Anyone know how to clean those oven top grates

use 8 Tsp baking soda, 8 Tsp blue dawn dish soap(original) and 6 Tsp vinegar, be careful adding the vinegar as when it hits the baking soda it will start foaming, stir to make a past and slather on to the racks, let sit for 10 to 15 minutes, and wipe off with a wet rag, depending on how bad the racks are, you may need to repeat. I would put them in your bath tub on a couple towels while you let them sit.

Stove top? Dishwasher. Magic eraser.

I use Awesome Orange in the spray bottle and a toothbrush.

I soak mine in Dawn liquid and hot water for about 30 min. then use a non-abrasive scrubber to remove baked on food. Works for most (but not all) baked on gunk.

Bar keepers friend works amazingly well!
