- Act fast: fresh blood is far easier to lift than blood that has been down for more than 24 hours.
- Blot, don't rub: press with a clean, dry white cloth or paper towels.
- Pretest any product on a hidden spot first and stop if color transfers or changes.
Blood on a floor is a protein stain that sets in the longer it sits, so fresh spills are the ones to act on first. Heat is the real danger, because warm or hot water can set it into wood, tile or vinyl before you've wiped it up. Fresh blood usually lifts with cool water, but a spot that has been drying for more than a day may only lighten, not vanish.
Blot up as much blood as you can with a dry towel before any water touches it, so it doesn't spread across the boards. A blood stain on hardwood floor needs only a barely damp cloth, since standing water can swell the wood. After you clean blood stains on vinyl flooring, rinse the surface with clean water so no dull film is left.

5 steps
Step by step
Step 1 of 5
Blot up the liquid
Lay a clean, dry white cloth or white paper towels over the blood and press gently to absorb it. Switch to a dry part of the cloth as it fills, and keep pressing until little more comes off. Don't rub, because rubbing spreads the stain and works it into the floor.
Step 2 of 5
Wipe with cool water
Dip a sponge or cloth in cool water, wring it out well, and wipe the spot from its outer edge toward the middle. On wood, dry the area right away with a clean cloth; on tile and vinyl, dry the spot with a clean cloth when you're done.
Careful. Never use hot water here, because it sets blood into the floor.
Step 3 of 5
Wash tile with detergent
If color remains on tile, wash the spot with laundry detergent in warm water, using a brush or sponge. Rinse well with clear water and let the tile dry before you judge the result. Skip this step on wood and vinyl.
Step 4 of 5
Polish wood once dry
Once the wood is completely dry, polish or wax it as you normally would. Tile and vinyl don't need this step.
Step 5 of 5
Bleach vinyl as the last step
If the stain is still visible on vinyl, mix 1 quart water and 1/2 cup chlorine bleach. Sponge or blot the spot until it's gone, then rinse with clear water and dry with a clean cloth.
Tip. Only do this after everything else is rinsed and dry.

Best products for blood on laminate & vinyl floors
Look for a cleaner made for your exact floor type, and use only a product that names that surface on its label.
Amazon Basics Microfiber Cleaning Cloths
How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on laminate & vinyl floors, and its directions fit the steps above.
Finished the steps? How does it look?
Nice work. Let it dry completely and check it again in good light. Here is what done looks like:
How to tell it's really gone →A faint mark usually needs one more round, not a stronger product.
If the stain was already dried or set, the method changes.
Old, dried or set-in stains →When to call a professional →How to tell it's working
Each blot should pick up more red onto the cloth, and the wiped patch should blend back into the floor as it dries. If the area dries brown or dull and stays that way after two rounds of cool water, the blood has set, so switch to the section on old and set-in stains.
What changes for yours
Adjust for your laminate & vinyl floors
Hardwood and wood floors
Wood only gets the cool-water wipe and a quick drying, with no detergent or bleach. Once it's dry, polish or wax it as usual, since the detergent and bleach steps are for tile and vinyl.
If a faint mark remains after one pass, repeat the cool-water wipe and dry again instead of wetting the wood more.
Tile floors
Tile is the one floor that gets the detergent wash in step three, since the cool-water wipe may not lift all of it. Wash only the stained spot, rinse with clear water, and let it dry before you judge the result.
If the stain has reached the grout lines, the Grout guide covers those lines in more detail. Keep the wash light and avoid soaking the tile.
Vinyl flooring
Vinyl gets the cool-water wipe first, and the bleach mix only if color stays behind. Bleach goes last, after the spot has been rinsed and dried, and only on vinyl.
Vinyl can't take detergents, which can leave a dull film, so the tile wash stays off it. If the stain won't lift, stick to the bleach step rather than scrubbing harder.
Old, dried or set-in stains
Old blood on wood takes patience, and the realistic goal is to lift most of the color rather than expect a perfect result on the first try. Dried and old protein stains often need several rounds of treatment before they're gone.
Start by brushing off any crusted matter with a dry, soft white cloth, so the cool water can reach the stain. Then wipe with a cloth dipped in cool water, dry the wood right away, and repeat the wipe as many times as it takes. Don't soak the wood, since a soak is something wood can't take.
Once the color stops lifting, a faint mark can remain in the grain, and more wetting isn't the answer. At that point, a flooring pro can tell whether the board needs refinishing rather than another round of wiping.
Vinegar, baking soda, peroxide and more
Do home remedies work on blood on laminate & vinyl floors?
Many home remedies promise to lift blood, but most of them don't belong on a floor with fresh or dried blood. Cool water, a dry cloth and a tile detergent wash handle blood, with the bleach mix reserved for vinyl only.

