Great Question Wyswid! The RIDGID 4 in. Razor Scraper FT5001 has a blade that in reverse, the rear-facing cutting edge can be used to scrape and push material in a reverse direction. I hope this helps. Eve
I suggest you use Cerema Bryte cleaner which is an amazing product that is also at Home Depot. Crumple up some aluminum foil to use as a scrubber and scrub in circular motions. I think it would work for the toughest problems. My stove is 12 years old and looks brand new.
