Furrion Greystone Manuel D'instructions page 21

DO NOT USE any metallic or wire brush to clean any
components relating th the cooktop. Some wire or metallic
brushes lose their bristles and these bristles could get stuck in the
burner ports or other small crevices and could result in a
explosion or a fire.
DO NOT ALLOW food that contains acids such as: vinegar, citrus
juices ( lemon, lime, grapefruit, etc) tomatoes, etc. to remain on
any painted, porcelain, cooktop, grates, or any other surface
relating to the gas hob. Some acids react to the paint and gloss
that is used. If an egg spill should occur, clean the egg spill when
cooktop has cooled down, do not allow the egg spill to remain on
surface.
