Yes, I use S airlocks with Vodka and little to no evaporation. I like the sterile quality that vodka provides.
a K-meta solution works as well, and i was asking @ChuckD , some use a 3 piece which are horrible with evaporation , and many, many on here use cheap alcohol in our airlocks as well ,,, going back many years

I have been using the three piece ones and there is a lot of evaporation. I do have a few S airlocks. Next time I rack I’ll switch them over. Or get some of those vented bungs.

I think I’ll switch to vodka in them too.

On the other hand, I tossed all my S-locks as once they get crusty, cleaning them is REALLY hard. 3-piece locks are easy.

Everyone has their pain points! ;)

Vented bungs kick ass.
Where can you purchase vented bungs?

I have been using PBW to clean and Star San to sanitize. Meta K seems so caustic, is there a benefit to using that over Star San?
