The coatings manufactured by GMM are designed for normal use in any kitchen, whether you are a professional chef or an occasional cook. The key thing to remember is to not overheat the pan, as this can cause severe damage to the cookware as well as the coating. In general, just keep an eye on the food you are preparing, and make sure that the cookware is not left on an open flame without any food or liquids inside the pan for an extended period of time.
GMM coatings are designed for use for operating temperatures well above anything that should be seen in a normal kitchen, so use your best judgment and things should be OK. Some foods may stain the metal surface but will not affect the nonstick performance at all.
While cooking, do not be afraid to really scrape the surface of your pan--the coating is very durable and will not scratch unless you really apply pressure with a sharp metal utensil. Most consumers use plastic or wooden utensils, and this unquestionably will extend the life of your nonstick cookware. Again, use your judgment and your cookware should last for years and years.
After you are done cooking, you can wash the pan in the sink or in the dishwasher, the coating will take either process very easily. Also, over time slight surface marks are totally normal and will not affect the pan's performance or durability in any way.
If, over time, you notice that there are slight chips in the nonstick surface and you wonder if you actually ate these flakes, please do not worry at all. GMM nonstick coatings are totally organic and made with materials that have been 100% approved by the FDA. Please see our "Environmental and Safety" section for more information.
