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.

    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.
