A little over a month ago I accidentally purchased the Oxygen w/ chlorine (not Oxy Free) to sanitize. I brewed about 10 gallons of Pale ale and low and behold it was incredibly phenolic and not drinkable.
Now today is another brew day but I am curious; I've washed out my carboys vigorously and now I've been soaking them for about 3 hours in a warm water Oxy Free solution.
Is there any chance that any of the residual chlorine could still be in them and affect my current batch?
Thanks in advance
