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.
A similar razorblade scraper came with my cooktop cleaning kit. But the liquid cleaner and scrubber almost makes it unneccary. Weiman brand.
I am not denying I have neglected regular maintenance of my cooking plates 😅
This is what amazon calls that cleaning kit if you want to look for it:
