What liquid do people use for their airlocks?
I have been using water for a while but have recently seen people who think this isn’t best practice and is likely to get infected.
I have also found out that the sanitizer I use breaks down over time so likely wouldn’t be suitable. I have taken to using dish soap for now but don’t know if there is a problem with this practice.
I am currently avoiding vodka because of the alcohol duty in my country.

That sounds good.
What liquid to use in an airlock
I use Starsan since I already have it ready from cleaning everything else, but have used water when I forgot to save some. I’ve never had anything go funky either way.
If you’re worried about sanitizer losing effectiveness, you can change it out wherever you want, but it’s always going to be cleaner than water with no sanitizer. I just change it when I rack.
Dish soap just seems like a way to end up drinking soapy booze.
The same SO2 solution I use to sanitise my equipment. While not strictly necessary during the fermentation, as the CO2 from the fermentation is already displacing oxygen, It prevents oxygen from getting in after the fermentation has ended.
the chances of it getting infected with plain water are very low. depends on what sanitizer you use, but basically none of them will break down in the time it takes for your wort to ferment and for you to refill it.
i’ve been brewing for a long time, never had anything get infected, and i always use diluted phosphoric acid (starsan).
think about it this way; would you rather have sanitizer (safe, food grade), or soap (possibly both emetic, and laxative) in your wort?
