faded gas cooktop grates
The porcelain enameled cast iron grates on our gas cooktop have faded over time, and are now a dull irregular gray. The contrast to the still bright black glass cooktop is quite noticeable. They may have gotten that way because I run them through the dishwasher occasionally. The centermost portions have retained their shiny black appearance however. This is the part of the grate that presumably gets the hottest. I would like to restore the old original appearance as much as possible. (New grates run about $45 each.) Since heat has kept the middles shiny, would putting the grates through the self cleaning cycle of the oven help recrystallize the surface of the enamel? Or would this just ruin the grates? Has anyone else had a similar experience? Did you find a solution? Thanks for you help.
