Product review (4 stars): Bosch cooktop burn removal.
I purchased this cooktop and was impressed by its design.  After cooking on it one time, the left side of the stainless surface was burned.  I looked it up and found this thread.  I was sick to think this was what I was going to have to live with. I went to Meijer and purchased a $4 bottle of Easy Off Stovetop Cleaner and the burns came right off.  You have to shake the cleaner very well to get a quick result.  Watch the pan size on the outer large burners, but if you stain it, you can remove it easily.  Just thought I would share a solution.
