[Fot] Ultrasonic cleaners

[John Frymark]

Marty,

Seals and gaskets should be fine. Ultrasound really only works on  
"hard" surfaces. The sonic waves are just absorbed by soft surfaces.  
As long as the heat isn't a problem, seals should OK.

I once cleaned Wheels with the tires mounted in a big cleaner. It  
worked great!
