Use only plastic (nylon), rubber, silicon, or wood utensils on Non-Stick cookware. Avoid sharp utensils.

Non-Stick coatings are generally made from either a silicone base, or a fluorocarbon (P.T.F.E.* - “Teflon”)) base.
Fluorocarbon coatings are applied in a 2 or 3 coat process, consisting of 1 or 2 layers of the non-stick material, plus a "sealer" or topcoat. A reinforced coating is one that utilizes the application of stainless steel particles, in a molten state, to the surface of the pan prior to coating with the nonstick material.
The main differences in quality levels are in the formulas of the liquid coating, the number of layers of coating, and the thickness of each layer. "Generic" or non-branded coatings are generally used on low end frypans, and will usually be a formula that has less durability and release qualities than branded coatings.
Even the best non-stick coatings will begin to lose their resistance to sticking, after only a few years - sooner if the pan is constantly overheated or cleaned in the dishwasher or with harsh detergents.
A good nonstick finish is absolutely smooth to the touch, and has a matte (not shiny) finish.
*Polytetrafluoroethylene is very soft ,and scratches easily.
