5 "really helped this rental cooktop" Mrs Higdon 23 March 2021 my rental's glass-look ceramic cooktop has a couple years of baked-on carbon crud. I was worried a metal scraper would gouge the hob itself. This cleaner brought my cooktop back! Cons: you still have to scrub with effort & elbow grease (i did a few rounds of scrubbing over a couple of days) & while this took off the stickiness of my oven, it didn't really clean it- but its not marketed for that. Pros: clean inoffensive scent, easy to use, cheap, and worked to get off both old crud AND thin layers of newly burnt-on bits so they DON'T build up into caked messes.
