What can I use to clean a black glass electric oven top?

I have had ceramic cooktops for years. I have a tried and true method that works.

When I have light water stains and light burnt on food. I wipe the top with a wet cloth. Then I use a product especially formulated for glass top stoves called, Cerama-Bryte. I apply the product directly to the residue. I rub the stains and buildup with the product and a damp cloth. Wipe it up with a wet cloth. Spray, buff and polish with vinegar and a dry cloth and paper towel.

When I have heavy burnt on food and hard water rings. I use vinegar and a razor blade.

I keep straight vinegar in a spray bottle. I spray the vinegar on the cook top and let it set for 3 -5 minutes. Then I wipe it off with a wet cloth. I use the razor blade to scrape off the heavy burnt marks. Do not slice with the razor blade, but use the width of the razor blade with a scraping motion. Once I finish that, I wipe it off with a wet cloth. Then I apply the Cerama-Bryte directly onto the burnt residue. I scrub the spots with the product and a damp cloth. You may have to use some elbow grease to rub of the residue. Once again, I wipe the glass stop as clean as possible. I spray the glass top with the vinegar and polish it a paper towel or dry cloth.
