I don’t know what Kleenol 30 is, but I would have thought it obvious that ethanol and isopropyl alcohol are insufficient to sterilise. My immediate thought with regard to cleanliness is always moulds. It’s not clean until it’s been soaked in sodium hypochlorite and sodium hydroxide, UV sterilised, gamma irradiated, then parked in a decaying orbit above the sun.

"I would have thought it obvious that ethanol and isopropyl alcohol are insufficient to sterilise" Especially since no hospital would rely on just ethanol and isopropyl. You'd think they'd at least try to live up to the standards of a hospital.

  Consider also that hospitals are a good place to hang out if you want to get a cleaning product and antibiotic resistant bacterial infection.

    This is why I covered my existing procedure "wounds" with loads of vaseline and securely bandaged them, before I went in for another, longer, procedure. The nurses and doctors were completely understanding and made sure to tell anyone involved, which was good to hear. Of course, I'm not sure how effective that sort of prep would be, but I hope I reduced my risk, at least.

      That’s probably a really good idea, smart thinking. It’s a wonder hospitals don’t require existing wounds to be dressed in touch a way prior to admission.

  It's a different issue. You can't autoclave your spaceship for example. Or use the same substances they use, though you might be able to use other ones

Kleenol 30 is sold as a degreaser. http://www.missionlabs.net/cleaners.html http://www.missionlabs.net/cleaners.html > A highly concentrated, industrial strength heavy-duty cleaner/degreaser. Can be used for light duty washing to heavy-duty steam cleaning. Kleenol 30 is a mix of > BENZENESULFONIC ACID, DODECYL‐, SODIUM SALT; (DODECYL BENZENE SULFONIC ACID) (CERCLA). > Fraction by Wt: 1% > SILICIC ACID (H2SIO3), DISODIUM SALT; (SILICILIC ACID DISODIUM SALT) > Fraction by Wt: 1‐4% > ETHANOL, 2‐BUTOXY‐; (ETHYLENE GLYCOL MONOBUTYL ETHER) > Fraction by Wt: 12.5% > GLYCOLS, POLYETHYLENE, MONO(NONYLPHENYL) ETHER; (NONYL PHENOL ETHOXYLATE). > Fraction by Wt: 1-5%

They don't just use chemicals, quite a lot of components are heated to a minimum of 110 centigrade as well, see https://marsmobile.jpl.nasa.gov/msl/mission/technology/insituexploration/planetaryprotection/ https://marsmobile.jpl.nasa.gov/msl/mission/technology/insit...

They didn’t test whether Kleenol was sufficient to sterilize. They were showing that without access to any other nutrient/carbon source, the bacteria were able to degrade and metabolize a variety of cleaning agents, Kleenol among those tested. That is, they weren’t saying “hey, this bullet is ineffective against that tank.” They were saying, “deprived of oil, that tank started eating bullets.”

I've been using Hibiclens (Chlorhexidine) lately after a couple of different medical procedures. Makes me wonder why Hibiclens is OK for skin use but not for use on inorganic surfaces like metal or plastic?
