[sdiy] Ultrasonic cleaners and key grease - opinions sought!

[Steve Lenham]

Thanks all for your thoughts. Overall, it sounds like the ultrasonic 
cleaner - whilst useful for other things - might not actually be the 
right choice for what I had in mind. But that is still good to know.

I was dreaming of a solution that was quick, clean and involved minimal 
effort on my part. But as soon as you add "possible destruction of the 
workpiece" into the mix, the bubble bursts! ;-)

Cheers,

Steve L.
