Very easy brew. Tasted a bite lighter than expected, but very good overall.
I alternate this with Star San, just to make sure I kill everything. It doesn't foam like Star San and it won't stain if you diluete it according to the "no rinse" directions.
I make a 1 gallon solution and clean everything, not just my better bottles and buckets. Just fill and shake and pour out. 2 minutes later it's ready to use. I use both this and Star San, just to alternate in case there is something that one doesn't kill, the other one will.
If you make it right it wont stain. Use three mili-liters per gallon. I use a dropper to get that little amount and mix it up, and use it that day, then spill it out. I give it 2 minutes contact time, then empty with no rinsing.
I got a dropper and add 3 ml to 1 gallon to get a good sanitizer that I discard after using. At that dilution it doesn't stain, and it sanitizes with a minute of contact._x000D_It can work with hard water, which affects star san.
