabrics.

How Can I Prevent Future Stains?

While no setup is perfect, a few simple steps can make accidents less stressful:

  • Use a water-resistant mattress protector to act as a barrier between your sheets and mattress.
  • Consider layering: protector + fitted sheet + optional extra sheet or towel during your period.
  • Address any new stain as soon as you notice it for the best chance of removal.
