Struggling to Clean My Beloved Philips Airfryer XXL

Around a year ago, I started using my Philips Airfryer XXL which I bought with a lot of excitement. But then, I ran into a problem. After cooking for a while, I noticed a residue on the top that looked like a layer of oil. So far, everything seemed normal. But here's the thing - I couldn't figure out how to clean that part, no matter what I tried. I'm wondering, how do I clean this stubborn residue? I have no other option but to ask the company for a solution or a refund. It's really frustrating when a device you really like starts causing you problems. Cleaning should be easy, not confusing.
