Claim 2:
3. A method for cleaning firearm suppressors, the method comprising:
a) providing a used suppressor having an internal cavity with a fouling material deposited on a first surface of the internal cavity, and the used suppressor also having an exterior surface;
b) providing an extender cup, which is attached to one end of the used suppressor;
c) providing a cleaning solution;
d) providing an ultra-sonic probe;
e) introducing the cleaning solution into the internal cavity of the used suppressor and adding enough cleaning solution to fill the used suppressor and at least partially fill the extender cup, wherein the cleaning solution that at least partially fills the extender cup is in fluid communication with the cleaning solution introduced into the internal cavity of the used suppressor;
f) positioning the ultra-sonic probe, such that it does not contact any inner surfaces of the suppressor during operation;
g) contacting at least part of the ultra-sonic probe with the cleaning solution that at least partially fills the extender cup;
h) operating the ultra-sonic probe;
i) projecting ultrasonic energy into the internal cavity of the used suppressor;
j) removing at least part of the fouling material from the first surface of the internal cavity of the user suppressor; and,
k) draining the cleaning solution from the used suppressor.
