#Passivating #stainless with citric acid | HomeBrewTalk.com - Beer, Wine, Mead, & Cider Br

Back to #CitricAcid: 5-10% solution will work. Heat and time are the other important variables. I don't know if you are asking how to make a solution with your citric crystals?? 10% solution = 10 grams/100 ml or 0.836 pounds/gallon 5% solution = 5 grams/100 ml or 0.418 pounds/gallon for passivation of #fermenters
