Is there a product that easily cleans the black stuff off of stove burner grills?

Hello. - Personally, I use Mr. Clean Magic Eraser.

It does work. I have the same issue with the stove.

No paint, or coating has come off while using

the said product above.

Good Luck.

Have a nice day. :)

dawn dish soap

vinegar

baking soda

wire brush

nothing cuts through it easily

dawn mixed with vinegar is a badass degreaser, vinegar is a natural degreaser, and the baking soda will make it foam

once covered with this mixture, let it stand for a few minutes (15 should be plenty)

then brush the gunk away, straight strokes (like brushing hair) should cut away the stuff without damaging anti-stick surface

Magic eraser does a rather good pastime. i'm assuming it is a ceramic cook dinner proper the following. you may get a range proper cleanser/polisher at walmart or any shop like that and it takes those black smudges off extra effective than some thing.

Mr. Muscle, or oven cleaner. Razor blade also for spills.

put them in the sink and spray them with oven cleaner and let them soak

try oven cleaner
