Want to Get Away With Murder? Use a Special Detergent

By Boonsri Dickinson | November 6, 2008 6:37 pm

oxygen detergentMurderers desperate to get rid of evidence might want to consider using bleach to wash away stains. But not just any bleach will do. When old-school chlorine-based bleach is splashed all over blood-stained clothing, even if the clothes are washed ten times, DNA is still detected.

So for the criminal aspiring for perfection, here’s the secret you’ll need to know: It’s the oxygen-producing detergents that will get rid of any incriminating evidence for good.

Researchers at the University of Valencia tested oxygen bleach on blood-stained clothing for two hours and found that it destroys all DNA evidence. Forensic tests such as luminal tests rely on the ability of blood to uptake oxygen: A protein in the blood called hemoglobin (responsible for transporting oxygen throughout the body) reacts with hydrogen peroxide and gives a positive test result.

Chlorine-based detergents contaminate blood, but leave behind intact hemoglobin. However, detergents such as Reckitt Benckiser’s Vanish produce oxygen bubbles, which cause the blood to degrade and no longer uptake oxygen.

Hopefully, anyone actually contemplating cleaning up bloodstains isn’t reading this.

    I don’t know where the kilers were without your helpful household hints. Does hydrogen peroxide work too?

    Thank you so much, the police haven’t tracked me down yet and I’ve been searching for a way to remove the stains from my blood-covered overalls! :-)

  • Petra

    It’s really sad that you showed such poor judgement in printing this information.

  • Cody

    Was it really necessary to post helpful tips for murderers…?

    You are some sick puppies printing information like this on the web.
    I think it borders on criminal.
    I’m hoping my granddaughter doesn’t see your sick sick picture.

    Great article.

    People who are giving you crap for printing this information just don’t get it.

    First off, it’s important that any information like this can be published; in this day and age of censorship and repression the internet is the one resouce which much be protected from this sort of thing.

    People who think that this has now given murders a way to get away with murder just don’t understand. What they are advocating is “security through obscurity,” which NEVER works and ALWAYS provides an upper hand to those in the know, meanwhile that information can be exploited by those who have ti to wreak havoc against the system.

    The only way for security to evolve is for insecure methods to be exposed.

  • karl

    moxley is spot on with his comment

  • Malik

    Thanks guys. This info is really good to know. Ive had some nasty blood stains on my jacket from a “job” I did at 3am at an abandoned warehouse in Jersey, and I thought I’d have to throw away my good clothes, but now, thanks to you, I can just wash out those annoying DNA strands, and I’m good to go. I can strut around the block, and not fear the po-lice and the man. Thanks guys!

    Moxley your a fuc head theses days it imposible to get a conviction.the modern day law doesnt work anyway because it relies on guild of mind which means the offender has to have a conscience ,to which today they dont so hey lets give them more means to not get busted.

  • Faloof

    moxley, in this case, “security through obscurity” would have been better. Murderers who know this trick wouldn’t be caught anyway, and making it public will just help others with the intention to kill someone. Nice for mass-murderers. In this case, we were more secure when this method wasn’t known. Exposing it made us insecure.

    Ok, of course authorities could now force Reckitt Benckiser to change their formula. Which I hope they do.

  • elaine

    i think this is awesome.
    there is someone in particular
    i want payback towards
    for breaking my heart.
    so thanks again :]

  • Scott Rogers

    You people are crybabies. What happened to freedom of INFORMATION at any cost. INFORMATION FOR INFORMATIONS SAKE. Give me a break. Don’t blame the person posting this information because some one murders someone else and certainly not because they get away with it. Get some lives and QUIT YR BITCHING.

  • KC

    It’s the INTERNET, people.
    THIS IS WHAT IT IS.
    it is a central repository for ALL information

    You start censoring one thing because YOU don’t like it, the whole thing fails.

    get a clue

  • imakansasenigma

    You people need to grow up. Do you think he is the only person who read the friggin report. Do you think people who need to get rid of DNA evidence can only use this product? If so, youre a moron. I can name 5 other products that do the same thing. I know this info and Im not a freakin murderer. I studied this crap in college. Crikes watch Trutv and you can learn this too. Stop persecuting the writer of this article. If you don’t like the article then dont read it but quit ur bitching and grow up

  • D Brown

    The 25% solutions of Hydrogen Peroxide sold as swimming pool cleaners (by the gallon)
    is preferable to Reckitt Benckiser’s Vanish. It is much cheaper and stronger, however care must be taken when using full strength as it is a strong oxidizer…if splashed on the skin it will instantly bleach it white with possible corresponding tissue damage.

    The chemical grades of H2O2 at strengths up to 90% are much too hazardous to use.

    By the way, H2O2 at 3% to 5% is great for getting bloodstains out of carpet or furniture if you cut yourself and bleed all over the place…

    And yes…its elementary knowledge. Anyone who’s taken a chemistry class knows all about it… ;-)

  • imakansasenigma

    Thank you D Brown. At last another voice of reason. :)

  • Charles

    That’ll cut down on the amount of clothes I have to throw into the incenerator.

  • Cindy

    Dan, is your granddaughter about to commit a crime? is that why you don’t want her to see it? i’m confused, because the pictures look like bubbles to me, well I reckon you musta downloaded the intranet before they changed the picture and thats why its changed.

  • Aditya Singhi

    I want to know , if this invention is misusued then what will happen .If a person has committed murder and got stains on clothes which he removed from vanish .Can the Law of the country prevailing ban the product or not ? Anybody who know abt this plz mail to adityar.singhi@gmail.com

    I will bne very thankful to you .

    good good bhai!!!!!!!!!!!

  • me

    in theory hydrogen peroxide should work just as well and doesnt require one to research specific brands. All unless you happen to be a serial killer with a bleach obsession
