To clean stove burner grates, soak them in warm, soapy water, and scrub with a non-metal soap pad, rinse the grates well, and seal each grate in a plastic bag with a 1/2 cup of household ammonia. Wait overnight, and rinse the grates again, then polish the grates with a soft cloth.Continue Reading
Let the grates sit in a basin of hot, soapy water for about 15 minutes to loosen burned-on particles.
Scrub the grates with non-metal soap pads to remove the loosened particles.
Hold the grates under running, warm water to remove the soap and dirt.
Place each partially-cleaned grate in a large plastic bag or container. Add 1/2 cup of household ammonia to each bag or container, and seal the bags with a rubber band or put lids on the containers.
Leave the grates overnight. The ammonia fumes chemically remove the rest of the grime.
Hold the grates under warm, running water to remove all of the ammonia and any last dirt residue.
Dry the grates with a soft cloth. Put the grates back on the stove top.
