None of them except maybe the sodium carbonate solution would kill viruses - is that important? I don't know offhand how soluble sodium carbonate is in water, but I don't think it's all that soluble; I'm not sure how alkaline the solution would be. I wouldn't use it on a surface where you are going to be preparing or eating food, either, not without rinsing well (which may be defeating the purpose unless you try to disinfect the sponge/cloth/whatever as well).
Something similar with salt water; my guess is that you'd have to dissolve a *lot* of salt in the water before it gets to the point that it would dehydrate the bacteria. And if it's that concentrated, it'll probably leave a significant salt residue on the surface. This won't be as potentially harmful as sodium carbonate, but certainly unsightly, and probably will require removal as well.
Probably the most effective would be grain alcohol - and yes, probably vodka would be best because it has relatively few impurities (unlike, for example, whiskey of equal strength). And it would evaporate quickly and leave fairly little residue. So I'd probably go with that.
(On an unrelated note: "bacteria" is plural; the singular is "bacterium". There is no such word as "bacteriae". But I knew what you meant :-) ) |
