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.
Most soap (at least where I am) is not antimicrobial - it cleans by removing germs from surfaces, so it doesn’t seem effective to me being put in an airlock. Not to mention the potential mess during fermentation and potential contamination of your batch.
