I make liqueurs using natural products , fruits, coffee etc. I'm trying to keep my tanks a clean as possible but am having some difficulty removing a stain residue from the stainless. I've tried soaking the tanks with an Alconox solution over a couple of days . It removed some stain but not much. Any recommendations or techniques or cleaning materials will be much appreciated. I don't want to have to purchase tanks for each of my flavors.
Please comment here or if you wish email me at galinc@comcast.net
