Alcohol is pretty much useless as an agent of sterilization. You can
grow nasty little things in it, as the entirety of the medical world
G’day; I would like to know from whence came this I can’t
quite go along with that. I would guarantee that nothing at all can
live in ethyl alcohol 90% concentration or above. I don’t think it
very likely that even 60% alcohol would allow life for more than af ew
I don’t know much about the alcohol wipes, but a piece of fresh paper
tissue well moistened with full strength alcohol - or even methylated
spirit - straight from the bottle, then used to clean earring wires
and posts would be a safe bet.
Another safe sterilent, is sodium or potassium meta bisulphITE I
habitually use 1 - 2% sodium meta bisulphite (NOT bisulphATE) for
sterilizing my well rinsed bottles preparatory to refilling with
homebrew. That is what most homebrewers use too.
I just now placed a piece of cleaned sterling silver in a 2% solution
of sodium meta bisulphite, and after 5 minutes, found it was
untarnished and unmarked. I couldn’t test it for bacteria, as I no
longer have the appropriate equipment or culture media, but I am
pretty sure it was clear of bacterial contamination too.
Whilst I’m at it, furthermore, watercress taken from a stream is
almost invariably contaminated with bugs of various types and should
be placed in a plastic lidded box, the box at least a quarter filled
with sodium bisulphITE, shaken well, left for 5 minutes, then the wash
the cress well under the tap. Delicious! - And safe.
