I may have just made a noob mistake. My stone was pretty dirty with some fairly sizable burned on sauce/cheese. I used a stainless steel spatula thing to scrape it off pretty gently. It went quickly and I didn't have to use much elbow grease at all. But then I noticed the ever so slight shine of what looks like stainless steel on the stone. Definitely not a solid layer, looks like a little bit of the spatula stayed on the stone.
Have I ruined my stone? What should I do?
