"Metal fragments in AirPods case.: Metal fragments of unknown origin have gotten in my case. Can't remove metal fragments from AirPods case. I'm a farmer and I assume the metal is originating from fertilizer. I can't close the lid on the case. Any ideas."

Clean your AirPod Case:
When’s the last time you cleaned these? Go here: How to Clean your AirPods and EarPods - Apple Support. There may debris getting in the way here. So, use a microfiber-cloth to clean the outside of them. Also, using a wooden toothpick, lightly slip it inside the case, seeing if you can slowly remove gunk (i.e. earwax). It may take a few tries. Tap the debris softly, and then extract the wooden toothpick, continuing until all is gotten out.
