General Homebrew Discussion / Iodophor age
« on: Today at 05:11:18 PM »
My preferred sanitizer is iodophor. I was told years ago by a kitchen health inspector that as long as the color in the iodophor/water mix is amber, then it is effective. When left in an open container that color fades within a couple of days.
In the last year I have adjusted my packaging regimen to closed transfer into kegs (filled with sanitizer and then pushed out with CO2) before transfer. I have been reusing the sanitizer from keg to keg to keg and since I cannot see it, I have no idea if it is still amber.
The question is, does the sanitizer lose its effectiveness with age or with oxygen exposure or both?
Maybe next time I’ll take a little sample during transfer.
