There are many ways to get grease out of an air fryer basket. Baskets can be run under hot water to loosen the grease and make it easy to wipe away using a dishcloth. Steamers can also heat grease and loosen it. If the basket has hard to remove, baked-on grease, try soaking the basket in hot, soapy dishwater for thirty minutes to an hour. You can also try the baking soda method to break down any stuck-on grease.
