Best way to clean a griddle?
This was a similar thread a few months ago.
Hands down the best way to clean a griddle, every day, is oil, salt, griddle brick. Scrape off the residue, pour about a cup of oil, about a 1/2 cup kosher salt and the polish with a stone. Use griddle scraper to remove oil and salt, wipe griddle, and then rub a little oil onto it.
I always teach my crew that a a flattop griddle is like a cast iron pan, you want to keep it seasoned so it performs beautifully. I never allow them to use griddle cleaner. Griddle cleaner will strip away the beautiful seasoning.
