My black laminate kitchen worktops have suddenly become discoloured with whitish/greyish marks, shortly after my son used Mr Muscle oven cleaner on a couple of George Forman grills. The evidence of what caused the marks is only circumstantial at the moment but does the team think that the oven cleaner is likely to be the culprit? If so, is there a cure (other than replacing the work tops ;-) )
