Vinegar / Bleach combo (VERY useful info)

below is from an interview with Norman Miner, a researcher at microchemlam.net
--------------------------------------------------------------------- Adding white vinegar to diluted household bleach greatly increases the disinfecting power of the solution, making it strong enough to kill even bacterial spores. Researchers from MicroChem Lab, Inc. in Euless, Texas, report their findings today at the 2006 ASM Biodefense Research Meeting.
Sodium hypochlorite (NaOCl) in the form of laundry bleach is available in most households. The concentrate is about 5.25 to 6 percent NaOCl, and the pH value is about 12. Sodium hypochlorite is stable for many months at this high alkaline pH value.
"Laundry bleach is commonly diluted about 10 to 25-fold with tap water to about 2000 to 5000 parts per million of free available chlorine for use as an environmental surface disinfectant, without regard to the pH value of the diluted bleach. However, the pH value is very important for the antimicrobial effectiveness of bleach," says Norman Miner, a researcher on the study.
At alkaline pH values of about 8.5 or higher, more than 90 percent of the bleach is in the form of the chlorite ion (OCl-), which is relatively ineffective antimicrobially. At acidic pH values of about 6.8 or lower, more than 80 percent of the bleach is in the form of hypochlorite (HOCl). HOCl is about 80 to 200 times more antimicrobial than OCl-.
"Bleach is a much more effective antimicrobial chemical at an acidic pH value than at the alkaline Ph value at which bleach is manufactured and stored. A small amount of household vinegar is sufficient to lower the pH of bleach to an acidic range," says Miner.
Miner and his colleagues compared the ability of alkaline (pH 11) and acidified (pH 6) bleach dilutions to disinfect surfaces contaminated with dried bacterial spores, considered the most resistant to disinfectants of all microbes. The alkaline dilution was practically ineffective, killing all of the spores on only 2.5 percent of the surfaces after 20 minutes. During the same time period the acidified solution killed all of the spores on all of the surfaces.
"Diluted bleach at an alkaline pH is a relatively poor disinfectant, but acidified diluted bleach will virtually kill anything in 10 to 20 minutes," says Miner. "In the event of an emergency involving Bacillus anthracis spores contaminating such environmental surfaces as counter tops, desk and table tops, and floors, for example, virtually every household has a sporicidal sterilant available in the form of diluted, acidified bleach."
Miner recommends first diluting one cup of household bleach in one gallon of water and then adding one cup of white vinegar.

1 gallon is 16 cups..
1 gallon water + 1 cup bleach + 1 cup vinegar = Awesome sporicidal sterilant.
In a spray bottle it would be great for cleaning work areas. Just spray, let it sit for 15 min, and wipe away.

i think im gonna give that a go, also i only found out the other day that rubbing alcohol is generally mixed with water cos contams wont take in anything harmfull so you basically trick them with water ,genius ive been using it on a wipe straight from the bottle. so far though ive been very lucky contam wise suppose its gonna happen some day the contams i say

This sounds VERY promising and i think that everyone should read this since it seems to be exactly the type of surface cleaner we need... I bet it would work great to soak containers or tools in too.

Bleach and ammonia = Deadly chlorine gas
500ml bleach and 10 ml acetone = a few ml chloroform
methanol and bleach can form methyl hypochlorite, which is explosive.

my dad almost killed himself trying to clean a toilet, unless you got a degree in science, do not start mixing random things to experiment with bleach.

But does it kill mycelium. I know the that myc can break bleach down with no problems, but this would be interesting to see if it is dunkable.

If it can kill spores I would imagine.

I'm on Vtunnel and can't post links. Gay. So, you'll have to do the heavy lifting.
This very article has actually come up before, and RR seemed skeptical that it would work to kill mold.
search: vinegar bleach... named: "Vinegar with Bleach as a Sterlizer for surfaces" It's just below this thread's posts.
And FYI, Agar has a very similar tek used by the USDA, which employs alcohol instead of bleach.
The post with more detail is named "alcohol as good as lyson?" search: username-agar \ words-vinegar alcohol
Just tossing it out there.

Very good info. I recently heard this on a podcast with the inventor of star-san (a sanitizer), ironically enough: http://media.libsyn.com/media/basicbrewing/bbr03-29-07.mp3
Adding vinegar to diluted bleach increases it's ability to kill germs/mold/spores tremendously. Supposedly the reason is that the bleach you buy in the store actually is designed to be used to whiten laundry, and so it contains sodium hydroxide, which whitens but reduces the sanitation properties of the bleach.
This makes just about the most effective sanitizer you could use - better than iso alcohol.
