I just looked at my stainless kettle. I was getting ready to use it again. It has a dark discoloration (pitting) at the bottom in one of the grooves around the bottom. I only use OxyClean and Star San. I'm assuming it can't be from Oxy, so it has to be from Star San. Has anyone ever had this happen? Is there anyway to reverse it? Would you still use the kettle?
Star San pitting stainless?

Do you leave it soaking for long periods of time? What kind of concentration are you using?
I dumped it, but there is a bend in the bottom where it looks like the residue pooled into. The Star San concentration might have been a little strong, but not by that much over directions. (I make it in 1 gal batches.) I've used Star San for a while now and I've never had this happen before.
