Can always try the electorosis route. My uncle uses that meathod to clean up rusted old car parts all the time. They come out looking like new.do a YouTube search and you can easily find a full how to. You basically hook a car battery charger to the grate and completely submerge it in water. Let it sit for a bit and that's that. Best of luck.
