#2 How can I clean my gas range/cooktop grates?
If you have cast iron grates, follow these steps:
Wash the grates in the dishwasher.
Coat the grates with a thin layer of cooking oil.
Bake the grates in the oven on 350˚F for 10 minutes.
If you have porcelain-coated grates, simply place them in the dishwasher and coat any unfinished areas with a thin layer of cooking oil after washing.
