I have been so silly and sprayed internal oven cleaner on the top of my ceramic oven.. It's now got spots that when looking closely, have little white speckles in. Please can anyone recommend any products that might get these stains out?? I've been scrubbing it all night but nothing is getting them off - it looks like a stain!! Please help..!! :(
