Pre-coated baking sheets generally need to be replaced after a long time of use

Pre-coated baking pans should generally be replaced after 1-2 years, but the specifics still depend on your usage habits and maintenance. If the coating peels off, scratches are noticeable, or the baking pan is warped, it needs to be replaced quickly, otherwise it may affect health and performance.

 I. Replacement Cycle Reference

Normal use: If used daily, it will take about 1-2 years.

Frequent use or improper maintenance: it may be scrapped within a few months.

Coating peeling or scratches: Once discovered, it is recommended to replace it to avoid the release of harmful substances.

 II. Factors Affecting Life

Usage habits: Burning with air, frying over high heat, scraping with a metal spatula or hard objects will shorten the life.

Cleaning method: Rinsing with cold water, soaking for a long time or strong acid and alkali cleaners will damage the coating.

Storage environment: Humid or high temperature environment can easily lead to rust or coating peeling.

3. Tips for Extending Life

Use gently: Avoid burning on air or frying over high heat, use a wooden spatula or silicone spatula.

Clean promptly: Clean with a soft cloth or plastic scraper while it is still warm, do not wait for the residue to dry out.

Store correctly: Cool before stacking, keep dry and avoid bumps and friction.

 IV. Purchase Recommendations

Check the certification: Choose “food grade” certification, such as compliance with the "National Food Safety Standard for Coatings and Coatings for Food Contact" (GB 4806.10—2016).

Judging from the material: stainless steel or aluminum substrates are more durable, and it is recommended to choose food-grade materials such as PTFE (polytetrafluoroethylene) for the coating.

Look at the brand: Choose a legitimate brand 

In short, check the condition of the baking tray regularly, take good care of it, and use it with greater peace of mind.
