I'm sorry by clean I mean to remove the copper from the parts.
Like a relay, I will take my end nippers and cut the plastic case off the relay. Then I take another bite with the end nippers and cut the relay in half. Then I just pull the copper off each end of the core/shaft.
For motors I cut the steel motor housing of the core if need be. I say if need because some cores pull right out like in the motors used in garage door openers, yet condenser motors the core is stuck in the housing and needs to be cut. After the core is out I put in large vise and cut off one end flush with the core.
I then turn the core over and use my end nippers to pry out the copper.
The motor windings are coated with a varnish to insulate them. The copper is #2 but sure does add up fast!
My point was that the other guys around here don't seem to take the extra time, and get full value from each air conditioning unit .
They just pull the motor and sell it for motor weight. The guys at the scrap yard love that, they just have there help do what I do and make a nice buck!
