Clean Your Gas Cook Top Burner Grates from Food.com: I had tried most everything to clean the porcelain enamel grates on my cooktop with little success.

When entering this "recipe", a plastic bag wasn't recognized but a ziploc was. Ignore that "ingredient" ;-)
No Scrub Method for cleaning stove burner grates: Seal in a plastic bag with a little ammonia (doesn't need to cover grates). Let sit overnight and the ammonia fumes will break down burnt on grease, etc. Next day, wipe clean with sponge.
