I cut myself quite often (not a masochist, just simply like playing with knifes - and i pay the price for it). Easiest way to clean bloostains is an lemon-ammonia solution. Lemon is mostly to make it smell better. Ammonia smells rather badly.
Does that remove forensic traces though, like the police would look for after a murder? ASKING FOR A FRIEND, I SWEAR
She has two Ns... And she's not always watching, or at least not in the right direction <taps @Tenderiser on the shoulder from where I'm hiding in the shadows, dusappears in a cloud of...hmm, Junebugs?>
It's five AM and you expect me to be able to think of a silly pun to respond with?? On topic, if only terrible in context, I genuinely just googled 'wedding reception' to make sure that a reception is, in fact, a part of a wedding and not a funeral, because that's how tired I am. And demonstrative of how much I know about weddings. I have a very narrow knowledge base when it comes to weddings.
From what my old boss told me as an apprentice carpet layer, that club soda could get out wine stains in carpet. So in theory it should work to get the stain of blood out as well, but as for completely removing the DNA trace that will get picked up by luminol (should they investigate the house), I am not too sure. If it is a white carpet you could just bleach the area afterwards to remove the residual evidence left behind. On colored carpet maybe an intense deep steam cleaning to destroy the DNA left behind. Chances are they won't be pulling up the carpet to check for evidence on the pad underneath, or the sub-floor under that. Not too sure. On Tile or wood, I would just use Coke or Pepsi to get rid of the stains and DNA. Stuff is so acidic that it can eat nails if you leave them in a container to soak in it long enough.
Generally speaking, ammonia will 'clean' most things. BTW. I am talking about ammonia here, not "househould ammonia" which is diluted in water and known chemically as Ammonium Hydroxide. Ammonia will probably destroy DNA, never tried it personally. In terms of DNA, anything that is hostile to organic compounds is good - like sodium hydroxide for instance (also known as 'Lye' and 'Caustic Soda'). By the way, Sodium Hydroxide is pretty powerful stuff. It is particularly good as a DNA destroyer because Sodium Hydroxide destroyes proteins (which includes DNA). Luminol reacts with iron i think in the blood (heamoglobin/maeglobin). So ammonia or sodium hydroxide won't get rid of all the iron in the blood and trace ammounts will still remain (though most will wish away). Do to that, perhaps the best way it to apply a highly oxidizing agent to the surface to neutralise the iron by turning it into iron oxide (rust). Hydrogen peroxide works well for this if i remember my chemisty correctly. So really, If i was trying to... erm... 'remove'... a certain blood 'stain' from my carpet. I would first wash it with ammonia (in solution probably as it makes it easier (and less toxic) to clean). Then apply some sodium hydroxide to destroy the DNA and lastly some hydrogen peroxide to remove the reacting iron. Mind you, you probably wouldn't have a carpet left after applying such caustic substances. But anyway...
Think I remember that Luminol is a one-shot deal, so if you can get a bucket of that for cleanup you should be golden ... Or not.
Personally I would think that luminol is not nearly as effective as hollywood makes it out to be. Might ask my cop buddy if he knows anything about it.
luminol also gives lots of false positives - glue, fruit juice, varnish, vegetable oil etc all show up positive for blood ... i strongly suspect that its not used anywhere near as much as Hollywood would, like us to believe due to this
Not in terms of making a crime scene light up like some macabre Pollock painting, no. You apply it locally, then you need darkness for the luminescence to show and even then it's rather faint. But the stuff can definitely detect blood that's been cleaned away chemically and even after years, as long as some of the iron (or copper) catalysts remain.
I'm fairly sure that ammonia is a gas at room temperature, and quite a poisonous gas at that. That's why it's sold in it's hydroxide state. Either way, I was always told that if you can't get a stain out, if it's that important, you can always dye the rest to match.
IIRC, luminol reveals the potential presence of blood, but the sample still needs to be collected, analyzed, and scientifically categorized before it can be introduced as evidence in court.
Something something "Illuminati eats children" something something "gate" something something holy shit. Are conspiracy theorist some of the best unknown writers of all time!?
