I had lost hope with my electric cooking plates. The white circles where completely hidden under a layer of diamond-grade burn residue that no amount of scrubbing with chemicals could even begin to remove. I found this 3€ scrapping tool and it’s amazing !!! Sorry, but I don’t have the before picture, believe me after 6 years of usage, it was bad.
It can, yeah. You have to be careful to press gently in the center of the blade and not put pressure on the corners which will gouge huge scratches into glass. I have one of these for cleaning my paint pallette and get double-duty out of it on oven cleaning day.
They make cleaning kits for these stove tops that typically come with a cheaper plastic version of the tool with a weaker metal razor. Still does the job well, but less scratching chance. Also usually comes with a fine-grain polishing cream and sponges to apply it with. The cream helps to buff out lighter scratches and remove some of the cooked on stuff.
