My water is very hard.
It leaves larger water drops especially on glass, and mineral spots unless wiped off immediately.
I was thinking of adding some kind of food safe wetting agent.
Would especially like to add a wetting agent to my sanitizers so they drop clean out of glass vessels, rather than beading up.
Any suggestions?
Yes, I would [edit: use] RO-water or demi-water. If you use Star San, it’ll keep much longer as well.
Is your water from a well or municipal?
Also, wouldn’t a wetting agent be detrimental to head retention?
Good quality community well water.
Would especially like to use a wetting agent in my sanitizers; peracetic acid and Starsan - to get them to drop clean from glass and plastic rather than beading up, especially vessels used in yeast propogation. Not sure about effect on head retention. I suspect residue would be minimal in final beer product. Willing to try.
