How do you get thick burned grease off the grates? Scrape with a knife?
Answer Hello Nell. If it's just from spilled over food, first I would try to put them in a bucket of hot soapy water and let them soak for a while. If that doesn't work you could use oven cleaner and heat them in the oven to about 300 degrees and any food residue should come off. If it's the porcelain or enamel flaking off there is nothing you can do but replace the grates. Hope this helps!
