I seem to recall an earlier discussion of sonic cleaners that mentioned possible damage to leaf springs. Is there a concern?
Hahahaha Billy... it sounds as if your neurons could use a good ultrasonic cleaning to remove the heavy accumulation of amyloid beta plaques, tau tangles, and Liberal Democrat propaganda.
Your deranged mind is probably confusing ultrasonic cleaning with electrolysis rust removal, which can cause hydrogen embrittlement in springs and hardened parts. But the problem is reversible, if you know how.
