What Ph level does Neale's Brewing Supplies sanitizer remain effective to?
It has a similar ingredient list to starsan, which is listed to be effective so long as the pH of the solution is 3 or lower.
I live in an area of hard water and want to check my sanitization is up to scratch...
Also generally, how effective is this compared to StarSan? StarSan seems to be a lot more popular on the internet, but not sure if this is just because of a skew towards homebrewers in the US.
