We have a freestanding oven with an electric ceramic hob. Got a new one less than 2 weeks ago, and already struggling to keep the top clean. My wonderful husband does like to overfill pans with water etc when he boils veg (especially potatoes) and so they always boil over (yes, we've had words about it lol). The top already has some stubborn marks on it. I want it kept like new as long as we can. Any cleaning tips? Until living here, I've always had gas hobs, which seem easier to clean?! Not sure what products to use to get best results. Thank you!
