don't listen to the people telling you to put it in rice. putting it in front of a fan will have a much better drying effect. ancient people didn't preserve stuff by putting it in rice
I'm a repair tech and all you really can do is try to shake as much water out as possible and blow as much water out as possible. It's not just water that's a problem, it's minerals are too. The largest priority after liquid damage is to remove as much of the liquid, and when possible, rinsing individual parts with distilled water thoroughly. You do not have that option with air pods so your only bet is to attempt to rid as much water as you can. Afterwards just run a fan next to it in a dry place.
These are a terrific inexpensive item to keep on hand in general. I bought some food grade packets off of Amazon and I use them in many of my kitchen dry goods and homemade spices.
