I poured a half ounce of un diluted Star San into the bottom of a keg kettle on top of a rust spot hoping it would "Passivate"?? the rust spot. It looks like it worked pretty good in about an hour. I would like to treat the whole inside of the keg. What level of concentration would it take and how long would the solution have to sit inside of the keg to make her shine? Or is there a cheaper solution?
Thanx
