Ceramic cooktops are pretty. In the showroom. Where nobody has actually used them. In a kitchen where they get daily use, ceramic cooktops are a pain in the arse, because every time a pot boils over or something gets spilled, it chars a ring around the burner that won’t come off with ordinary cleaning, and you can’t just scrub it off with a pot scratcher, because you’ll scratch the stove. Gaaaah!
Fortunately, baking soda and a moderate amount of elbow grease will take care of the problem without destroying your skin or the cooktop.
For this project, you’ll need:
Baking soda
Four rags
A spray bottle filled with water
A spray bottle filled with vinegar
A Scotch-Brite pad (the off-brand is OK)
Start by spritzing down the cooktop with water.

Sprinkle baking soda over the dark rings around each burner. Lay a rag over each burner and spray it down with vinegar until it’s completely damp. The baking soda will fizz and bubble when the vinegar hits it. This chemical reaction will help loosen the charred mess that’s stuck to the burners.

Leave them on there for a half-hour or so while you go do something else, then remove one of the rags and take out after the rings with a Scotch-Brite pad and more vinegar as needed to keep the baking soda fairly wet and fizzing.

Wipe off the vinegar and baking soda, then wipe down the stove with a damp cloth to remove any residue.

The front burner you see above is the one on the right in the “before” picture below.

Feel free to gloat over your handiwork when you’re done.

You’ll have to scrub a little bit, but no more than you would if you used a commercial scouring powder, and this method is cheaper and easier on the environment.
