Tried ultrasonic cleaning a greasy freehub body... big mistake

Had a sticky Shimano 105 hub from a 2019 bike. Threw the freehub body in the ultrasonic cleaner at 130 degrees with simple green. Came out looking clean but the bearings felt GRITTY after. Learned the hard way that degreaser gets past those seals every time. Anybody know a better way to clean freehub internals without tearing them completely apart?

Did you try spinning it backwards while swearing at it like I do?

Haha yeah @cora813 that method works every time for me too.

Wait you swear at your hardware and it actually works better? I gotta try that next time my phone freezes up.
