Hey guys,
I dumped some old loose change out of my old carboy and cleaned it. There is a spot inside of it that appears gray. I thought at first it was some type of gunk from having trashy coins inside. But I am baffled. If you scratch it on the outside, it is smooth. I tried scratching it out with a flexible piece of rubber with metal at the end from the inside. To my surprise, it feels smooth too!
Could this be a blemish in the carboy that is inside the glass between the outside and inside surface? I have attached a photo but it's hard to take a picture of glass.
Is this something to worry about?
