Clean Excavator Parts With an Ultrasonic Cleaner":

I've actually tried this on some hydraulic valve components and it worked surprisingly well. Ultrasonic cleaners are great for getting into tight spots you can’t reach manually—especially on parts with complex geometry or built-up grime. Just make sure to use a suitable cleaning solution (I used a degreaser diluted in water) and pre-rinse any heavy dirt beforehand. Also, don't forget to dry the parts thoroughly afterward to prevent rust. Definitely a game changer for refurbishing smaller excavator components!
