Had an "incident" this morning with ds1 deciding he wanted to make himself some toast by turning on 2 of the rings of my hob then just leaving it 'when they got too hot'. Luckily he came upstairs where everyone else was (although didnt think to mention that he'd turned the rings on to me ) and smoke alarms went off and disaster was averted.
Unfortunately the tray for the highchair and a plastic bowl were on top of the rings and have melted all over it.
I have scraped off as much as I can with a knife while it was still warm but there is still a fine layer of plastic over them. Am thinking of buying one of the scrapers specifically designed for ceramic hobs, are they going to be much better than a knife? Is there anything else I can try?!
TIA
