Well at this point I should add that I’m not saying this is safe. Just that I don’t consider spreading propanol on my skin on a regular basis safe either. At the start of COVID when docs were running out of cleaning agents there was some research for effective antiseptic agents and, IRC, they did test 70% ethanol (140° proof) and it did pretty well.
However I’m suggesting for cleaning; like something you might use on your bathroom toilet to get it really clean. For 'pods I just use the ethanol (ok, here’s the picture:
) most of the time. When I’m starting to see detachment as a result of what I’m doing I swap the next pod to alcohol for cleaning then skintac then the 'pod then, if it’s getting hot in the kitchen, an overpatch as well.
For the Dexcom G7 I always use full process; i.e. I do the alcohol clean then the skin tac then the overpatch (not Dexcom’s, which is not cool.) That’s because it needs to last 10 days and a lot does happen in 10 days.
The stuff is certainly not designed or intended to be drunk. The closest I ever got was 100° proof Scottish malt whisky. It wasn’t designed to be drunk either; it was the stuff that comes out of the still after the skanky methanol (which does kill) has been fractionated off. Normally in the production process this is diluted back down with peat water, producing the brown colouration and resulting in a liquor somewhere around 70°. I did drink it but in very small glasses and it was very very close to undrinkable. The bottle itself was mostly consumed with a per-person choice of the local water added, still completely colourless but much more like a reasonable Scottish malt.
I used to use spray 70% propanol, it worked but propanol takes longer to evaporate and when I’m changing a 'pod I’m in a hurry. I have anhydrous propanol (99.5% or so) these days but I avoid spraying that on my skin most days. I discovered that Oregon sells 95% ethanol from the local herbalist while discussing how to make plant extracts; it’s just a matter of asking (they have it under the counter) but it’s the only place for either of us to get it (this is Oregon…)
