Buy Scrub Daddy or Scrub Mommy sponges.
Spray with a kitchen safe degreaser like Fuller or GP66. After letting sit, scrub. I like the Scrub Daddy that Em suggested much better than the Mommy or you could use Mr. Clean Magic Eraser.
This stuff works great for me: https://amzn.to/2VV4Zns
greased lightning works great.
Glass top? Porcelain?
I like to use coment.
Soft Scrub and a scrubby
Go to the dollar store and buy oven cleaner. Spray it on a paper towel then rub the stain. Leave there a few minutes, and wipe off. Works like a charm.
