How To Restore The Nonstick Coating

Swiss Diamond

Like all high-quality nonstick cookware, Swiss Diamond has a specific set of Use & Care Instructions that should always be followed to maintain optimal performance. There are several common mistakes that can damage the nonstick coating of any product, including Swiss Diamond cookware.

Oil Build-Up

A dark build-up on the surface of the pan indicates oil carbonization. This occurs over time when cooking oil is used above its smoke point – extra virgin olive oil or butter is the usual culprit. The oil doesn’t damage the pan, but it can be very difficult to remove. We recommend trying a paste of baking soda and water:

Baking Soda Treatment for Nonstick Cookware

  1. Mix a solution of baking soda and water about the consistency of toothpaste
  2. Rub this solution into the pan wherever you see the dark build-up.
  3. Scrub vigorously with a non-abrasive sponge or dish rag.
  4. Rinse clean and wash with hot soapy water.
  5. Repeat as necessary.

If the oil build-up is severe, Barkeeper’s Friend® powder* may be used in place of baking soda. *Please use only the powdered Cleanser & Polish or Soft Cleanser. The Barkeeper’s Friend® Cookware Cleaner is for stainless steel only – if used on a nonstick surface, it will cause scratches and abrasions. Do not use oven cleaner, Carbon-Off®, or other harsh chemicals, as these will degrade the nonstick surface. Choosing an appropriate cooking oil and washing your pan thoroughly with hot, soapy water each time you use it will prevent this problem.


Swiss Diamond cookware is guaranteed never to warp. High-quality cast aluminum construction ensures zero warping for the lifetime of the product.


Unfortunately, there is no antidote for scratches – although they will not impair the performance of your Swiss Diamond cookware, scratches in the nonstick coating can reduce the aesthetic value of the pan. To prevent scratches, use nylon, silicone, wooden or other nonstick-friendly utensils. Items with a sharp point or edge should not be used. If your pan is scratched, it is still safe to use – the Swiss Diamond HD nonstick coating is made completely without PFOA and the aluminum body of the cookware is sealed with a plasma torch to prevent the contact of aluminum with food.


If the coating has been overheated, causing peeling or flaking of the nonstick surface, it cannot be repaired. Swiss Diamond cookware is temperature safe up to 260°C (500°F), including in the oven. Use the proper heat settings to prevent damaging your nonstick coating.
