From the Bench..

Here we have a Bersa .380 Thunder brought to me with a broken safety lever. I did not strip it all the way down, I just let it soak in this for a while:

Ultrasonic cleaner with the USTC method of 50% Simple Green and 50% water. Then hosed it down with Break Free and let it sit for a couple of days. 

Then reassembly with the new safety lever (broken one is upper right):

Function checked except for live fire here, off to the range tomorrow with this little handgun! I did clean the magazine. I think a cigarette butt fell out of it!
