Well we've got some folks talking about Star San, I'm talking about PWB....same issue with the aluminum?
Also, anymore input on whether or not this is a problem using this fermenter going forward? My OCD is telling me that there is some type of dissolved aluminum that is now stuck on my plastic fermenter.
Aluminum does not take high or low pH. Take it from there.
Huh? Wha? Sorry, not following...
PBW will attack the surface layer on Aluminum due to higher pH. Star San has a pH lower than 3 and will attack the surface layer on Aluminum.
Production breweries use aggressive caustics that have a pH higher than PBW, and the acids that are used in breweries are more aggressive than Star San. You might discern why there are not too many Aluminum parts in a commercial brewery.
