Some spots can appear inside the pan or basket of your Philips Airfryer due to incidental scratching or touching of the coating (e.g. during cleaning with harsh cleaning tools and/or while inserting the basket). This is not harmful in any way as all materials used in your Philips Airfryer are food-safe.
Note: Please avoid cleaning your airfryer with harsh cleaning tools (e.g. metal scrubbers, hard brushes) and insert the basket gently.
