First off, like, *everything* says fake blood is a pain in the butt to get out of clothes. Seriously. Whether it’s the super cheap stuff you grabbed at the dollar store (been there, done that, got the stained t-shirt), the homemade corn syrup concoction you whipped up (sticky city!), or even the “fancy” FX blood that promised the world, it *usually* ends up being a stain-fest. Especially on a white shirt? Forget about it. You might as well just declare that shirt a casualty of war.
Now, some people *swear* by hairspray or finishing spray. The idea is you slap on the fake blood, give it a good blast of the spray, and let it, I dunno, “seal” or something? Apparently, it *can* make the prop (key word: prop, not clothes!) dry to the touch pretty quickly. But whether that translates to stain-proof clothing? Mmm, jury’s still out. I’m skeptical. I’ve tried hairspray for EVERYTHING.
The thing is, fake blood is often made with corn syrup, which, let’s face it, is basically sugar. Sugar *loves* to stain. So, spraying something on top might help it dry faster, but it’s probably not going to stop it from sinking into the fibers of your clothes.
Then there’s the washable fake blood. Yeah, “washable.” In theory, right? Like, I bought some “washable” paint for my kid once, and guess what? I’m still finding purple splotches on the walls three years later. My point is, “washable” is a relative term. It *might* come out…or it might just fade to a slightly less offensive shade of red.
Honestly? If you’re spraying it, you’re kinda committed. Think about the effect you want. Big splatters? Drips? Smears? Go for it, be artistic, be gory! Just know that you’re probably sacrificing that article of clothing. Maybe snag something from Goodwill specifically for this bloody purpose? That’s always a smart move.
