The microphone on my Apple Watch stopped working weeks or months ago. I know the common wisdom is that Siri is useless, but I use it frequently to set timers and alarms on the Apple Watch and I missed being able to do that. Today I once again tried following the care instructions on apple.com and wiping the microphone with a clean lint-free cloth and then trying to scrub it with a toothbrush and tap water. I have tried that before and neither technique worked. Feeling reckless, I decided to poke at the microphone with the end of a dental proxabrush — and by gosh it worked! The proxabrush pulled out a small waxy, white plug, which I think was dried soap. And now the microphone picks up audio, nice and clear.

This has been a vexation to me for weeks or months and I’m happy to have it resolved.
