David asked: This question is related to the Cleaning of 2011 Glass Stove Tops. I’m reading posts from upset owners of several of the top brands of stove tops. They are saying that they no longer work properly only after a year’s use. Scratches have damaged their ability to transfer heat and microwaves in order to heat up the cooking pots and pans. These are not deep scars, but scratches that have happened by putting these pots and pans down onto the surface and moving them around. Is this true and are these scratches repairable?
Glass top stoves, although attractive, are notorious for scratching. Worse, many of these scratches occur during routine use. While you can often reduce the appearance of the scratches, the best solution is to prevent them altogether. Here are some tips.
- Only use pots and pans with smooth bottoms while cooking on a glass top.
- Periodically scrub the bottoms of your pans. Any burned on food will scratch and/or damage the stove.
- Clean spills as soon as they’re cool enough to safely wipe away. Sugary spills, in particular, are infamous for causing pitting.
- Never move a pan back and forth over the burner. Pick it up instead.
- Avoid contact between your glass cook top and aluminum foil. Foil can leave dark gray streaks and marks that are especially noticeable on white cook tops.
- Keep the surface clean, even when not in use. The stove doesn’t have to be hot for an item to scratch it.
In the event that your glass cook top is scratched, you can still cook on it and it should perform as well as it did before the scratch. The same is true of mild to moderate pitting. If the stove is cracked, however, you should discontinue use of the cook top immediately. Contact the manufacturer, as a relatively new stove may still be under warranty. If not, you can order a replacement cook top and fix it yourself (a fairly easy chore if you’re at all handy) or otherwise, call an appliance repair company to discuss repair or replacement.
