Washable Non-Staining Fake Blood: Make Your Own in 3 Steps

bloody fingerIncreasingly, Halloween fans want to learn how to make their own washable, non-staining fake blood, ideally without food colouring, because stage blood is a key addition to so many costumes and effects. Sadly, the stage blood available in stores tends to stain, and ketchup-water recipes don’t turn out well. Seriously, though: fake blood that won’t stain – is it possible? Of course it is! Give me five minutes of your time and I’ll walk you through a simple method for making your own realistic, non-staining fake blood.

Believe me, I understand the hassle of fake blood that leaves stains. I’ve had to wash stains from my skin, clothes, and towels, as well as from my walls after some Halloween parties. So without further ado, let’s get right to my favourite method for making your own washable, non-stain version!

What You’ll Need…

Let’s begin by organizing everything that you’re going to need. Fortunately, there are actually only three ingredients you’ll need to have on hand to make your own non-staining fake blood. That’s right – three steps, three ingredients. Here’s what you’ll need:


As you may have gathered from the list of ingredients, the key difference between this and other types of homemade fake blood is the substitution of food colouring (which stains) with poster paint, which is a common type of children’s washable paint (and hence doesn’t stain).

Here’s how to make your own non-stain fake blood in three easy steps:

  1. Pour some corn syrup into a bowl. The amount you use will depend on how much blood you want to make, but as a starting point, just pour the same amount of corn syrup as you want for your finished amount of blood (i.e., if you want 4 ounces of blood, use 4 ounces of corn syrup).
  2. Add a bit of red poster paint, using no more than a teaspoon to start. It’s always easier to add more later if you need to. Mix well.
  3. You’ll notice that the blood will be rather bright. To darken it and get a more realistic look, mix in a small amount of cocoa powder. As with the paint, don’t use more than a teaspoon to start. Too much cocoa can give the blood a granular texture.

And voila – you’re done! Super easy!

Making your own stage blood is as much an art as a science, of course, so you’ll want to practice until you find the exact combination that works best for the colour you’re trying to achieve.

Hope this helps!

  1. Hi I love the steps but am I able to do this another way that only lasts up to 6 hours because I wanna scare my friends at school and what if you don’t have these ingredients to make the fake blood?

    • Hi Heidi. The only way I currently know to reduce the duration is to add water, but that will also clarify the blood and make it look brighter. If that’s not a problem for you, feel free! If you don’t have the ingredients, your best bet is to purchase the highest-quality fake blood you can find, but read the label carefully to find out about possible staining.

    • Thanks for the question Sonya. You should be able to, but to be perfectly honest I’ve never tried it so I can’t say for sure. If you try it, please definitely do let us know the results!

    • Hi veron. It can last quite a while, but may need some stirring prior to use as the cocoa can sometimes settle if it’s been sitting for a while. Let me know if you have any other questions!

  2. This worked great I made quite a bit but it worked great there was a slight stain after cleaning it off with a paper towel but it went away with a little face wash it was great even had enough to cause a big scare to my friend’s mom

  3. I need to use this for a musical, but I need to wash it off of the hands quickly. How much scrubbing does it take to get it off the hands? Would hand sanitizer do the trick? Thanks for the help!

    • Thanks for your question Yusra. I wouldn’t recommend putting anything in your eye, including this, as eyes are incredibly sensitive and doing so could easily irritate them. If you want to pretend that you’re crying blood, my advice would be to put a drop just below your eye, near the tear duct, and let it drip. Very similar effect – no risk! If you need anything else, just let me know.

  4. Do you mean corn syrup instead of the cornstarch? Cornstarch is a powder and having that powder and the cocoa powder would just make the poster paint all clumpy and not a liquid. Also, you say to start with 4 ounces of cornstarch, which also leads me to believe that you are referring to corn syrup since that is a liquid.

  5. Are the ingredients meant to include corn starch or corn syrup? I tried corn starch with the teaspoon of poster paint and it’s very dough like- not blood like. Is there a possibility of a typo in these ingredients?

  6. Help! I need a lot of blood, so I started with a cup of cornstarch. I’ve added 1.5 oz of red poster paint. I now have pink powdery corn starch. Should I be adding water?

    Thank you

    • Sorry Susan. I meant to write corn syrup, not corn starch. I’ve corrected the typo in the post. You can also water if you want to create an even more liquid effect.

  7. Planning on using this for a Jeff the Killer cosplay this weekend–glad to find an easy recipe tht won’t stain the hoodie ^^’

  8. I’m a little confused about how there is enough liquid in this recipe to make realistic fake blood since corn starch and cocoa powder are both dry and you’re using the poster paint sparingly. Am I missing something? Thanks!

  9. Hi so I have a light blue dress that i want to wear for Halloween as a creepy-Cinderella look but i dont want to buy fake blood. Will this recipe stain my clothes at all? Thanks!

    • It’s never stained anything in my personal experience. This is the safest option I have ever come across. If you’re concerned, you can of course always test-spot it on an inconspicuous section of the fabric. Let me know how it goes!

        • Corn syrup (not corn starch) is the chief ingredient. I have corrected the typo in this post. My apologies. To answer your question, you can use another kind of paint, like water-based paint if you like, but it may stain a bit.

  10. I am gonna try this year. We just bought a new house and I want to have a party for my children so I had an idea but didnt want to stain my hubby’s garage doors. So this will not stain any kind of material right? Thank you so much for your knowledge.

    • Hi Monica. I’ve used this several times and to date, it hasn’t stained anything – I’ve had no issues at all. Your husband’s garage doors should be perfectly safe.

      On a related note, cocoa, like chocolate, can stain white clothes a bit, but it’s typically very easy to wash out in the laundry and so it’s not permanent. Oxi-Clean is really good at getting tough stains out. If you’re ever worried about this in particular, simply be sure not to use too much cocoa.

      Hope this helps! Let me know if you have any other questions.
