Porcelain Stove Top Restoration: Bad Dull Blotches, No Fix

Summary for porcelain stove top restoration Discussion

focus_keyphrase: porcelain stove top restoration. Rebecca Perry asked how to restore the shiny black enameled porcelain finish on cast-iron stove grates after a housekeeper used the wrong cleaner and left large dull blotches. She had already tried soap and water and oven cleaner, which removed baked-on food but did not fix the damaged sheen. The manufacturer said the problem happens often, offered no restoration remedy, and suggested replacing the grates for $675 plus tax and shipping. In the thread excerpt, no repair method is given. A later commenter, Diane B Gifford, said she had the same issue on an Imperial stove and was looking for advice, which suggests the problem is common but unresolved in this discussion. The practical takeaway is that the finish appears to have been chemically dulled, and the only solution mentioned by the manufacturer was replacement, not restoration.
