Re: AirPods Gen2 left in Washing Machine
Have not had that experience myself, yet your question deserves some response.
About the sweat and water resistance of AirPods Pro and AirPods (3rd generation) - Apple Support
says: If your AirPods Pro or AirPods (3rd generation) are exposed to liquid:
- Wipe them clean with a soft, dry, lint-free cloth.
- Allow them to completely dry before using them or placing them in the charging case.
Keeping AirPods within acceptable operating temperatures - Apple Support
says: If your device gets too warm
If the interior temperature of the device exceeds the normal operating range, the device will protect its internal
components by attempting to regulate its temperature. If this happens, charging might slow or stop.

You may know by now whether the AirPods still work or not.
For items not under warranty ... there is a repair option and you can buy a replacement AirPod or two.
