Scratches on Glass Cooktop

The surface of my new glass cooktop is scratched and pitted after only 6 month's use. The manual warns against sliding pans over the surface--but is this material designed for people who don't actually cook? Have I actually dented the surface or am I seeing a metal residue from the pans themselves? I've tried cleaning it with a paste, but no improvement.

This may not be relevant, but the stove is a new GE, and my previous Kenmore glass cooktop survived for ten years with very little pitting and scratching. Any suggestions on how to remove the damage and avoid it in future?

  1. In response to your question - yes it is a surface for people who don't actually cook. Contact the manufacturer, they may have a suggestion on how to repair it. In the future, don't buy a glass cooktop, my experience with them has been lousy, I don't like the way they cook and you have to baby them.

      this might help...but obviously the type of pots & pans you use on the surface is important too. Good luck!

      1. First -- I am a highly skilled and avid cook with perhaps the same cooktop. I chose it over electric coil, which my house came with, and I couldn't be more pleased. I hated the coils I found in my house, and thought they were very hard to get used to. It was an older cooktop, so perhaps that was why it had such uneven heating. When I upgraded my kitchen, I wanted a high end cooktop, but cabinet size caused me to choose this GE instead of the one I originally wanted, which cost four to five times as much and had slide controls instead of knobs. Gas is not an option here, and I had cooked on gas for most of my life, so for me to say that the cooktop is a great cooktop is really something. You just need to learn the differences between the types of cooktops and adjust what you do accordingly. You only have to care for it differently. "Babying it" is a bit strong -- perhaps the other poster had some other issues with it.

        "Pitted" is the word that concerns me. Pitted glass/ceramic can crack. Did you hit it with something to chip it? If this is just metal residue that is the result of dragging an aluminum pot over the surface, the metal residue will eventually come off. It happened to me when I used a cheap pot for steaming crabs. Avoid soft materials like non-anodized aluminum, and avoid dragging if possible, because it can scratch or leave slivers of softer metals and materials. Mine lasted several months but eventually came off with regular use and cleaning with a green and yellow sponge. I also invested in a bottle of cooktop cleaner, which gently polishes it. If it is truly pitted, I would worry about cracking. I can't explain why it would pit unless you are looking at a chip.

        1. pay special attention to the use of a razor blade in cleaning. I really doubt there is anything seriously wrong. You are probably just not cleaning correctly.

          1. Perhaps I shouldn't have used the word "pitted." The glass is still perfectly smooth, as far as I can tell by touching, but there are tiny lighter colored spots all over it, which are not removed by cleaning. Perhaps this is residue from the pans that are slid over it. I use a Le Creuset dutch oven, a calphalon wok, a kettle, and heavy aluminum bottom pans.

              One more time, you have to use a razor blade in combo with the special cleaner to get the rough build up completely off.

                I have found that the pans with raw aluminum on the bottom (that is, not encased in SS, which would be SS with an aluminum core) are the culprit for the small. light marks that don't seem to come off. That would be the aluminum residue I mentioned before. The only aluminum pot I own is a crab pot, and it left these little marks. It is a dull finish on the bottom, and any movement on the burner leaves tiny silver flecks on the burner surface that don't come off with normal cleaning. They came off eventually with regular cleaning and use. I never used a razor blade, and actually never considered it because the tiny flecks looked like they were part of the glass and did not feel raised in any way.

                I use LeCreuset all the time and don't have this problem. I also use two Calphalon skillets (not my favorite since the bottoms don't sit flat), and a carbon steel wok. I even use a cast iron skillet in addition to stainless steel and copper, and some other anodized aluminum. None of these hurt the cooktop. The only pot that caused this problem was the aluminum pot. I assume it is because the surface is softer than the other materials. It seems to be more "unfinished" when you rub your hand over it.

                Just keep using the scrubbee sponge and a good glass cooktop cleaner when you clean. They will come off on a few weeks or so. And stop using aluminum pans.

                  I've been hunting answers to keeping my glass cook top looking nice and no scratches, or little. We are really letdown with having a Whirlpool Gold, black on black, cook top. No little dots to help protect the glass on this cook top. We didn’t realize how much those might help. We got ours in May 09, and had the top replaced today... Oct 15th. I had my old Maytag glass top stove maybe 12 years and while updating our kitchen we bought all new appliances. Yes, a real disappointment. Doing my homework we invested in a new set of pots and pans from Network Cooking at Kohls. Not cheap and a beautiful set. In no time at all we had scratches. We returned them and got a refund. Then we bought a new set of Corning Ware for cook tops. I haven’t used them yet on this new top. I do cook at least 2 meals each day and I clean up every time. I use Weiman glass cook top cleaner. The whole thing... and I still got the scratches. I bought an electric frying pan a few days ago because I am not so sure about using my cook top now. I don't want to see it scratched again. I did hunt the internet high and low in hopes of someone made some kind of something that you would put between the pan and glass cook top (lol) to prevent scratches. No dice... Hey, I can hope! I love cooking but I don’t want my new kitchen cook area to look scratched up. I really thought these glass cook tops were more durable. They have to last for years… and I have my doubts. I need answers or buy something else I can count on and it last.

                    My wife and i purchased new stainless steal kitchen appliances from sears just over a year ago.We decided on sears because we thought that if there ever was a problem with the product,that they would stand behind it.Boy were we wrong.We are very disapointed in Sears.The problem we have is with our glasstop stove.For about the first eight months of use everything was fine,not one scratch.Then it started. Over the next four months about 100 scratches have appeared in the glasstop.Some of the scratches are very deep.As much as we've tried to baby this stove,we have been unsucsessfull at preventing scratches from appearing.Our conclussion is that the only way to prevent scratches from appearing is not use it.Will NEVER purchase from sears ever again.

                      I a experiencing the very same thing. Stove is just a few months old and top is full so scratches and I do clean the top with Weinman stove top cleaner after every use. It's a Maytag and I am totally disappointed with this stove. What is the use of having a good stove if you cannot cook on it just to make it look good. Frustrated as I love to cook.
