Fire restoration of door hardware via ultrasonics

+++++++

I am a locksmith by trade. I run across a lot of customers that want their door handle sets refinished (cosmetic). Although I have preformed this service of polishing, as middle man, I 'understand' that State of the Art technology, through the use of ultrasonic's used in fire and restoration industries, makes this possible to offer a like service directly to my customers. My question is, no one in my area of Southern Calif. seems to be able to offer me "lead information" in applying this to my industry. Any suggestions, sites, etc. would be very much appreciated!
