Why are steel surfaces relatively inhospitable to bacteria and other germs whereas stuff like acrylic are not?
I believe it has to do with the surface and how porous it is/isn't. Bacteria need tiny holes to hang out in (which also traps stuff they feed on), otherwise they get brushed away easily and there is less available 'food' for them. Also some metals give off ions that apparently kill bacteria.
The Short Answer
I believe it has to do with the surface and how porous it is/isn't. Bacteria need tiny holes to hang out in (which also traps stuff they feed on), otherwise they get brushed away easily and there is less available 'food' for them. Also some metals give off ions that apparently kill bacteria. I know silver does, not sure about other metals.
