Re-Using Isopropyl/ethanol/bleach For Rigs

i read somewhere, can't for the life of me remember where, that you shouldn't squirt alcohol or bleach used for cleaning and sterilizing rigs back in the bottle after. i don't understand exactly why. i mean, if the alcohol/bleach is being applied to kill germs in the first place, won't putting the used stuff back in with the unused stuff kill even more? obviously i'm no doctor, but i was wondering if anyone could explain to me why this is bad

 

nobody?

 

why would you think mixing the dirty bleach back in with the clean bleach kill more germs? this is what ur asking, no?

 

bleach and ISO are so inexpensive that its a no brainer.

 

in practice yes, total no-brainer. i'm just asking out of pure curiosity, why is it that bleach that's supposed to have killed a bunch of baddies, added to bleach that hasn't, make bleach that's unsuitable? scientifically.

 

because if you keep adding pathogens .. eventually the H2O2 is diminished and you're left with H2O and a bunch of pathogens... same with ISO , eventually only H2O will remain as the alcohol evaporates..

 

i'm not sure if it makes the bleach unsuitable or not, but i do know that not only does it kill those germs, but you wanna rinse as many of them away away with the bleach and out of your rig as possible. it's possible that there could be a few really tough germs that might survive the bleach, and those that survive are likely to end up stronger. the numbers might be so low that they can't infect you, but if you keep repeating this then eventually the numbers of these really strong pathogens will reach a level where they infect you.

there's probably microorganisms that can live in bleach or isopropyl alcohol, life can evolve to survive or even thrive in almost any environment, or metabolize antibiotics as they're preferred energy source, if they are forced to adapt to such an environment ... this is the type of things that can help speed that up probably.

i would prefer fresh bleach just because dirty bleach would kinda bother my slightly OCD inclinations.

 

would this apply still if you also added fresh alcohol and removed some but not all of the dirty stuff? i.e. wash a needle, shoot the alc. back into bottle. then later, clean with a shot, shoot it in the bottle, but add some ever clear in there?

carry on my fellow curious travelers

 

if you wanna re-use something like alcohol the proper thing to do is to re-distil it. this won't work for bleach since it has solid components.

 

word. big bird. i think i'm out of questions, i'm going to go try to pop my many abcesses as though they are zits

(not really)
