Step 1 Soak and Scrub the Grates
In a large bin or in the well of your sink, add enough hot water to cover the stove top grates along with a bit of soap. Dish soap is a great option as many brands are formulated to cut through grease, whether fresh or baked on. After they've been soaked for several minutes, use a metallic scouring pad to scrub baked-on grease. You'll likely not remove all of the residue in this step, but this should loosen up the stains and remove any large particles.
Step 2 Treat Grates With Ammonia
Next, move your grates into a large plastic bag or a receptacle that can be covered. Add about ¼ cup of ammonia to the bag or bin, cover it and let it sit for several hours — anywhere from three hours to overnight is recommended.
Step 3 Rinse, Dry and Treat Your Grates
Once the grates have soaked, remove them from the ammonia bath and rinse them well with warm water. This should loosen any remaining residue, although you may need to nudge stubborn spots with a scrubbing pad or sponge. Once they're clean, towel or air dry them before applying a thin layer of cooking oil to the bottoms of the grates, which will help with the prevention of rust.
For each grate from your stove, put them in a gallon size freezer bag, add 1/2 cup ammonia and seal, let it set overnight. The fumes do the work of cutting the grease.
In the morning outside, remove the grate with gloves on, you need the fresh air for ventilation. Rinse off, if needed scrub or with hot soapy water. From my 4 burner stove I do 2 at a time so I have 2 to use for cooking.
