Clean Brown Sticky Baking Sheets: Oil polymerization explains dark pans; natural methods restore shine

Baking sheets often accumulate a dark, sticky residue as a result of oil polymerization when exposed to heat. Surprisingly, this buildup is harmless and can contribute to improved browning and overall cooking efficiency. To effectively clean these surfaces, natural ingredients like baking soda, lemon juice, vinegar, and salt are quite useful. To avoid such buildup in the future, consider using parchment paper or silicone mats.
