Waking up to blood on your sheets can be annoying. But when you figure out the blood has soaked through to the mattress, it can be pretty stressful! Fortunately, there are easy steps you can take to clean blood off your mattress, whether you’re dealing with period stains, a nosebleed, or something else. We’ll give you easy cleaning solutions you can mix at home, and walk you through steps to remove both fresh and dried blood.

Things You Should Know

Lift as much excess blood off the stain as you can by use a damp cloth to blot the stained area.
You can use an oxygenated bleach solution, an enzyme cleaner, or a DIY solution of detergent and water to clean up blood on a mattress.
Saturate the stained area with a cleaner, and let it sit for 30 minutes before blotting up the solution.

Pre-Treating Stains

1
Strip the bed. To remove any stain from the mattress, you'll have to be able to access the mattress directly. Remove pillows, comforters, duvets, sheets, and anything else from the bed that’s covering the mattress.^{[1]

- Pre-treat sheets, pillowcases, comforters, and other washable bedding with an enzyme cleaner or stain remover if there's blood on them. Let the cleaner soak for about 15 minutes, and then wash the items in the washing machine.
2
Blot the area with a damp cloth. Soak a clean cloth in cold water. Wring out as much excess water as possible so the cloth is cold and damp. Press the cold cloth into the bloodstain and blot the area to saturate the stain. Do not rub, as this can rub the stain deeper into the mattress fibers.^{[2]

- Use cold water only, as hot water can set the stain and make it even harder to remove.

Continue alternating blotting with a damp and dry towel. When you’ve saturated the stain with water, use a clean dry towel and blot the area to soak up excess blood. Continue blotting until the area is dry and no more blood is coming off on the dry towel.^{[3]

Blood Stain Removal

1
Make a cleaning solution. There are a number of cleaning solutions you can try to clean blood stains from a mattress. Oxygenated bleach or a commercial enzyme cleaner is your best bet because these cleaners are specifically designed to break down proteins in organic matter like blood.^{[5]

Research source} Other DIY cleaning solutions you can try include:
- ½ cup (118 ml) of liquid detergent mixed with 2 tablespoons (30 ml) of water, and whisked until frothy and foamy.^{[6]

- One part baking soda mixed with two parts cold water.^{[7]

- ½ cup (55 g) cornstarch mixed into a paste with 1 tablespoon (19 g) of salt and ¼ cup (59 ml) of hydrogen peroxide.
- 1 tablespoon (15 ml) of ammonia mixed with 1 cup (235 ml) of cold water.
- 1 tablespoon (13 g) of meat tenderizer mixed into a paste with 2 teaspoons (10 ml) of cold water.
2
Saturate the stained area with the cleaner. For liquid cleaners, dip a clean cloth into your cleaner and wring out the excess. Blot the stain with the cleaner until it’s saturated. For pastes, use a knife or your finger to apply enough cleaning paste to the stain to cover it completely.^{[8]

- Memory foam mattresses especially shouldn’t get wet at all, so only apply as much cleaner as necessary to saturate the stain.^{[9]

- Don’t spray liquids directly onto a mattress. Mattresses are very absorbent, and if liquid doesn’t dry properly, it can break down the mattress fibers or cause mold problems.

Leave the solution to soak for 30 minutes. This will give the cleaner time to penetrate the stain and break down the proteins, making the blood easier to clean up.^{[10]

4
Scrub the area to loosen up stain particles. After 30 minutes, use a clean toothbrush to scrub the stain and work in the cleaner. You can also use a clean cloth to blot the area again. As you scrub or blot, the stain should start to break up and disappear.^{[11]

5
Blot up excess blood and cleaner. Soak a fresh cloth with cold water. Wring out the excess. Dab the area that you just cleaned with the cloth to remove any excess cleaner and leftover blood that may still be in the mattress.
- Continue blotting until all traces of the paste, cleaner, and blood are gone.^{[12]

6
Dry the area with a clean towel. With a fresh, dry towel, blot the area one last time to remove as much excess moisture from the mattress as possible. Lay the towel over the area you cleaned, and press down with both hands to apply pressure to the area and absorb the moisture.

Protecting the Mattress

1
Allow the mattress to air dry. Once the stain is gone, leave the air mattress bare so it can air dry for several hours, or ideally overnight. This will ensure there's no moisture trapped in the mattress, and protect the mattress from mold. To speed up the drying time, you can:
- Aim a standing fan at the mattress and turn it on high.^{[13]

- Open curtains to let sunlight dry the mattress.
- Open a window to increase the fresh air in the room.
- Take the mattress outside to dry in the sun and fresh air for a few hours.
- Use a wet/dry vacuum to suck up water.^{[14]

2
Vacuum the bed. When the mattress is completely dry, vacuum the entire surface to remove excess dirt and other particles. Regular cleaning will help keep your mattress like new for longer. Use the upholstery attachment, and vacuum the top, bottom, sides, and seams of the mattress.
3
Put on a mattress cover. Mattress covers are waterproof covers that protect the mattress from spills, stains, and other accidents. When you spill something on the mattress, for instance, the cover wicks away the moisture and prevents the mattress from getting wet.^{[15]

- Mattress pads are easy to clean. If you spill or have an accident, clean the cover according to the care instructions. Some pads will be machine washable, and others can be cleaned with a damp cloth.

Warnings

When cleaning blood that is not yours, wear non-porous gloves to protect yourself from blood-borne diseases.
