Ceramic Stove Top Discoloration- what to do?

Looks like you've had pots boiling over and you have hard water, I would try some lime deposit remover like CLR on a rag and let it sit on there, and then use a plastic round scrubby. Then when cooking, turn down the heat so your pots don't boil over. Otherwise I would contact the manufacturer customer service line and ask why this is happening.

Try using CERAMA BRYTE burnt on grease remover or CREAMA BRYTE cooktop cleaner. Do not use steel wool. Some day you will hate your cooktop as much as we do.

If the appliance was brand new when you moved in, then it should have come with an instruction pamphlet. What did it suggest as far as cleaners to use on the stove? What is the brand? Usually in the pamphlet there is a contact phone number or email address where owners can contact with questions about their appliance.

No, I have never heard of a New Home Warranty covering problems with appliances. They should be covered by their own policy. However, as you said, this problem does not affect the functioning of the cooktop, only the appearance. Nevertheless, you should try to contact the appliance customer service.

I use Weiman Glass Cook Top Heavy Duty cleaner & Polish. Applied with a paper towel across the surface, allowed to dry for a minute. Using paper towel the product is removed and the top is like new. Heavy stains from boil overs are removed with a razor blade scraper. The stove top is an Amana around 20 years old and still looks nice....

I use a product like Cerama Bryte and micro-fiber clothes. We moved into an apartment several years ago and the stove looked like that. I, too, tried everything I could think of, like you have, and nothing worked. I even had a can of Barkeeper's friend sent to me from the states. Then a repair man (for our refrigeration unit) told me about VITROCLEN while my father-in-law suggested I use only mirco-fiber clothes. I don't remember exactly how many times it took to restore the surface back to perfection (it did have a couple of long small scratches in the end but we couldn't see them with all the crude caked on). VITROCLEN is a thick liquid with a sort of sandy texture. I painted it on thinly with a paper paste brush used to apply paste to the wall for paper. I would then allow the product to react to the surface for about 30 minutes and then wipe it off with a dry soft old t-shirt rag. I didn't scrubb at all for the first few times. I just wiped it away and then made sure that the product was cleared of with a damp micro-fiber and dried with a dry micro-fiber cloth. I used a wooden tooth pick to test the surface after every treatment to see how well it was working. I'm pretty sure that after the 3rd or 4th time I was putting it on, allowing it to work for about 15 minutes and then making circles rotating across the surface by hand with a dry micro-fiber cloth. The same way a person applies paste wax to a car. Without any laborious effort the surface was restored. I have been using VITROCLEN for 15 years now. I use it every time I cook which is nearly 6 meals every weekend and one every weeknight. I now use paper towels and a small dab about the size of a quart. The cooktop we bought 5 years ago still looks brand new. If you use only the product to clean your cooktop it will resist stains. I also use it in the ovens and glass oven doors, on the grilling racks, the stainless steel exterior grill, the interior and door of the microwave, and the stainless steel kitchen sink as well as the ceramic sinks in the rest of the house. Good luck!
