How do I clean top of gas stove?

I have used a razor blade to scrape off the hard gunk that doesn't come off with normal cleaning. Very light touch. It seems to work without scratching the glass.

Plastic knifes from fast food places save lots of fingernails & don't scratch at our house! use the blunt not serrated side if in doubt!

Sprinkle all the spots with baking soda and salt. Then pour a little vinegar on that and step back. The vinegar will foam a little. Let the stuff sit about ten minutes. Then use a scrubbing sponge on the bad spots. For shine, use Windex and a soft cloth to buff the top of the stove. The same materials will clean the burners, liners, oven, and racks. Just use more and let it sit longer before you scrub. Happy Spring!!

Windex and a razor blade held at a 45 deg. angel. Spray, let sit of a minute or two, scrape gently and always at an angel. I have a sparkly clean top using this method. I don't ;like the products made for cleaning because they seem to leave a waxy coating, but I have used them to remove the really tough stuff and finished with the glass cleaner to get rid of the waxy build up and residue. Not sure if vinegar would eventually etch into the glass, but haven't tried that method since mine works for me.

Get some Barkeeper’s Friend. It’s a powder you sprinkle on and rub with a wet cloth. It’s amazing!

Anything with ammonia will eventually dull the top. My stove is over 18 years old in other than using the professional cleaners I have found Turtle Wax brand bug and tar remover is the only thing I've ever had to use. I've only used that with a professional cleaners haven't worked
