Soft scrub and a scrubby. Finish off with glass cleaner.
Hot soap and water
I use a single edge razor blade after putting some hot water and wiping it down first. You can also use one of those old paint scrapers with a retractable single edge razor blades in it, get them at the Dollar Tree or any hardware store. This will remove all the burnt on bits and blackened grease.
Then I follow up with some Maquires stove top cleaner/polish.
I purchased the manufacturer cleaning and care kit but you can buy your own componets separately.
Currently I use the - Weiman creme with blue scotch rite pad, retractable razor paper towel options depending on the clean up job.
1- Weiman cream and paper towels for lightest soil.
2- Weiman cream and blue scotchrite pad for moderate soiling. Clean up polish with paper towel.
3- Retractable razor scraping, Weiman cream and blue scotchrite pad for heaviest build up followed by paper towel buffing.
