Anti-Bacterial Qualities of Aluminum/Titanium/etc.?

I don't know but I've experienced similar - I wash with a bit of moss, sand and water. I haven't used soap to wash my camp pot/dishes in thirty years.

None. Nada. Zero.

Now being nonporous a metal surface wouldn't stay moist or provide much in the way of shelter for microbes. But it wouldn't actively kill them either. Probably for the best: we share a LOT of DNA with microbes. Anything generally natural like metals that could kill them wouldn't be good for us to eat either.

That's why any medical equipment is thoroughly sterilized (pressurized steam for a set period, chemical treatment either liquid or gas) after each use or discarded.

I can't afford to go UL in the fight to keep the microscopic (bacteria-sized) aliens out of my brain, but a good ol' fashioned tin foil hat does offer decent protection at an affordable price.

Silly human, we dine on tin foil hats once we are already inside your head. How'd you come to want to wear the tin foil hats in the first place? We suggested it.

reuben Thank you very much. I really appreciate the laugh.

Now put your hat back on, they are hungry.

Thread. Derailed. Improved.

If cleaning your pan by licking it out concerns you, I recommend using your hand or other to carefully smash any remaining bacteria that may be alive. Also, Peeing in your pan can also be used. There is enough ammonia generated to kill off the occasional stray bacteria. This also works for sanitizing water bottles...
