Yes! Baking sheets made of aluminum or stainless steel do not contain iron and will not rust.
To get baking sheets that don't rust, opt for pure aluminum or stainless steel. Both materials are naturally rust-proof, but they perform differently in the oven.
How Can You Prevent Rust?
Hard Anodised Baking Tray by Mermaid
Unlike non-stick bakeware, these hardwearing and versatile baking trays will never flake, peel or rust. Chosen by professional chefs, and guaranteed for life. Mermaid have been making high-quality aluminium bakeware in Birmingham for over a hundred years.
These premium pans are built for lifetime durability, ensuring they will never rust, providing you with long-lasting use. Encapsulated galvanized steel rims stand strong against warping, preserving the shape and quality of your pans through numerous uses.
The healthiest baking sheet materials are uncoated stainless steel and ceramic-coated aluminum/aluminized steel. Both options are completely free of concerning chemicals like PTFE, PFOA, and PFAS (often referred to as "forever chemicals" found in traditional non-stick coatings).
If you notice that your baking pans are developing rust, the best decision would be to replace them with new ones. "The risk far outweighs the benefit of trying to recover the baking pan," Le says. Le adds that you could, in theory, rely on a phosphoric acid-based cleaner to remove the rust from your pan.
If you want to keep your baking as healthy as it is delicious, the material of your bakeware really matters. The safest options are things like stainless steel, cast iron, and good old-fashioned glass, they're sturdy, non-toxic, and won't sneak any chemicals into your food.
Don't use cooking spray or rub butter on your cookie sheets because they will make your cookies spread. I only use parchment paper because your dough will never stick and you can remove cookies in perfect shape no matter how long they sit on the tray.
Neither is universally better; it depends on what you are baking. Metal is best for even browning and crispy edges (e.g., cakes, breads, and cookies). Silicone excels in non-stick release and flexibility for intricate shapes, making it great for soft bakes, individual muffins, or molded desserts.
Dawn dish soap does not chemically remove rust on its own. However, it is an excellent degreaser that breaks down surface grime, allowing you to scrub away loose rust more effectively.
To permanently stop rust, you must completely cut off the metal's exposure to oxygen and moisture. This is achieved by first removing the flaky outer rust, chemically converting any remaining rust into a stable layer, and finally sealing it with a non-porous protective coating or paint.
If your cookie sheets are bent or cracked, they need to be replaced. Bent or cracked cookie sheets will cause your baked goods to bake unevenly. Even a dent in a cookie sheet can cause problems. If your nonstick cookie sheets are peeling or chipping, it's time for new ones.
Baking sheets rust because leftover moisture mixes with oxygen and the iron in the metal, creating a chemical reaction called oxidation. This usually happens when sheets are air-dried, improperly stored, or when protective finishes are damaged, exposing the raw metal underneath.
Just like bakeware, aluminum cookie sheets can leach aluminum into food and often contain toxic nonstick treatments. A great nonstick workaround is to use silicone baking mats on glass pans or baking sheets that are glazed with food-grade nonstick silicone.
Yes, parchment paper is generally considered safer than aluminum foil for most baking and cooking. It is an inert, non-reactive material that will not leach metals or chemicals into your meals.
Although parchment never stopped being used (primarily for governmental documents and diplomas) it had ceased to be a primary choice for artists' supports by the end of the 15th century Renaissance. This was partly due to its expense and partly due to its unusual working properties.
Parchment paper can pose health, safety, and environmental issues, primarily because of how it is manufactured and used.
The golden rules of baking
To completely avoid rust, the best baking sheet materials are stainless steel or anodized aluminum. Unlike standard baking sheets, these materials will not rust, corrode, or discolor in the dishwasher, ensuring long-term durability.
To avoid toxic chemicals like PFAS, chlorine bleach, and heavy metals, switch to certified non-toxic, unbleached parchment paper. These alternatives use natural silicone (derived from sand) for non-stick properties and are totally chlorine-free.
The healthiest cookie sheets are those free of toxic coatings like Teflon (PTFE) and PFOA. Top non-toxic options include 100% stainless steel pans, uncoated raw aluminum, and ceramic-coated bakeware.
Dawn does not chemically dissolve rust on its own, but it is an excellent tool for loosening and scrubbing away surface-level rust. Because Dawn breaks down grease and grime, it allows water and scouring pads to penetrate and lift rust off metal surfaces like griddles, tools, and hardware.
Most professional baking pans are either aluminum or aluminized steel.
