Fancy, new ceramic stove in rental apartment... second time I used it I sprayed this "Potz" cleaner that is supposed to be specially made for ceramic stoves. Well, I didn't read the directions which say that it is supposed to be a COLD stove when you spray the cleaner. Mine was still hot. Now I have these rings/spots where the liquid got like, burned in or something. How do I fix this error? Did I just ruin my landlord's new $$stove? Is there some home remedy to use? (Also, I live in Switzerland, so... specifically American products may be difficult to find). THANK YOU TIMES A MILLION if someone's suggestion actually works...
