How to sanitize a blade

[Idaho Jarhead]

I know as a matter of fact that bleach does not completely sterilize things like syringes of Hepatitus according to a news story that I saw a while ago.

That right there is funny!! I think you know for a fact that you watched a news story on bloodborne pathogens. The rest is not fact.

Anyway:

As OP stated, he's not conducting brain surgery, he just wants a clean blade. Wash it up in a little bleach water, rinse, dry thoroughly, and enjoy the rest of your day. :thumbup:

the disinfectant still used for blood born pathogens, also feces, and urine, is 1 and 10 part solution of bleech and water respectively.

I have heard though recently that contact time is a factor now (10 min), i do not recall that being the case when i was certified in disease transmission prevention (its not a big deal, but it is educational). things get updated all the time.

for myself i am comfortable with the bleech solution and a good wipe down.

I was wondering how I could sanitize my stainless steel blade without using a water-boiling method. I'm not using it for brain surgery, so it doesn't have to be perfectly clean. (And if you wondering, yes, I am a serial killer )

Very weird post.

Agreed, this post is VERY strange. Dilute bleach, (10%) will kill virtually any bacteria on contact and "disable" all the nasty viruses I'm aware of, such as Hep A, B, C, delta agent, HIV, varicella, herpes, etc., etc., etc. Sporulates, such as Bacillus sp. and others (anthrax), will be rendered "dead", but the spores may survive immediate contact, which is why a 10 minute "soaking" is considered sufficient for "field expedient sterilization." In other words, if you are worried about blood born pathogens from field dressing a critter, a quick spray, followed by normal cleaning should do you just fine unless, you are concerned about unusual stuff. However, one should note that the bacteria resposible for tetanus, is a spore former.

Hepatitis is pretty amazingly resilient stuff (much more so than even HIV), so it might (emphasis on "might") survive a quick rub-down with bleach. Nothing's going to survive a thorough soak, though.

Contrary to popular belief, HIV is an amazingly WEAK virus outside of the body. Very easily killed outside of its host, inside however is a completely different story.

Keep in mind there is one thing that we haven't yet been able to figure out how to kill - prions. These are the root of Mad Cow Disease and Chronic Wasting Disease. Heat, bleach, nothing does it. Thus far, nothing works.

For everything else, a good bleach soak should suffice.

Dude, WRONG ANSWER! Prions are proteins, and although RESISTANT to heat yadayada...they are not impervious. Any protein heated long enough and hot enough, it will become...just a bunch of amino acids or more likely ammonia and CO2.

Infectious particles possessing nucleic acid are dependent upon it to direct their continued replication. Prions however, are infectious by their effect on normal versions of the protein. Therefore, sterilizing prions involves the denaturation of the protein to a state where the molecule is no longer able to induce the abnormal folding of normal proteins. However, prions are generally quite resistant to proteases, heat, radiation, and formalin treatments,[35] although their infectivity can be reduced by such treatments. Effective prion decontamination relies upon protein hydrolysis or reduction and/or destruction of protein tertiary structure. Examples include bleach, caustic soda, or strong acidic detergents such as [LpH][36].

LpH is also known as "Quat" and what hospitals use to spray down stretchers and such.

IMHO for sterilizing a knife,I would not use anything less than 100% Full Strength Bleach,it's your well being that your putting at risk.Not to mention the cost of bleach is rather inexpensive .

Disinfecting Bleach kills pathogens
Hypochlorite bleach kills the pathogens - disease-causing bacteria, viruses, and fungi - most commonly found at home, including E. Coli, Salmonella and the Influenza A virus. See the bleach bottle label and make sure to use an EPA-registered disinfectant approved to kill these organisms. A strong oxidizer, bleach damages nucleic acids (DNA/RNA), lipids and fatty acids associated with the cell membrane and destroys the cellular activity of structural and functional proteins. Bacteria and viruses generally do not become resistant to the powerful oxidizing action of bleach when used at recommended dilutions.

I have from many sources (physicians) that when someone is operated on for Mad Cow Disease, the surgical instruments have to be contained and buried, they have no way of destroying the prions once contaminated. Dude.

It doesn't take much to google the subject.
