USA Pan manufactures durable pans made of heavy-duty aluminized steel with a unique, ridged texture for added pan strength that are versatile for any recipe. Easy clean up with non-stick coating and the same rust proof design used in professional bakeries. Made in USA from globally sourced materials. To clean: Gently scrub pans with a sponge or nylon pad, mild soap, and warm water. Avoid using harsh abrasives or steel wool pads as this can harm the non-stick coating. Will naturally patina over time and become more non-stick as they are used.
