How to clean the earwax out of AirPods

How does this even happen? How far up your ear canal do AirPods go? And how long do you keep them stuffed up there?

The reason I ask is that I have had multiple doctors in three different countries tell me that I produce more earwax than average (it’s genetic, according to them, don’t judge). I have never owned AirPods, but I have never found earwax in any of my earbuds, ever. Is this just an AirPod thing?