Chemical safety
Never mix these
Some products in this guide react dangerously with each other. Use them one at a time and rinse with water in between.
Chlorine bleach + Hydrogen peroxide (3%)
Washington State's health department says bleach reacts with hydrogen peroxide, and Clorox says not to mix bleach with other household chemicals.
If they mix by accident: Don't use the mixture; ventilate the room and avoid breathing fumes or touching it; call Poison Control at 1-800-222-1222 for disposal advice or if anyone feels unwell.
What makes it worse
Mistakes to avoid
Don't mix bleach with other cleaners
Chlorine bleach must never be mixed with ammonia, vinegar, other acids or rubbing alcohol, because the mix gives off toxic fumes. Rinse each product out with plain water before you move to the next one.
Don't use bleach on wood or tile
Chlorine bleach is listed for vinyl only, so keep it off wood and tile even if the spot is stubborn. Stick to the wood and tile steps and accept a faint mark rather than gambling on the finish.
Don't start with hot water
Heat is what sets blood into the surface, so the first pass should always be cool water on a cloth that's only barely damp. Warm water can turn a fresh spill into a stubborn one before you've had a chance to lift it. Stick with cool water and blot again rather than switching to heat.
Don't rub the spill across the floor
Blot the liquid up with a clean, dry white cloth or white paper towels and lift it straight off the surface. Rubbing drags the blood outward and can damage the surface under it, which leaves a bigger mark to deal with later.
Don't skip the test on a hidden spot
Any remover, including the diluted bleach for vinyl, can change the color of a floor. Try it on a hidden corner or inside a closet first, and stop if color transfers onto your cloth or the finish looks different.
When to call a professional
Call a professional if the blood has soaked into a seam, a gap between boards or the grout of a tile floor and still shows after a cool-water wipe and a gentle cleaner. On vinyl or linoleum, reach out to the maker's technical service before trying anything stronger, and say how long the blood sat and what you've already used.
Questions
Does blood stain hardwood floors?
Yes, blood can leave a mark on hardwood, especially if it sits and dries. Wipe it with a cloth dipped in cool water as soon as you can, and dry the wood right away.
Can hot water get blood out of a floor?
No. Hot water can set the stain into the floor, so use cool water from the first wipe to the last.
Will dried blood come out of wood floors?
It can, but dried blood may need several rounds, and a faint mark can remain. Brush off the crust, wipe with cool water, dry right away, and repeat.
Can I use hydrogen peroxide on blood on a floor?
Only the mild drugstore antiseptic kind, and only after testing a hidden spot. It's a bleach, so don't use the stronger hair-bleaching kind, and keep it away from metal tools.
Can blood soak into tile grout?
It can reach the grout lines around the tile. Blot first, treat the stain on the tile face with the wash, and see the Grout guide for lines that still show color.
Can I use bleach on blood on vinyl?
Yes, but only on vinyl, and only as the last step once cool water has failed. Mix 1 quart of water with 1/2 cup of chlorine bleach, sponge the spot until it's gone, then rinse with clear water and dry with a clean cloth.
Is vinegar safe to use on a blood spot?
Only on laminate, and only well diluted. Use about 1 cup of household vinegar to a gallon of warm water, and keep the cloth barely damp, because laminate shouldn't sit in water. Never mix it with bleach, since the combination gives off toxic fumes.
Can I use rubbing alcohol on a blood spot on laminate?
Not as a first step. Rubbing alcohol on a clean cloth is meant for marks like marker, crayon and tar, so start with cool water on the blood and keep the alcohol for those marks.
Can a rubber-backed mat sit on a blood spot while it dries?
No. Rubber and latex backings can permanently mark a floor, so keep any mat with that kind of backing off the spot until it's completely dry and clean.
