I recently bought several pieces of Century Bakeware at Ocean State Job Lot. The label says the coating is Quantum 2, Whitford’s reinforced nonstick. This coating is putty-colored, and releases beautifully. The pans, though inexpensive, are heavy gauge carbon steel. Last week I used the sheet pan for the first time, to bake bacon. After hand-washing, it looked like new. The other day, I did a pan-roast of chicken and vegetables that had been tossed with a mixture of yogurt, curry powder, ginger, garlic, and oil. Again, I washed the pan in the sink (same detergent), but it retained a slight, uneven, yellowish tint that the other pans don’t have. I then gently cleaned it with a plastic scrubbie and Bar Keeper’s Friend, not wanting to damage the surface. This didn’t remove any of the discoloration.
Is this staining from the curry powder, and does it matter?
