4 Scrub the totally cooled copper under working water to remove any last remaining bits of oxide. Be gentle, as you work not need to remove any about the red cuprous oxide that is has been created in heating the flashing.

6 Connect the lead regarding the alligator clip which fastens the clean copper plate to the positive terminal regarding the meter. The adverse terminal should then be connected to the cuprous oxide plate.
