I got a new 10 gal kettle in today. As I was looking it over I noticed 3 marks about 1 1/2 inch from the top. I rubbed my hand across them, then I rubbed my short finger nail across them. My nail did snag. It’s not deep, but it’s a gauge. My concern is will this creat an issue with my brew? I hear a lot if things about bacteria and it has me concerned, or am I over paranoid.
