the question that never concerned me… UNTIL NOW

How do you clean / disinfect / sterilize headphones…

Found this question on a message board at Head-fi.org.

Some good answers there. This never concerned me, but I could see someone reading all the bacteria-related posts here being concerned about actually sterilizing everything they own that touches anyone around them.

You can’t sterilze headphones, but you can disinfect them. Several disinfectants on the market will do nicely. Heck, Lysol is pretty solid in that regard. Best to spray it on a clean cloth and wipe things down. You don’t want to get into the drivers with it. As for the pads, if you’re really worried about them, simply buy a new set. Be aware that long term/repeated use of alcohol will dry out most materials. It will also lead to cracking and peeling of the surface finish on most headphones. We’ve gotten away from alcohol based disinfectants in my business due to that very problem. As I said, it will get to rubber, plastics, vinyl, leather, etc….if you use it long enough, eventually it will happen.

Bottom line, Lysol wipe and buy new pads. Btw, for alcohol to “sterilize” it would have to be in direct contact with the surface for at least 30 minutes, but I just don’t recommend “headphone dipping/bath”.

on… on washing hands

Firstly, I thought I am the only one who writes things On things. No, of course not! I know there are 6 billion people, don’t worry, I just think that, well, no, I don’t think :) I even have a category called “On…”.

Anyway, Indibay.org publishes an article “On Washing Hands: Surgeon’s Notes on How Infections Spread in the Hospital“. What caught my eye at first was the On part, but then I read it. Yes, that’s so true… At least I think it is, that most infections originate from doctor’s and nurse’s hands.

Each year, according to the U.S. Centers for Disease Control, two million Americans acquire an infection while they are in the hospital. Ninety thousand die of that infection. The hardest part of the infection-control team’s job, Yokoe says, is not coping with the variety of contagions they encounter or the panic that sometimes occurs among patients and staff. Instead, their greatest difficulty is getting clinicians like me to do the one thing that consistently halts the spread of infections: wash our hands.

Bigger version of this article, the original is available from Counterpunch.com, by the way:

I, too, as many students before and after me had to go through the training on how to use sterile surgical gloves. Those things are crazy! Double-packed and folded with special materials just to keep them completely sterile throughout the surgeon putting them on. Took me a while just to go through the practice of opening the container to get it to the point where the trainer agreed with me. Then, of course, I scratched my ass. No, just kidding, but I do remember doing something that she told “whoops, you’re no longer sterile”. With gloves, at least, you know or remember that you have to remain sterile, but when you’re walking around the hospital all day, touching things… You’re not sterile in 5 seconds and you’re covered in MRSA and other potentially deadly stuff in minutes. Just imagine how clean and how often docs and nurses have to wash their hands…

And still, 2,000,000 infection-related problem cases per year…Â need to wash better.

how clean are the cleaning products??

Ha ha!

NewsNet5.com publishes a short article titled “How Sanitizer Tests Are Conducted“. I love the outcome of the finding, just love it:

  • Lucky Hand Sanitizer — showed little to no reduction of bacteria count after use.
  • Sani-Doo Hand Sanitizer — showed little to no reduction of bacteria count after use.
  • April Bath & Shower Hand Sanitizer –- showed little to no reduction of bacteria count after use.
  • American Red Cross -– showed significant reduction of bacteria count after use.
  • Purell — showed significant reduction of bacteria count after use.
  • “Pure” Generic Hand Sanitizer — showed little to no reduction of bacteria count after use.
  • Family Dollar Generic Hand Sanitizer -– showed little to no reduction of bacteria count after use.
  • Target Generic Hand Sanitizer — showed significant reduction of bacteria count after use.
  • CVS Generic Hand Sanitizer — showed significant reduction of bacteria count after use.
  • Walgreens Generic Hand Sanitizer — showed significant reduction of bacteria count after use.
  • Rite Aid Generic Hand Sanitizer — showed some reduction of bacteria count after use.
  • Personal Care Hand Sanitizer — showed little to no reduction of bacteria count after use.

LOL! So, there’s only a few that actually work, huh? Wow… who allows these products on the market??? I thought FDA is supposed to be keeping a watchful eye on this kind of stuff, no? Anybody?? We’re not talking about Acinetobacter here!! Just about dirty hands… well, hands washed with cleaning products…

Hmm… strange… Oh well…

Interesting. I would like to know the response of those vendors whose products failed. Actually, this article gives me a good idea for setting up my own test of my own technology. Head-on comparison with alcohol, cleaning products, soap, etc.

wastewater treatment

A though-provoking article, nothing less!

I recall reading about cholera outbreaks through infestation of drinking water. But that was so long ago! Surely by now we have much better treatment systems, do we not? Alas, bacteria and viruses are stronger, too.

I know I will repeat it for the millionth time, but as we get rid of weaker bacteria we make room for the stronger species. In some cases, far stronger ones. I am actually curios to see the outcome of all this.

Well, whatever the case, take a look at this article on wastewater treatment published on RedOrbit.
